Nice firearm
Sights are cheap and by 30 rounds the hand guard walked forward about half an inch. Tightened the hand guard and through a nice Nikon scope on it and overall a great firearm. Put over 100 rounds through it no problems. I would recommend it. Very happy with palmetto state armory and this firearm. Would buy from them again.
This was pre-scope.

Did the build today went to the range put 100 rounds through it. No problems, no issues at all from opening the box through performance on the range. It,s as accurate as my more expensive ARs. Well worth the money.

Can't beat it for the price
Came out great! Paired it with a Aero Texas lower. Fit and finish are flawless, no blemishes.

This is the first build I have done with PSAs "EPT" trigger. I was pleasantly surprised, its definitely lighter and smoother than the standard milspec single stage, and very shootable.

I did re-torque the barrel nut,(which is aluminum) and I dimpled the barrel and re-secured the gas block with rocksett. If you sell me something called a "kit" I'm going to treat it as such and check everything:) I also like to torque a barrel nut to 55 lbs, a few barrel shims allowed me to line it back up to the gas tube hole.I used sleeve retainer on the handguard and torqued the screws snugly without over tightening, with a dab of blue locktite. This version of the Texas lower has a "tension screw" next to the hole for the grip screw to make the upper and lower fit tightly. This little rifle is very tight and solid, nothing moves, rattles, or shakes. It weighs less than I thought it would too.

Adding the Romeo 5 that PSA sells for $119, the generic ladder covers, and the M-Lok panels from Strike industries, brought the total I have in this build to $650.

I think its an awesome deal!

First AR-15 Build. Not my last. Good job PSA.
This was my first AR build so took my time, a little over an hour. Everything went together smoothly with the help of a few YouTube videos. First trip to the range and a 100 rounds in I'm very impressed. Shoots great, no hiccups with Federal 55 grain range ammo. I have several friends who will be buying this kit. Thanks PSA.
