The AERO Precision monthly builder sets are one of the few things I look forward to being released every month. They’ve really kicked it up a notch lately with some amazing Cerakote finishes by the many of the best cerakote applicators in the business. This month they again are offering Builder Sets in both M4E1 (AR-15) and M5E1 (AR-10) configurations and have partnered up with Blown Deadline for a custom Burnt Bronze Woodland Camo finish that looks sick. Both builder sets include upper and lower receivers and a matching handguard in your choice of MLOK or KeyMod. The M4E1 set also comes with a matching trigger guard as well.

AERO Precision Monthly Rifle Giveaway June

Every month I get excited to see what my buddies at AERO Precision have come up with for their new Monthly Builder Set. What I’ve been really stoked to see is that lately they’ve been offering both AR-15 and AR-10 builder sets in the same month instead of just one or the other. The May Builder Sets are again offered in the M4E1 (AR-15) and M5E1 (AR-10) with an amazing Desert MAD Dragon Cerakote finish. They are also offering a limited amount of matching B5 Systems furniture. Check out the picture below then get ready to buy your set before they’re all gone.

I’ve always liked the looks of the 2A Armament receiver sets. Recently they released their new XANTHOS-LITE “LARGE FRAME” .308 receiver set which looks absolutely amazing and is super light weight at just 1 point (16 ounces) for the stripped set. The term “LARGE FRAME” just refers to your typical LR308/SR-25 receiver set. This set would make for one beautiful rifle. Check out the details and pictures below.

The XANTHOS-lite was developed to give the end user a lightweight solution for the popular “large frame” 308 (LR308/SR-25) pattern of firearms.  The XANTHOS-lite is geared towards the user who want’s quality material, design, and functionality in a large frame build. The XANTHOS-lite shares the common DPMS HIGH standard for rail height, and will accept most accessories on the market. The lightening cuts on the top of the receiver feature a tapered design to give aftermarket rails a seamless look from receiver to rail. Features such as a tensioning screw, and screw in pin for the bolt release are also included. A generous magazine well aid in reloading. The XANTHOS-lite is sold only as a matched set.

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.

QC10 9mm Build 0

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.

QC10 9mm Build 0

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.

QC10 9mm Build 2

QC10 9mm Build 2

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.

QC10 9mm Build 2

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.

QC10 9mm Build 5

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.

QC10 9mm Build 6

QC10 9mm Build 7

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.

QC10 9mm Build 7

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. 

QC10 9mm Build 7

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. 

QC10 9mm Build 7

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. 

QC10 9mm Build 7

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.

QC10 9mm Build 7

**Updated 11-18-14 at 11:30am** If you’re serious about wanting to either build a .308 AR now or even down the road, this “Daily Deal” from AERO Precision is too good to pass up. Last month AERO Precision started offering special daily deals through their email list and Facebook page. Today’s deal is a stripped M5 .308 Forged Upper Lower Receiver for just $139.99. The new M5 forged .308 receivers that AERO introduced this year are pretty awesome looking so this is a great first piece to start that new build with. If you’re looking for any AR-15 or AR-10 parts, AERO Precision is a great one-stop-shop.

Also, a new rifle giveaway just started. Enter to win an M5E1 .308 with a 16″ mid length barrel and 12″ KeyMod handguard.

Get in on the Daily Deal and November Giveaway at http://bit.ly/ap-november-specials

A while back I wrote a few articles about the new CIV Tactical SPR (Special Purpose Rifle) barrels that they were producing one at a time by hand and the extreme accuracy reputation they have. That got me thinking I needed to get my hands on one myself and do a new SPR build. My plan was to buy one of Dustin’s barrels and assemble the rifle myself but after talking to him a bit he said, “Hey, send me all of the parts you have and I’ll hand assemble it the CIV Tactical way.” I wasn’t exactly sure what that meant but it sounded cool to me. 

I already had a Tactical Firearm Solutions receiver set and Parallax Tactical rail ready to go that TFS and cerakoted a nice Sniper Gray for me. I boxed up the Upper Receiver, Rail and Gas Tube to which Dustin would add the new SPR Barrel (which comes with a matched Bolt), Gas Block and CIV Tac Flat Line Muzzle Brake. I had never had Dustin build me a complete upper and still didn’t know what the “CIV Tactical Way” meant but I was soon to find out. Along the way Dustin sent me some pictures of the progress and detailing some of the things he does to make sure you get the accuracy that his barrels and uppers are known for.

One of the first photos he sent me was showing the Bling Bling of the barrel crown that he does by hand on his lathe. 

1 CIV Tactical SPR Barrel Crown

Another set of pictures he showed me was the process of Lapping the face of the receiver threads and the rear facing side of the barrel extension. This process is typically done in precision bolt action rifles and ensures that the barrel is in perfect alignment with the upper receiver which obviously is done for increased accuracy.

1 Civ Tactical SPR Upper Lapped

1 CIV Tactical SPR Barrel Extension True

After a couple of weeks I received the assembled upper back and and couldn’t wait to get it all kitted out and take it to the range. Below is a great shot of the barrel itself before mounting the rail on the upper. As I mentioned before these barrels are completely hand made 416R Stainless Steel, 1/8 Twist and are chambered in .223 Wylde. The .223 Wylde chamber will shoot any .223 or 5.56 round but is designed to increase the accuracy of 5.56 NATO ammo. 

