Arisaka Black Friday Sale
Arisaka Defense Labor Day Sale!
10% off site-wide with coupon code “relax” August 30 to September 5
We’ve been burning the midnight oil all Summer long in order to increase production and get some of our most popular products back in stock. Now available: 300 Series Lights, Inline and Offset Picatinny Mounts, and a new Offset Scout Mount for the MCX and MCX Virtus.
If you’ve followed AR15NEWS for any decent length of time you’ve probably noticed we build lots of ARs. Some times, as an AR builder, it’s easy to get in a rut and kind of build the same thing over and over again which gets boring. All it takes is a bit of imagination and planning and your next build can be the best one you’ve ever put together. This is the very case with my most recent build.
Believe it or not I had SBR’d this Rainier Arms forged lower well over a year ago but had no idea what I wanted to do with it. Then it came to me and I couldn’t stop thinking about it. From there it was just a matter of time before I had the parts in hand and ready to build.
Lets start out with a few closer shots. From this angle you can see the Rainier Arms ambi safety, Juggernaut Tactical ambi charging handle and Scalarworks OPS (On Point Sights) fixed rear sight.
As I mentioned above, this build got started as a Rainier Arms Forged A-DAC lower that I bought and Form 1’d just before the ATF41P effective date. I added a Rainier Arms forged upper and ambi safety, CMC Triggers Flat 3.5lb Trigger and LPK, Superlative Arms Piston Kit, Juggernaut Tactical ambi charging handle, Geissele MK4 rail and Scalarworks OPS Fixed Sights and Low Drag Mount for the Aimpoint T1 and a SureFeed Magazines 20 Round mag.
Of course as a Rainier Arms SBR build I chose to use their 10.5″ .223 Wylde barrel. Covered it with a Geissele MK4 rail, Arisaka Defense 300/IR Series Scout Light and Inline Scout Mount, SureFire SR07 switch, Scalarworks OPS Fixed Front Sight, Magpul vertical grip and Griffin Armament Taper Mount Supresspr Mount. The Superlative Arms Piston Kit gas block is under there somewhere. 😜
Here’s another angle of the business end on the new Rainier Arms SBR build. From this angle you can now see how accessible the Superlative Arms Piston Kit gas block is under the rail. This isn’t like many piston kits were you have one or two settings. Its more like a Piston Kit that has a built in fully adjustable gas block so you can really tune it in.
This next shot gives you a better idea of how tidy things are on this build. It’s got everything I need and nothing I don’t. The Scalarworks OPS fixed sights and mount for the Aimpoint T1 are absolutely amazing.
And here it is. Hope you guys enjoyed a pretty detailed look at my new Rainier Arms SBR build. In the end, this SBR turned out even better than I had pictured it but the initial imagination and passion to create another gun is what got it all started. Don’t be in too much of a hurry to just slap together the first complete rifle you can. Take your time with your next build, map it out, think about what would make you smile every time you see it and then build that.
Here’s the full run down of parts for this build. If you want to copy it, be my guest. Would make for a great AR Pistol build too.
Already had a chance to get the gas dialed in on the piston kit and man this thing is smooth. Will be getting some range time this week with this gun getting it sighted in. Will let you guys know how it runs soon.

Everyone knows that Arisaka Defense makes some awesome lights and light mounts, hand stops, sling mounts, etc. but they don’t automatically associate Arisaka with Vertical Grips. However, Arisaka has been making M-LOK, KeyMod and CMR Vertical Grips and have now partnered up with SKD Tactical to bring to market the new Vertical Grip for the Sig MPX Gen 1.
The Gen 1 MPX’s had a handguard with a proprietary mounting system so you were pretty limited to what accessories you could attach to it unless you added picatinny sections. The new Arisaka Vertical Grip mounts to the handguard without any adapters for a nice low profile setup and will be available exclusively through SKD Tactical. Check out the pics and details below.
The Arisaka Vertical Grip is a robust, minimal grip for the MPX Gen1 handguard. It features a radiused profile at the top which tapers to meet the mounting surface on the handguard, giving a low-profile feel and ergonomic comfort. Twin mounting screws and a recoil lug ensure secure attachment. The grip is hollow, with no end-cap.
