What Steel is used for the Nitrided 10.5" - 4140 or 4150? Really interested in knowing, thank you!
BryGuy418 on May 23, 2018
BEST ANSWER: that would be 4140. in the descriptions on psa, if it doesn't state 4150, and all it says is "cmv" or "chrome moly vanadium" - its 4140.
Is the A2 flash hider removable?
charles on Apr 22, 2018
BEST ANSWER: yes it is removable, not pinned and welded.
Is the A2 flash hider removable, or is it welded on?
charles on Apr 22, 2018
BEST ANSWER: Standard 1/2x28 r hand thread. Put whatever brake or flashider you want on it. (AR 15 wise)
Is the barrel nitride inside as well or is it uncoated?
Nate L. on Jun 7, 2018
BEST ANSWER: The bore is nitrided.
Can Palmetto state armory confirm the steel type for this barrel? 4140 or 4150? It would be nice if it was just listed in the description

Best bang for buck home defence
Paired with SBA3 pistol lower it is a great 0-200 yard gun but needs a h1 or h2 buffer, really over gassed but no reliability issues

Old school upper
Flawless and accurate as expected. Waited a while for this and wanted the retro look with the carry handle. Thanks to PSA.

10.5 Nitride upper exceeds all expectations.
Arrived quickly and is in perfect condition. FSB is straight and the barrel is as accurate as I can hope for.
I've already run almost 1k rounds through it and it's become my truck/Jeep gun.

No need for a 16 inch rifle with this one in hand!!
Bought one not expecting to have a pistol out perform the normal 16 in gun. My daily carry paired w sb sob brace and stake my life and family’s protection on this pistol. No need for a 16 inch rifle since this one will perform as good or better.

Exactly as it says it is. Came within three days. No need to spend three times the money when you can get the same thing (aside from furniture) from PSA and it's still better than mil-spec. Grab em while they are hot!

Great buy!
Excellent quality upper, definitely glad I got my hands on a nitrided barrel over the phosphate. Waiting on some more CHF or 11.5-12.5” Bbls too!

I thought more over the upper looked great, the separation on the furniture kind of bugged me. Low quality furniture, bad craftsmanship. I don't know, can't wait to fire it DPMS lower kit under $400 build. Furniture in the plan anyways, good product.

One of the BEST products here.
This is one of if not the best product Palmetto sells. It is short, reliable and seems to be all quality in its build. I want to buy another one of these just to match the first one because it is so much fun and so handy as a rifle/pistol.
