If I take off the muzzle device will my yhm Supressor fit inside the hand guard?
Dh264 on Nov 23, 2018
BEST ANSWER: Just about every can I'm looking at is at least 1.5" in diameter (or larger). That said, I think the "best answer" is that you can't run a suppressor with this upper.
Is the inner diameter of the rail big enough to fit a suppressor in there?
Michael on Nov 26, 2018
BEST ANSWER: The upper assembly ships with the PSA Flash Can installed, which has an outer diameter of 1.2”. As long as your (insert brand here) suppressor does not have an OD greater than 1.2" you should be fine.
On the description it says nitride barrel, but in the details it says melinite ...which is it?
Gil M on Nov 20, 2018
BEST ANSWER: Same thing, they are interchangeable.*melonite
What's the inside diameter on this handguard?

Kevin on Dec 17, 2018

What barrel profile is this?
Grant P on Oct 14, 2019

Nice set up
Works and runs great. Turns heads at the range. People ask to shoot it. Amazingly good groups with the 1x6 optic on it. Takes a short package and make it reach out with a lot of punch.
PSA upper and lower with a 1x6 optic lets me "reach out" and make this short little beast a monster.

Pew pew 10.5 555 upper

My second rifle from PSA, one 16” and this 10.5”. This is now my favorite rifle. Like the sound from the flash can. The length is perfect! So far no issues after 500 rounds.
Very nice! My new favorite rifle! No complaints at all.

Awesome addition to my pistol build, functions flawlessly. Combined with PSA pistol lower, Leupold Delta point pro, Magpul MBUS, and hogue grip. Have had zero malfunctions and sub-moa groups.