Weight: 1.8 oz
The Vertical Grip is CNC machined from 6061 aluminum and MIL-A-8625 Type III hard coat anodized. Requires a 5/32″ Allen wrench for installation (not included). Made in the USA.
New for 2017 – Finger Stops for 1913 Picatinny rails and Inline Scout Mounts for Troy and VTAC Alpha handguards
Like our KeyMod, M-Lok, and CMR versions, the new Finger Stop for 1913 Picatinny rails was developed as a low profile, minimal control accessory. This new version functions well as both a forward index point or rear hand stop due to its wider shape and smooth contour. The Finger Stops are machined out of 6061 aluminum and weigh only 0.4 oz.
The new Inline Scout Mounts for Troy and VTAC Alpha handguards feature recoil lugs specific to each handguard and utilize a durable steel back plate to secure the mount. Like the KeyMod and M-Lok Inline Scout Mounts, these are made from 7075 aluminum for extra strength and include three sets of mounting holes for the light. This allows you to tuck the light up close to the top rail or move it outwards to gain additional clearance beside front sights or other accessories. Compatible with Surefire M300 and M600 Scout lights, Arisaka 300 and 600 Series lights and bodies, and the Streamlight Protac Rail Mount 1 and 2.
Be sure to check out our combination mount deals with both Surefire Scout and Streamlight Protac Rail Mount lights. These include your choice of Inline or Offset Scout Mount.

Arisaka Defense recently added 3 new products to their lineup so we figured we’d tell you about them all in one post.
First is the Low Profile Bipod Mount for Harris S-series (S-BR, S-BRM, S-L, S-LM, S-25, and S-25C) Bipods. The Low Profile Bipod Mount replaces the entire stock sling swivel interface with a minimalist Picatinny mount. Rotation limiters allow for approximately 15 degrees of cant to either side for leveling, and the mount is compatible with pod lock levers.
The Low Profile Bipod Mount places the bipod 1/8″ below the Picatinny rail, greatly reducing the overall height. Combined with its weight at just over one ounce and a short 1.4″ length, it significantly reduces bulk compared to the stock mount. Machined from billet 6061 aluminum and MIL-A-8625 Type III hard coat anodized, the Low Profile Bipod Mounts are built for rough use and long term reliability.
Next up is the Low Profile Picatinny Rails for KeyMod and MLOK. These 5 slot rails feature a reduced height to pull Picatinny accessories closer to the handguard. They also utilize three KeyMod or M-Lok fasteners which will spread the increased stress of large Picatinny accessories like bipods or vertical grips over more slots on the rail.
The Low Profile Picatinny Rails are machined out of billet 6061 aluminum and MIL-A-8625 Type III hard coat anodized.
Proudly made in the USA and available now on the Arisaka site:
Last but not least is the new SureFire M620 Adapter for Offset Scout Mounts. The Offset M620 Adapter allows Surefire M620 Scout lights to be used with our Offset Scout Mount, and preserves the adjustability, allowing for side to side placement for additional clearance around front sights or other top rail mounted accessories. The wrap-around design also keeps the light on the same plane as a M300 or M600 Scout light used without the Offset M620 Adapter.
The Offset M620 Adapter is machined from billet 6061 aluminum and MIL-A-8625 Type III hard coat anodized for durability.
A while back Arisaka Defense started offering their own take on the popular Scout Light to go along with their awesome Scout Mounts which have proven to be so popular they have had a hard time making enough light bodies to even keep them in-stock. With the success of their Scout Lights soaring, Arisaka looked for another cost effective option for their customers who needed something now and have found that in the Streamlight ProTac lights.
The Steamlight ProTac lights come with a standard picatinny rail mount that attaches to the light body the same way any other scout mount does. Arisaka has started carrying the Streamlight ProTac 1 and 2 cell lights and pairing them with their awesome Arisaka Scout Mounts at extremely affordable prices.
