An AR15 Pistol Kit is the next exciting build project that you’ve been waiting for. An AR Pistol can be one of the most fun, rewarding, cost-efficient builds to add to your arsenal. Our kits have been painstakingly packaged together so that builders can get every piece they need in one easy-to-build kit. Pair your kit with an optional billet or forged 80% lower, and you'll have all the components you need (grab a jig for the lower, too!) to complete your build! AR pistols utilize the same lower as a rifle, so any standard AR-15 jig will suffice.
First-time builder? Learn what an AR pistol is, and how to build one legally (without making an SBR).
Each builder is unique and has their own preferences when it comes to building and shooting - we get that. That is why we offer AR-15 Pistol Build kits chambered in 5.56 and 300 AAC Blackout. Also, the hand guard options available allow for you to easily choose a build kit that is not only the right caliber for you, but one that also allows for accessory attachments the suit your preference. Whether it be Keymod, M-Lok, QD/MOE, there is an AR Pistol Build Kit for you!

Contrary to federal law, some states have either restricted or banned the sale, transfer, and ownership of 80% lowers, firearm blanks, and other gun parts. Because of these restrictions, we cannot ship our products to certain states. Please confirm whether your state is restricted on our Shipping & Return Policy before placing an order. We cannot fulfill orders to restricted states if placed.
