Is this an FN barrel or one PSA makes in house?
SouthernGuns on Apr 20, 2018
BEST ANSWER: This barrel is produced by PSA in house. FN barrels will specify that they are made by FN and are their proprietary "Machine Gun Steel".
Will this .223 complete upper fit my PSA RA10 .308 Lower purchased recently from PSA?? Thanks folks Happy Holiday
James S on May 24, 2018
BEST ANSWER: uh, No. This is a .223 Wylde upper that fits standard AR-15 lowers, not AR-10. Your RA10 is for .308 caliber, just as you described, which are significantly larger.
Can this upper run 5.56 also?

What complete lower will work with this upper?
Phil W on May 1, 2018

I recently purchased an identical upper for a friend and he used a standard mil. spec lower to complete his rifle. So I would say as long as your lower is mil. spec. it should work with no problems. By the way my friend was very satisfied with the look and the construction.

Hope this helps.
Will it fire steel cased ammo reliably?
George Q on May 27, 2018
BEST ANSWER: I have never fired steel cased ammo. with the price of brass cased ammo so reasonable I have only purchased it.
The description is listed as an 18" bbl with 15" hand guard but in the pictures the bbl does not seem that much longer. Typo or old eyes on my side?
Michael C on May 25, 2018
BEST ANSWER: The photograph in this ad does seem to represent the look of the upper receiver complete accurately. Possibly the old eyes :)

PSA 18" upper
Upper arrived in good shape and in a timely manner. Cleaned up the barrel prior to shooting the upper. Fit tightly to my lower and shot quite well with military and reloads. Satisfied with the purchase. Free float hand-guard is a little "off" square with barrel but shot to point of aim when a scope was added and adjusted. Happy with the accuracy and overall looks of the unit.

I really like this product. Matched it with a PSA lower and everything is nice and tight. Heard horror stories about PSA shipping times but all of my order came in far ahead of schedule. Very pleased.

Good value, Quality finish, about 1 3/4 5 shot grouped at 100 yards with 55 grain American Eagle. Barrel cleans easy and overall its pleasing to the eye.

Excellent upper
I bought this late in 2017 and mated it to a Ruger lower. Honestly, I couldn't be happier. No problems at all, very accurate.

There were some scratches on the finish before I opened the box but other than that’s its a nice upper. The M-lok finish doesn’t match the upper receiver’s finish.