Coincidentally Arisaka Defense actually has 300 Series Scout Lights, 600 Series Scout Lights and the Streamlight ProTac 1 and 2 lights all in-stock right now so you have tons of options to choose from and customize a light that best meets your needs. Check all of these options out at www.ArisakaDefense.com.
If you’re looking for a great deal on some great accessories for your AR, this is right up your alley. Arisaka Defense just emailed me letting me know they have added a bunch of blem parts to their website that are fully functional but may have a slight ding or scratch or anodizing inconsistencies. All blem items are 30% OFF or MORE plus they get FREE First Class Shipping. Items such as 300 Series Light Bodies, all versions of Finger Stops, Ring, Inline and Offset Light Mounts, etc are in-stock and ready to go. Head on over to www.ArisakaDefense.com and pick up a great deal.
Arisaka Defense always puts out high quality products. I personally use a bunch of their products from Light Mounts to complete Flashlight Builds. Just this morning I received the following press release for their Inline and Offset Picatinny Mount. As you all know, KeyMod and M-LOK rails are great but what do you do with all of your lights, lasers, grips, etc. that only mount to Picatinny rail sections? You need an adapter like the ones Arisaka just released to make them compatible. What I really like about these mounts is that they are adjustable from side to side to allow a wider range of lights and accessories to fit and the KeyMod mounts incorporate the new patent pending Inverted KeyMod Screws from BCM instead of the normal. Take a look at the press release and pics below for these great mounts.
Press Release: Arisaka Inline & Offset Picatinny Mounts Released
Arisaka is pleased to release our new Inline and Offset Picatinny Mounts. The Inline version is available for KeyMod and M-Lok, while the Offset version is available for KeyMod, M-Lok, and the Centurion Arms CMR. Both KeyMod mounts utilize Bravo Company’s Patent Pending Inverted KeyMod Screws.
The Inline Picatinny Mount is designed for rail systems that feature 45 degree attachment interfaces, like the BCM KMR, Geissele SMR MK4 and MK8, Mega Arms MKM/MML/Wedge Lock, and Midwest Industries Generation 3 handguards. The height and adjustable side-to-side spacing place Picatinny based lights like the Surefire X300 and Inforce WML close to the handguard and within easy reach at the 1:30 or 10:30 clock positions.
The Offset Picatinny Mount is a combination of our Offset Scout Mount and a short Picatinny rail section, and is designed for rail systems that do not have 45 degree attachment interfaces like the Noveske NSR, Midwest Industries Generation 2, and SLR Rifleworks Solo Series handguards. Like the inline version, the mount places Picatinny based lights at the optimal 1:30 or 10:30 clock positions. The mount allows the user to adjust the lateral positioning of the Picatinny rail section for additional clearance next to front sights or other accessories.
Weight: 1.1 oz (Inline), 1.0 oz (Offset)
Material: CNC machined 6061 aluminum
Finish: MIL-A-8625 Type III hard coat anodized.

For a few years now, I have wanted to build a 9mm AR that takes Glock magazines. Mainly because the handgun I carry every day is a Glock 19. About a month ago I finally built my 9mm AR and it has been awesome. From the first round down the pipe it has run like a sewing machine with zero failures and the bolt hold open on last round is even working. Since then I have had a ton of questions asking me what specific parts I used in my build so I wanted to put all of the details together in on place for people to see and get information from. Once I have had a chance to put a ton more round through it I will follow up with a review as well.
My build started with Quarter Circle 10. They seem to be leading the pack in innovation regarding pistol caliber AR’s. They offer a Glock Small Frame lower for 9mm, 40SW, 357Sig, a Glock Large Frame lower for 45ACP and 10mm and a Colt 9mm lower as well as bolts and barrels for these as well. I wanted my AR to take the same mags as my Glock 19 so I went with the stripped Glock Small Frame 9mm Lower, 9mm BCG and 9mm 7.5″ barrel. Any AR-15 upper will do but I use a Rainier Arms mil spec forged upper minus forward assist. QC10 will be coming out with their own side charging upper with pistol caliber ejection port soon too. I also used an ALG Defense ACT trigger and need to upgrade to an ambi safety soon.
