It just clips over your standard A2 type flash hiders like the ones on standard M4's - pretty sure it even comes with an A2 type.
Similar to those KAC suppressors everyone has.
So give or take if your inner barrel doesn't go past your flash hider as it is you should be alright.
I was looking at picking one up myself but it really serves no purpose in airsoft other than cosmetics and I decided a short stubby suppressor of similar size would at least give me that 'thump puff' noise.
