Upper: Forged 7075-T6 A3 AR upper is made to MIL-SPECS and hard coat anodized black for durability. Featuring a mil-spec finish, these uppers are made for us right here in the USA by a mil-spec manufacturer.

Bolt: Bolt is made of Mil-spec shot-peened Carpenter 158 steel. Gas key is secured with grade 8 fasteners and staked per mil-spec. 

Build Kit: A high quality lower build kit with everything you need to assemble your AR-15 lower into a pistol. Features our Enhanced Polished Trigger (EPT) fire control group which features finely polished contact surfaces and then finished off with a super slick nickel coating.  This results in a trigger which is significantly smoother than a standard Mil-Spec trigger assembly. Pistol kit also includes a Shockwave Blade pistol stabilizer, Shockwave tube, Magpul MOE grip, MOE trigger guard, carbine buffer spring, and standard carbine buffer.

Smooth problem free build!
I picked up this kit to build a small and light rifle for my youngest to carry on patrol. I had a dreadnaught lower receiver kicking around the house. This kit went together very easily and has not had one single issue after firing 1000 rounds or so through.

Also, PSA is a great company. I have sent several friends, students, and customers to buy PSA gear as their first foray into the AR world. All of them have been very happy with their gear and their interactions with PSA.

2nd build
My second AR build. Put the kit onto an Aero AR-15 lower. Fit is better than my other AR. Compact and slick. Had some cycling issues, but fixed by taking apart and lubing the upper. The shockwave brace is better than expected, but still uncomfortable.
