Does the m-lok continue on the bottom to add m-lok short rail ?
Jim C on Apr 12, 2018
BEST ANSWER: I saw a video on youtube of a person unboxing the version of this that doesn't come with the BCG, charging handle, and sights and it appeared to have M-lok on the bottom. Take a look for yourself if you want the title of the video is "PSA 18" 223 WYELD 1/7 twist nitride barrel complete upper". Hope this helps i plan on picking one of these up in the near future as well.

Great product. Buy with confidence.
I’ve had excellent results at the range with his upper. Accurate out to 350 yards so far, using 55 grain FMJ-BT.

Great bang for the buck!
Shipped in under a week. Seems very well made, and thus far has performed well at the range. Excellent value.
Forgive the stock. We have to play these games in NY to stay within the law.

Just shot this upper for the first time. I keyholed the first three rounds at 50 yards shooting of a lead sled while zeroing with 55g range 5.56. Put 100rds through it with no ftf or fte. While I was my concerned I would have problems with my carbine buffer and tube it was very quickly put to rest as it shot fantastic with very little felt recoil. I was also very happy with the fit and finish. Using with an aero m4e1 lower couldn’t be happier

Nice 18" upper.
Basic PSA quality. The BCG includes an MPI bolt. In my first outing, it's shooting about 1 MOA using Barnes Steel Match ammo.

Excellent rifle
I have built many rifles and carbines from Palmetto State Armory.
My customers and I have always been pleased. The 18 inch is very accurate. I also have a 10 inch entry weapon that hits 6 inch plates at 200 yards with a red dot. Thanks Palmetto State Armory.
