16” Mid-Length Rifle Kit w/ Lightweight 13.5” Keymod Handguard

Normally, If you want to build a close-to-top-tier AR 15, you’re gonna have to cough up some serious cash and do some custom gunsmithing – but not anymore. This 16” mid-length rifle kit affords you, the at-home rifle builder, with a convenient pre-built way to own a premium black rifle without any guesswork or loads of cash spent.

This 16” upper features a lightweight, 13.5” keymod handguard, free-floated to guarantee accuracy. You’ll enjoy plenty of rail space to attach all your favorite accessories without putting added stress on the barrel. This kit’s 16” barrel is made from 4150 chrome moly steel, a hardened and accurate barrel steel that commonly affords MOA accuracy.

A forged 7075 T6 upper, full-auto bolt carrier group, Freedom trigger group, low-profile gas block, and nominal 1:7 twist rate make this rifle kit one of the most versatile, accurate, and ergonomic kits available at this price point.

Need a California-Compliant Build Kit? Follow These 4 Steps!

Ar15 80-lower

For a budget rifle kit this is a great choice. The lower was drilled and Milled out easily with no problems. The upper comes assembled so all you need do after milling is connect the upper and lower. Does not come with sights but overall great package.
