Palmetto State Armory LogoI’m going to go out on a limb here and say that a good majority of you probably have at least one stripped AR-15 lower receiver laying around the house somewhere.  Whether it’s was a deal you just couldn’t pass up or one you bought because you knew you would want to use it for your next build now’s a good time to put that baby together!  Palmetto State Armory has put together a package for those of you who already have a lower receiver and the know how to put it all together.  Their 5.56 M4 Rifle Kit includes everything you need to start sending some lead down range including a 14.7″ Chrome-lined barrel with pinned A2 flash hider.  Check out the specs and pictures below.  GET SOME!! 

Everything you need to turn your stripped lower into a rifle for one low introductory price. Kit includes a PSA 14.7″ 4140 Chrome-lined, M4 carbine style upper, BCG, charging handle and our classic lower build Kit.

Upgrade to Magpul MOE furniture for $70 more.


Lower Build Kit: Includes our M4-style stock, A2 Pistol grip, Palmetto State Armory Classic Lower Parts Kit and Mil-Spec diameter buffer tube, castle nut, end plate, carbine spring, and PSA Standard buffer.

14.7″ Chrome moly barrel, chambered in 5.56 NATO, with a 1/7 twist, M4 barrel extension, and a carbine-length gas system. The M4 profile barrel is chrome-lined, lead lapped for out-of-the-box accuracy, air-gauged, phosphate coated, and finished off with an F-marked front sight post with sling swivel, carbine length-hand guards with heat shields, and a pinned A2 flash hider. The permanently pinned flash hider brings the barrel to 16″, so no special paperwork is required.

Forged 7075-T6 A3 AR upper is made to MIL-SPECS and hard coat anodized black for durability. Upper has M4 feedramps and is engraved “M4” above the gas tube hole, it features machined T marks, and a mil-spec finish. These uppers are made for us right here in the USA by a mil-spec manufacturer, and are marked with the Palmetto State Armory logo on the left side, up front, just below the rail.

Bolt is made of Mil-spec Carpenter 158 steel, Shot peened, MPI and HPT. Gas key is secured with grade 8 fasteners and staked per mil-spec. Bolt carrier is parkerized outside, chrome-lined inside, and laser engraved with the Palmetto State Armory logo.

Each upper is assembled to order with care. Please allow up to 15 business days for your upper to ship. If ordering MOE, specify color in special instructions at checkout.
