The perfect compromise between modern design and battle proven features, this pistol build kit features a 21st century lightweight Magpul MOE M-Lok polymer handguard paired with a 10.5” barrel fitted with a reliable carbine gas system, time honored A2 front sight assembly and birdcage flash hider. It’s tough to upgrade something as venerable and proven as an AR build, but this may be one of the ideal ways to do so. Enjoy familiar design and gain the power of the M-Lok accessory mounting system to upgrade your AR pistol or SBR in new and innovative ways.

It’s tough to beat a 10.5” 5.56 NATO chambered AR pistol for sheer pleasure to own and shoot, and it’s even tougher to find fault with this delightful build. Add a rear sight or your favorite red dot or scope, and discover just how awesome a 10.5” AR pistol is.

5.56 AR Pistol Build Kit Specs (Expanded):

Barrel: 10.5", 5.56 chambered barrel comes complete with A2 Flash Hider.

Upper Receiver: This US made upper receiver is carefully forged from 7056- T6 aluminum, and finished with a durable hard black anodized finish. Built with standard M4 feed ramps and T-marked on the top rail.

Bolt Carrier Group: Made of 8620 steel, this chrome line, phosphate coated bolt is mil-spec shot peened for optimal hardness. The Carpenter 158 steel bolt carrier comes complete with extractor spring and O-ring insert. This high pressure tested full auto-style bolt carrier is built for extreme duty operations.

80% Lower Receiver: Formed from a 7075-T6 aluminum forging, our FIRE/SAFE marked black anodized and forged 80% lower is a perfect match for our upper receiver assembly. This 80% lower only needs machined for the trigger pocket, and fire control group.

AR-15 Lower Parts Kit: The MagPul MOE lower kit gives you everything you need to complete your lower assembly, including safety, pivot pin, ultra slick nickel finished trigger group, standard latch plate and the unbelievably comfortable MagPul MOE pistol grip.

Lower Assembly: Our Shockwave Pistol Lower Build Kit includes the cutting edge, accuracy enhancing Shockwave Blade stabilizer and Shockwave tube designed around the unique needs of AR-15 pistol builds.

Charging Handle: Made from durable T6061 aluminum, our charging handle is built for rugged reliable performance.

Please note: The AR-15 Pistol Build Kit only requires that you complete the 80% lower yourself. This is the best part, and allows you to enjoy the challenges and rewards of making your own personal lower at home at your own pace.

It is your responsibility to fully understand all applicable laws and regulations regarding purchase and ownership of uppers with a barrel length of less than 16".

    Best Pricing and Quality

    "Since I started building my own 80% ARs, I have always used They have the best pricing and quality of their products. They pretty much always have someone available to talk to if you have any questions, and the phone reps were knowledgeable about weapons and their products. Can�۪t beat their free shipping options, coupled with the wide variety of kits they have to offer. "


    Already started my build!

    "This 5.56 AR Pistol Kit comes stocked with everything that I wanted. Ready to build right out of the box, and it was very easy to put together. I opted for the fixed front sight because I wanted to permanently have the fixed sight, even if my optic system goes down. For me, having a backup sight post is ideal, for combat readiness of the weapon, if need be. Not to mention that the barrel is already equipped with an A2 Flash Hider, I was extremely pleased with this option when I was searching for a new weapon build. This Kit came with a MagPul Handguard, which is perfect, because I always upgrade to MagPul, so I saved a couple bucks by going with this option. My kit shipped fast, and I already have the build underway. Extremely happy with this purchase."
