Barrel: A proprietary blend of Hammer forged chrome molly vanadium made by FN that is referred to as "Machine Gun Steel" by virtue of its required use in FN's M249 and M240 weapons. The hammer forging process work hardens the steel, making it more durable. In addition, the chrome process for the bore allows for a lining almost twice as thick as a standard M16 for enhanced durability. Chambered in 5.56 NATO, with a 1:7 twist, M4 barrel extension, and a mid-length gas system. This heavy profile barrel is Mil-spec phosphate coated, High Pressure tested and Magnetic Particle inspected. Barrel is finished off with an F-marked front sight post with sling swivel, standard handguards and an A2 flash hider.

Upper: Forged 7075-T6 A3 AR upper is hard coat anodized black for durability. Featuring T-marks, these upper upper receivers are made for us right here in the USA.

Lower Build Kit: Includes our M4-style stock, A2 Pistol grip, Palmetto State Armory Classic Lower Parts Kit with a polished single-stage combat trigger, Mil-Spec size buffer tube, castle nut, end plate, carbine spring, and PSA Standard buffer.

Each upper is assembled to order with US-made parts, and test fired to check gas function.

A real tack driver
Just got this for a christmas present. Had to wait till now to get back in stock. But it was worth the wait even if the price jumped a 100.00 from last year. Got it put togetherand have only had a chance to shoot at 25m or so but wow if this is what the accurracy is going to be like. Three shot groups that are almost on top of each other. Loving itcan't wait to do some 300m + shooting.

Bullet stacker
This was a christmas gift. Had to wait till after firest of the year to order it though they sold out black friday.
Sucks the price jumped 100.00 bucks but I wanted this kit so there you go. As others said the pistol grip didn't tighten up properly but added a couple of washers inside the grip problem solved.It is a little barrel heavy.Finely got time to shoot some only 25 meters or so but WOW it this any sign of how accurrate it is I'm going to love this rifle its stacking the rounds.GLAD I WAITED TO GET WHAT I WANTED. If you are thinking about buying this stopjust buy it you will not regret it.

good and solid
Good value and solid quality. Built on a Anderson lower. Only had 2 problems. #1 saftey detent recess in the pistol grip was to deep. Could shake the gun and would bounce on and off safe. Replaced grip with a stock windam I had laying around problem solved(putting a bb below the spring also worked). If not for this would have given 5 stars. #2 rear takedown pin was extremely loose. After firing a few shots its now tight (think it was the lowers detent spring hole was gummed upa lil). Only shot with irons but was nailing 6" steel at 200 yards after just a few shots. 30 rounds slow aimed fire then 30 rounds aimed fast with 55gr fed fmj. The weight doesn't bother me I carried a m249 saw so dont be a wimp. Ups in my area is a nightmare.

Nail Driving SPR Kit
Great Value for money
Great Accuracy - Sub MOA capable gun with a milspec trigger. My personal best was a three shots group within the size of a dime at 100 yards with cheap 55 grain 223.
Feeds Brass and Steal - I've shot a few hundred rounds of both cheap brass 55 grain 223 & M855 62 grain Green Tip as well as dirty cheap Wolf and Tula steel case without malfunction.
Bolt and Bolt carrier are of good quality.
Spare Lower Parts - If your just looking for an upper you'll also have spare parts to complete another build or as a back up parts.

Trade off's
Very front heavy - although very accurate the barrel also makes this build very front heavy.

A pin broke within the forward assist mechanism redering the forward assist none-functioning prior to first range trip.
External barrel milling is prone to showing scratches.
Safety Selector is extremely stiff.
Needed an Accuwedge to kill the upper/lower reciver wobble when mated to a PSA AR-15 Complete Blem Lower Magpul MOE Edition - Black.
