If you’ve ever owned a Pistol Caliber AR you know very well that fine tuning them is all about the buffer system as most Pistol Caliber ARs are blowback so there is no gas block or gas tube at all to adjust. However, fine tuning them is a must. I was absolutely surprised by the amount of felt recoil the first time I shot my 9mm PCC. Pistol Caliber Carbines are known for breaking a Bolt Catch and increasing internal wear if you don’t figure out how to slow down the Bolt. Most people end up guessing and buying a heavy buffer of any number of ounces or will buy a number of them and try them all (that’s what I did LoL). Quarter Circle 10, the industry leader and standard for Pistol Caliber ARs, has just introduced their new Adjustable Pistol Buffer Assembly which looks like a real winner.

Adjustable Blowback Buffer Assembly for use with most pistol caliber carbines, suppressed or unsuppressed, including 9MM, .40 S&W and .45ACP. Quick change weight management allows use with multiple configurations.

Package Includes: 4 aluminum weights, 4 steel weights, 4 tungsten weights, 4 rubber spacers, buffer body and allen wrench.

  • Easy user adjustability from 5-11oz with included Aluminum, Steel, and Tungsten weights
  • Threaded retaining pin and included allen key eliminates need for hammer and punch
  • Extended length for increased bolt catch life (no spacer necessary)
  • Drop-in installation
  • For use in carbine length buffer tubes
  • Ideal for tuning your Pistol caliber AR for the best function, felt recoil, and sound suppression

Whether you’re planning a new Pistol Caliber Carbine build or wanting to fine tune your existing PCC, this might be a great answer to the perfect running gun. Check them out at www.RainierArms.com.

The new Rainier Arms Ultramatch 9mm Complete Upper is here! This complete upper was designed from the ground up by the Rainier Arms competitive shooting team to meet their specs for the perfect 9mm competition upper including a 16″ Rainier Arms Ultramatch 9mm barrel, 14″ Switch Rail, Mod2 Avalanche ambi charging handle and Faxon Firearms 9mm BCG. The 16″ Ultramatch barrel ensures the ability to make closeup shots as well as distance shots with easy all while using the same mags and ammo as your handgun.

rainier-arms-ultramatch-9-pcc-9mm-complete-upper-1Designed from the ground up in partnership with the Rainier Arms Shooting team, the Rainier Arms Ultramatch 9 PCC upper was purpose built to fit the needs of serious competitive shooters. But the Ultramatch 9 is easily multi-functional to fit any serious, hard use application. It was designed not only to be fast, but reliable and accurate and depending on the purpose, it can go from tactical to practical.

We started off with the robust Rainier Arms 9mm forged upper receiver, and used our 16″ Ultrmatch 9mm barrel with a 14″ Rainier Arms Switch rail and our Mod 2 Avalanche Charging handle lastly to help cycle the Faxon Gen 2 BCG. Every high end component we used in this build is of the best quality and was run and tested by our shooting team.

We’ve left the muzzle device as dealers choice, but we can easily thread one on for you, prior to shipping.

  • Rainier Arms 14″ Switch Rail / Keymod

While this might be the perfect competition 9mm upper it also would make for a great non-NFA / non-PISTOL upper as well for those who are looking for a quality, affordable Pistol Caliber Carbine upper that is ready to go right out of the box.

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.

Rainier Arms SBR Build 1 - Scalarworks OPS Fixed Sights Juggernaut Tactical Ambi Charging Handle - Rainier Arms Ambi Safety

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.

Rainier Arms SBR Build 2 - CMC Triggers Flat Trigger Geissele SMR MK4 rail Scalarworks OPS Fixed Sights Aimpoint Micro T1 Rainier Arms A-DAC

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. 😜

Rainier Arms SBR Build - Geissele SMR MK4 - Arisaka Inline Scout Light Mount 300 Series Scalarworks OPS Front Fixed Sight magpul vertical grip Surefire SR07

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.

Rainier Arms SBR Build - Superlative Arms - Rainier Arms - Geissele - Scalarworks - Magpul = Arisaka Rainier Arms

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. 

Rainier Arms SBR Build - rainier arms = cmc triggers = scalarworks = aimpoint t1 - juggernaut tactical - magpul - geissele

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. 

Rainier Arms SBR Build - rainier arms - geissele - cmc triggers - magpul - scalarworks - griffin armament - surefire = superlative arms piston kit - aimpoint juggernaut tactical

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.

Tyrant Designs has continued to rapidly grow their line of AR15 grips with the addition of their new HALO Series HandStop. The HALO Series HandStop shares similar curves and style as the HALO MiniVert foregrip but with a shorter body. It also is compatible with both KeyMod and MLOK….just swap the mounting hardware and you can use it on whichever rail system you want. Just like the HALO MiniVert, the HALO Series HandStop is made completely out of aluminum and has had all of the edges chamfered for a very comfortable feeling in your hand.

Its not often that I get a chance to publish a press release for a new product after actually having personal hands on experience with it. However, that is the case with the new Tyrant Designs HALO MiniVert ForeGrip. I have one, have it mounted on one of my SBRs and I can say, it’s awesome!

Tyrant CNC MiniVert 2

They obviously took a lot of time to get the shape of the all metal grip just perfect because it actually feels great in the hand. It also is easy to swap between MLOK and KeyMod by simply swapping out the screws and mounting hardware (you can save yourself $3 if you only want one set of hardware). Initially Rainier Arms got an exclusive intro price on the new HALO MiniVert ForeGrip but they sold out in just 24 hours. Thankfully Tyrant Designs, the maker of the new HALO MiniVert ForeGrip, has some left in stock at the special intro price which you can purchase at the link below. You can also read the new product press release below.

HALO MiniVert Grip (Black)

Tyrant Designs Logo

 

Tyrant Designs CNC, an industry leader in high-end aftermarket AR grips has just announced their release of the new HALO Series MiniVert, a vertical forward grip. With dimensions slightly smaller than the average AR-15 vert grip, the MiniVert sports an aggressive looking knurl and well thought out ergonomics. Coupled with the ability to fit directly to MLOK and Keymod rail systems this little grip packs a big punch. With an overall length just shy of 3 inches, Tyrant instead utilized an elongated lip at the bottom allowing the operator the option of either tucking their pinky behind or resting the finger the traditional way.

Tyrant Designs MiniVert ForeGrip 1

“With all of the positive feedback we have received from reviewers, dealers and social media, we are extremely excited to announce the official release of our HALO Series MiniVert! This concept took months of designing and field testing to make it as comfortable as possible while maintaining our well known aggressive styling. It truly is a vertical grip that can be used in all situations on various platforms to heighten the performance of the operator. We are pleased with how it came out and look forward to seeing it on AR’s everywhere. ”

We knew these would be coming out soon but didn’t know where until today. Rainier Arms has the exclusive offering of the SRS-Carbine Stealth Recoil Spring which is equivalent to a 3.3oz buffer and carbine spring.

The Stealth Recoil Spring™ SRS ™ is a self-contained multi-stage drop-in replacement for your standard buffer and spring. The Stealth Recoil Spring ™ is designed to reduce felt recoil as well as keep the buffer spring from rubbing against the inner wall of the buffer tube. The buffer mass is designed to stay under constant tension against the bolt carrier and the O-ring on the head of the buffer mass prevents metal on metal contact.
