AR15 Build Kit - 5.56mm (16" Nitride Barrel & 12" M-Lok Handguard) with Fire/Safe Marked 80% Lower

Get your hands on this mean-looking AR-15.  Then brag about having built it yourself.  This build kit gets you an AR chambered in 5.56mm NATO (yep, the same as many of the military's rifles) with an aggressive looking 12-inch M-LOK free-floating handguard.  With this kit though, we added a little bonus.  We threw out the standard lower parts kit and replaced it with an Anderson LPK.  That means you get a polished, stainless steel trigger and hammer that cycle your rifle smoothly with clean breaks every single time.  Just get some mags and ammo, and add the backup sights or optic of your choice, and you're good to go.

AR-15 Rifle Kit Details (Expanded):

Upper Assembly: This upper receiver is Forged from 7075 – T6 aluminum and is hard coat anodized black for durability. Featuring M4 feed ramp cuts, these upper receivers are made in the USA.  The upper assembly comes to you pre-assembled and ready to go.  Simply mount it onto your completed lower assembly, and add the backup sights of your choice.  Since its barrel is chambered in 5.56mm, it’s made to shoot 5.56mm NATO rounds.  You can still fire .223 from it, but your accuracy and consistency will be better if you just stick to 5.56mm.

80% Lower Receiver: This kit comes with your choice of either a forged or a billet fire and safe-engraved black 80% lower. Alternatively, choose the “No lower” option if you already have your lower picked out.  Our lower receivers are already anodized to match the upper receiver assembly perfectly. The 80% lower is ready for you to mill the trigger pocket and drill the holes for the trigger pins and safety selector.

Please note: This AR-15 build kit requires that the builder complete the 80% lower receiver themselves, but that’s the rewarding part of the experience (and the only way to build your own AR-15 without the need of an FFL transfer or serialization).
