For builders like you, nothing beats customizing your rifle, and what better way to do that than assembling it yourself. In this AR15 rifle kit you get a completed upper that comes with a 15″ M-Lok free-Float handguard with a picatinny rail that will allow you to customize your rifle to whatever your needs are, attached to a 16″ stainless steel SOCOM barrel. And of course, this kit includes an 6-position butt stock to adjust to your comfort, as well as all the fixins: lower parts kit, bolt carrier, and charging handle.
This kit comes with all parts required for assembly, except for the firearm component, a stripped lower receiver. This kit’s mil-spec configuration guarantees it will work with just about any 5.56/.223 receivers on the market.