CIV Tactical SPR 0

The assembled upper has a Tactical Firearms Solutions Upper, Armageddon Tactical charging handle, Griffin Armament 45 degree offset Fail Safe Sights, Ares Armor NiB Bolt Carrier with CIV Tactical Match Bolt, Vortex Optics Viper PST 4-16 FFP scope, Parallax Tactical FFSSR 15″ rail, CIV Tactical 18″ SPR Match Barrel, Gas Block and Flat Line muzzle brake. 

CIV Tactical SPR 1CIV Tactical SPR 6

The lower I assembled myself and used the matching Tactical Firearms Solutions lower, Battle Arms Development Selector and EPS pin set. The EPS pins were a big help as the Cerakote made it nearly impossible to install a standard set of Takedown Pins. Even now they are very tight (which is how I like them) but the detent for a bullet tip on the other side makes it a breeze to push them through. I also used a LUTH-AR MBA1 stock that I got from MidwestPX. This stock is about half the price of comparable models such as the Magpul PRS but it still performed great, however its not quite as refined quality as you would expect. For an SPR rifle I don’t thin you would want to use anything other than a nice 2-stage trigger which is why I went with the Geissele SSA-E. I have this same trigger in other rifles and its seriously one of my favorite triggers I’ve ever used. Smooth, light take-up, you feel the wall (beginning of the second stage) and know if you pull any further that rifle is gonna go bang. The SSA-E will easily make any lower feel like a highly tuned machine.

CIV Tactical SPR 2CIV Tactical SPR 3

I mounted the Vortex Optics Viper PST 4-16 First Focal Plane scope in an American Defense Manufacturing QD mount and purchased a B&T Industries Atlas bipod. This setup really completed the rifle and man did it look sick!  

CIV Tactical SPR 9

The whole rifle just really came together perfectly but what you and I really want to know is….”How does it perform at the range?” I loaded up my rifle, some Greenline Tactical 75gr .223 ammo and headed to the 100 yard range. One thing I didn’t want to do is put the rifle in some lead sled and get accuracy data that way. I wanted to shoot it exactly how I would if I were actually using it which for me is Bipod in front, Bag in back. After getting the scope dialed onto the target it was time to do my best not to mess this up. 🙂

Civ Tactical SPR at the range

I decided to shoot 5 round groups instead of 3 just to show consistency. The following images are just a few of what I would consider excellent groups that I got out of this rifle at 100 yards. There were so many of these to choose from so I just picked three that were somewhat different. The first image shows a 5 round .5 MOA group (looks like 4 shots but the 5th went through one of the other holes). The second image shows 5 round .625 MOA group. The third image shows a 4 shot .5 MOA group with a low 5th round that knew I pulled as soon as I shot it.

1-CIV Tactical SPR Range 1

2-CIV Tactical SPR Range 2

3-CIV Tactical SPR Range 3

The upper shot absolutely perfect with zero FTE’s and zero FTF’s, bolt held open on an empty mag, it was just perfect. I own and have shot lots of other supposed “Match” barrels and many of them are so inconsistent that they made me think I was doing something wrong. The CIV Tactical Match SPR Barrel proved to be an extremely consistent rifle even in the hands of a novice precision shooter such as myself. Suffice it to say, the CIV Tactical SPR barrel is the real deal. I know there are some true shooters out there that could get even more accuracy out of this barrel. As I’ve mentioned before, I typically build all of my own AR’s but I would not hesitate even for one moment to have Dustin at CIV Tactical build me another upper. When you couple the hand made CIV Tactical barrel with the gunsmithing that Dustin does prior to assembly, it shows that precision shooting isn’t just reserved for bolt action guns. You can purchase this exact CIV Tactical SPR barrel in either 18 or 20 inch lengths with a matched Bolt right now at www.CIVTactical.com.

One of the most import part you’ll need to buy when building an AR Pistol is the correct buffer tube. The rules dictate that a Pistol can not have an way to accept a stock or any means of shouldering the weapon. A Pistol Buffer Tube is basically just a round tube that allows the AR-15’s BCG, Buffer and Buffer Spring to function but does not allow you to slide on a stock of any kind. 

Our friends over at Damage Industries just introduced two new products for the AR Pistol. First is an AR Pistol Buffer Tube that is made from 7075-T6 billet Aluminum, anodized black and features a rotation limited QD sling mount on the end of it. The second product is a cover that is designed specifically for Pistol Buffer Tubes that lets you ad some color to match the rest of the grips, rail covers, etc. on your AR Pistol. Check out the pics and details of these two new products below. 

NEW! Damage Industries pistol buffer tube with Quick-Detach swivel socket. 1.250″ outside diameter, machined from 7075 billet, hard-coat anodized to Mil-A-8625 type III. These tubes can be utilized with standard length carbine buffer and spring. Features limited-rotation QD Sling Swivel Socket at the end. $28.45

I just figured I would throw together a quick article giving you guys some links to build an affordable yet good quality AR-15. I’ve seen quite a few people lately buying off the shelf, commercial grade AR’s for $700-800. Quite a few other people have asked me for details on what I would build if I were wanting a great bang for the buck AR. With the links I have listed below, you’ll be able to put together a milspec AR-15 with quality parts for $630 plus shipping (price at time of posting). Obviously these parts are just suggestions from me and you can feel comfortable swapping out one product for another from any of these manufacturers.
