Is the flash hider removable or is it pinned and welded?
Mike A on May 2, 2018
BEST ANSWER: It is standard flash hider that is threaded on and is removable.
Check out a couple videos I made of my PSA purchases.
Can you put a quad rail on this upper without having to move the front site gas block?
Bcamp on Jul 5, 2018
BEST ANSWER: You can add MOE rail sections to the handguard to you want to add accessories. To replace the handguard with a free float rail you will need to replace the front sight with a low profile gas block. I would either add MOE rail sections OR buy a different upper that already has a free float.

Great product
Just got it to the range yesterday and shot 100 rounds without any issues. Fit and finish is excellent and I would recommend PSA to anyone wanting to purchase a rifle. Great job PSA!

Poor tolerance
I have purchased quite a bit of stuff from Palmetto happily, However I put this upper on a quality lower and unfortunately it is very loose. i can see daylight between the upper and lower receiver. Also it is very "shaky" I had to use an accurate-wedge just to make this upper somewhat useable.
