I will be buying more from palmetto. I've got friends that want me to build them one. I directed them straight to palmetto. Very pleased.
Very pleased with how the build came out. I think I did pretty good for my first build. My bestfriend the army ranger I even got his seal of approval if that means anything. Ran 10 through this. Build earlier in the week. Shot like a dream. No malfunctions.
First. Build .magpul furniture.  Ept trigger.

PSA CHF 16” uppers is top tier.
This is my Third PSA CHF upper 18” 16” 14.7” and they are top tier and will compete with BCM, LWRC, and Daniel Defense but for a lower price when back in stock I will buy another one and build a recce rifle.

Outstanding! As advertised. M4 profile FN hammer forged barrel as the roll mark denotes. About as top quality as you can get. Receiver, lightweight handgaurd, gas block, etc, are all outstanding in millwork, material, finish, and assembly. The price and product is unbeatable! I highly recommend!
