Which Bolt Carrier Group does this come with, premium or budget? I'd like to know if the bolt has "MPI" & "HPT" engraved on it? Thanks in advance!

If I wanted to build a basic budget friendly build with this what would you suggest?
Bob R on Sep 2, 2019
BEST ANSWER: If you live in a SBR friendly state I recommend you apply for one. Form 1 Individual applications are taking about a month for approval. But if you're doing a pistol build then dont worry about that. Reliability between a 10.5" and 11.5" upper is actually significant. In favor of the 11.5" that is.
Will I reach the 26 in. Over all length with this upper receiver, When assembled?
Dannt on Sep 16, 2019
BEST ANSWER: Mine was 26" exactly... and I was worried about it not EXCEEDING 26 inch. So I added the vltor/bcm a5 buffer system. The buffer tube is longer than a regular carbine tube and put my overall length at 27"
Now I have no worries.

I don't understand the special warning about purchase and ownership of uppers with a barrel length of less than 16". Isn't that the same as buying a pistol?
d r on Sep 5, 2019
BEST ANSWER: If you have one of these in your possession you want to either have a lower receiver purchased as a pistol or a stripped lower that was listed on the 4473 as ‘other’. If you have an upper with a barrel less than 16” and only a rifle lower you can be charged with constructive possession of a SBR.
Is the FSB pinned using taper pins or straight pins?
Steve H on Oct 1, 2019

The FSB uses taper pins.

Can the A2 flash hider be removed?
Joshua F on Sep 23, 2019
my state has no SBR law- I have a windham weaponry SRC 300 BO lower- will this work with a 11.5 or 10.5 upper assembly? or does the lower need be a pistol lower? or are they the same?
scott g on Oct 30, 2019
BEST ANSWER: It will work, but I believe the SBR law is a federal law and you must use a pistol lower with pistol uppers. With rifles, you need at least a 16 inch barrel.
What Bolt Carrier Group Part Number comes with this upper?
L P on Nov 7, 2019
Does this upper have triangle hanguard caps or circular? My drop in handguards only work with circle handguard caps.
Eddie on Oct 24, 2019
BEST ANSWER: Mine came with circular,and my drop in handguard fit perfectly
is the A-2 flash hider pin and welded? in respect to permanent part of barrel
edgee on Oct 29, 2019
BEST ANSWER: The FH is not pinned to the barrel. Pin and welding is usually only used with a 14.5 or 14.7 inch barrel to keep it in compliance with the NFA.
Which rear BUIS would be compatible with the F-Marked gas sight base? Thanks
Thomas B on Sep 18, 2019
BEST ANSWER: Any AR height rear sight should work.

11.5 is amazing
First off fast shipping. The 11.5 inch M4 pistol barrel absolutely great fit and Finnish love the mil spec F marked front site bolt and BCG absolutely amazing fit and Finnish along with the mil spec charging handle. I also purchased PSA Stealth lower with SBS 3 adjustable pistol brace. Fit and Finnish on both absolutely amazing. I sighted in the irons this morning its awesome waiting on my Sightmark Wolverine red dot I'm going to put on top. I absolutely love shooting this pistol especially in the 11.5 inch barrel way better than a full size AR. Ran 90 rounds 0 failure 60 Tula and 30 with brass 5.56 ran 100 rounds .22 Lr through it with my CMMG conversion ran great with mil spec rounded hammer very accurate. Thank you PSA above quality upper better than my Rockriver by far. Great price excellent quality built to last and did I mention the overall Finnish is A+++++++ buy with confidence!
November 9, 2019
Just what I expected.
This is a nice upper. It is just what I wanted. Perfect function so far. Will buy from PSA again.

Led to believe this was nitride and the bolt is not. I’m assuming only the barrel is, and on top of this I contacted Palmetto for a simple screw and they asked me to send the entire rifle in..

Accurate 11.5" barrel. Excellent price. Gives a much needed velocity advantage. I would recommend it. No issues thus far.
