“I bought two for the M4 and one for the Aero M5. The smaller ones come with a special nut wrench but the M5 does not. It uses a standard .308 nut wrench so I was a little disappointed, but I love the handguard. The Atlas S-One handguards are BY FAR my favorite for all the ARs I own. I'll eventually convert them all over to this style.”
“Good, well made product, but proprietary. I wish AP would make barrel nuts that will accept a range of handguards. As it is I can only use AP S-MOD handguards unless I fabricate an alteration.”
