Jack E on Jul 15, 2019

Can the muzzle device be removed & a suppressor installed instead?
JumpmasterC on Jul 15, 2019

PSA when are you gonna make an AR9 maurader with 7” barrel?
Justin S on Jul 31, 2019

Would you be able to swap out the handgaurd?
kurt s on Jul 17, 2019
BEST ANSWER: im sure you could take off the delta ring and flash suppressor and put a free float rail on it and a new suppressor but why would you want to buy this when they already make what you want only .5 of a inch longer for a lot less then your going to have in it swapping parts.

Can I use 'S&W MP15 s2 5.56' bolt carrier group on this upper?

If I remove the muzzle device how wide is that opening? I wanna take it off and replace it with a suppressor.

Quality, Dependable, very practical for vehicles and or home defense.
Solid gun. I also have the Marauder in 5.56, I was very pleased with it and when I saw PSA come out with the .300AAC, I had to get it. It stays beside the bed.
