Premium Palmetto State Armory (PSA) CHF AR 15 Rifle Kits

For years I’ve heard of these Palmetto State Armory AR 15 Rifle Kits. How for a few hundred bucks you can buy and build one of the best ar rifles out there. After looking at them for weeks, I finally order one. I figured why not build a new AR, RIGHT… Of course shooting it at the range showing off didn’t help. Allowing my buddies get there shots in. 

I knew it was only a matter of time before the all the questions started rolling in.

SO… (Ed, Frank, Kevin, Eric, Jason and everyone else) below I gather up all my research and all your questions/ answers. Also tossed in a few videos.
