Great barrel for the money.

I’m actually very impressed with this barrel for the price! Couldn’t find much of a review on its accuracy when I took a chance of buying it. I figured Primary Arms would take care of me if it wasn’t any good with their great reputation they have. But I’ll tell you with subsonic 208 to 220 grain rounds I’m getting under MOA with this at 50yards and right at MOA at 100yards. Not bad for a short barrel! Can’t say the same for 7.5 to 8” barrels I’ve tried in the past unfortunately. Best I ever would get with those were 4MOA in all sorts of different brands shooting subsonic ammo. This one is a winner though! Especially for the price of it.
Decent quality barrel. Accurate out to 100 yds for sure. However, the description is misleading... This barrel cannot be suppressed without machinist modification. There is NO shoulder for a brake or suppressor to thread up to. A giant (.093") tool nose radius must be turned off at the base of the threads before you can mount anything reasonably square.
I like it

Great Barrel. Accurate to a 100 yds like said before. Had no problem with a suppressor. Highly recommend.

Finish on this barrel is top notch, youd think it was done by Glock. Fits solidly in the upper i used for this pistol build and the gas block tolerance was spot on at .7503. Accuracy at 25 yards was less than 1/2 inch. Extension is cut properly and matches up perfectly. I had zero issues with supersonics with and i dont run subs.
<br>Overall....excellent. Im betting another this week.
Can't be used as a suppressor host
I bought an upper last fall that comes with this barrel installed and after getting a can for it, I pulled the bird cage off and found that there is no shoulder for a suppressor or attachment device to index against. If you care about using a suppressor this isn't the barrel for you.
