I am using a Gem-tech One suppressor. I would like to replace the muzzle brake with the quick attach break later on. Will the suppressor be able to fit without the rail getting in the way?
Brad G on Oct 22, 2018
BEST ANSWER: It should, it's a 10 inch rail with a 10.5 inch barrel.
Does anybody have any real world data on direct mount or QD suppressors that are compatible with this complete upper? I want to purchase something but don't want to waste my money on something that turns out not fit. The nut on my factory mounted flash hider is inside the hand-guard and I know it is going to be a tight fit. Of course, my upper came from PSA with about an 1/8" gap between the receiver and the hand-guard. I do not think it was installed properly.

BEST ANSWER: Yes it will fit on any mil-spec lower.
Will this fit my PSA SPACE FORCE LOWER???

Good quality upper
Seems very well made, and looks like every other high quality upper I’ve seen. The rail is nice, but does have some sharp edges along the top. However, good and strong. First 100 rounds feed with zero issues. Used a combination of 147 and 110 grain bullet. Very good value for the money.

Well built, functioned flawlessly. Paired it with a Palmetto pistol lower. Dropped in perfectly and ran smoothly from the first round on.
I recommend this upper for any pistol build.

2A 300 10.5" Blackout Upper

Great bang for your buck
Was a little hesitant at first just because of the cost compared to big named brands but so glad I decided to buy it. I'm so happy with the quality and build of it that I went and bought another PSA upper to build another. Definitely recommend this buy.

I mounted this to a PSA pistol lower without any problems. very slight wiggle at best. Quality is as good as most all other PSA products. Has operated flawlessly. Would recommend and buy from PSA again.
