Builders know that the best rifles will not only last, but will make sure you hit your mark every time. Hell, if you can also throw on some attachments that will help steady your aim, get a clear look at your taget, or any other part that can improve your shooting experience, then you know you’ve hit the jackpot.
With this AR 15 rifle kit, you get just that, with a 15″ M-LOK lightweight free-float handguard that allows for tactical creativity. And just underneath that is a rugged 16″ nitride SOCOM barrel. All along with 6-position butt stock and lower parts kit. All you’ll need is a stripped AR-15 lower receiver, and it’s off to the range.
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.
This kit is not a firearm. It includes an assembled upper receiver, bolt carrier group, lower parts kit, and buffer assembly with buttstock.
Here’s the beginner’s guide to 80% lowers.