I covered the barrel with an SLR Rifleworks 8″ Solo Ultra Lite M-LOK rail. SLR rails are becoming one of my personal favorites. With such a short rail I decided to put an Arisaka Defense M-LOK Finger Stop underneath it. Its just small enough to not be in the way but big enough to keep your hand from getting too far forward. You may have noticed already but the QC10 barrels are straight blow back and do not require a Gas Tube or Gas Block.
For the muzzle device I chose the new 9mm Linear Comp from Kaw Valley Precision. I have used KVP’s Linear Comps for 300BLk and 5.56 before and the work great. Now they offer the same product in a 9mm version with a 1/2×28 thread pitch which is what I needed for the QC10 barrel. The fact that my barrel was shorter than my rail made the KVP linear comp a no brainer but it also looks sweet only sticking half way out the rail.
For my optic I chose a Vortex Optics RAZOR 3MOA red dot and mounted it to a Cross Machine Tool red dot sight mount. This is a nice light weight, compact optic setup that I feel has very fast target acquisition.
One item I recently installed was the Law Tactical Gen3 Folding Stock Adapter. At the moment I have this gun set up as an AR Pistol but will be converting it to a registered SBR with a stock soon. I love how compact the folding stock adapter makes this for transport. I can fit it in a small backpack, bag, case, etc without having to separate the upper and lower. It is quickly ready to shoot by flipping the buffer tube straight as you remove it from its concealment.
I was able to remove the extra weight at the rear of the carrier by removing the large roll pin and sliding it out. That is where the carrier extension for the Law Tactical Folding Stock Adapter goes.
The Law Tactical Gen3 Folding Stock Adapter has a lowered hinge to keep it away from your knuckles but just to be sure I am using a Fortis Manufacturing Hammer charging handle which has a really nice sized lever on it. The Hammer is one of my go to charging handles. Great build quality and affordable.
Originally I started out with a standard carbine buffer spring and carbine buffer combo. It worked just fine but the guys at QC10 told me they recommend a heavier buffer, somewhere in the 5-6 ounce range to slow the carrier down a bit. I installed a Damage Industries 5.4 ounce H3 buffer and it continues to run perfect.
Aside from a custom mag release and bolt catch assembly, the QC10 lower takes normal mil spec parts kits. You can see the Bolt Catch itself is mil spec but it is actuated by a pre-installed lever that contacts the magazine follower. This tends to be an issue with some mags as the spring pressure isn’t always strong enough to press the lever up and activate the bolt catch. This can be remedied by installing Wolf High Power springs inside the magazine. I bought a couple of SGM Tactical 33rd magazines from AIM Surplus and they seem to have better springs than the OEM ones. So far they are activating the LRBHO (last round bolt hold open) every time.
So, there you have it. That’s pretty much my build in a nut shell. As I always tell people who are intimidated with building their own AR, “Its easier than you think”. You’ll love the increased range and accuracy you get out of a 9mm AR and being able to carry one type of mags to feed both your Primary and Secondary is awesome. Let me know if you guys have any questions or comments.
The Patent Pending Arisaka Inline Ring Mount is designed to securely attach 1″ handheld lights to KeyMod and M-Lok handguards. It is a perfect match for handguards that feature 45 degree angle mounting flats, such as the Bravo Company KMR, Knight’s Armament URX 4, and Geissele Automatics SMR Mk8.
The Inline Ring Mount features multiple mounting positions for the clamping ring. When used on a 45 degree angle mounting flat, these positions allow the user to place the light closer or farther away from the top 12 o’clock rail to give clearance for front sights or other accessories. Three positions are provided, allowing an offset of up to 0.24″ from center. The outer diameter of the handheld light sits only 0.41″ above the KeyMod or M-Lok mounting surface, making the entire unit very low profile.
Additionally, the mount can be used in a cantilever fashion, with the end of it protruding past the front of the handguard. This can be useful with short handguards to help reduce barrel or suppressor shadows. The mount can also be reversed, allowing further flexibility for positioning your light.
Weight: 1 oz.
Material: CNC machined 6061 aluminum.
Finish: MIL-A-8625 Type III hard coat anodized.
