These are all OPS INC suppressors. There was an AAC M4-2K, to try be we werent sure, and didnt try it. The guy who makes OPS cans told me it would work, so I knew if I damaged one it would be replaced. I’m not sure I’d be able to contact another manufacturer out of the blue and ask for a free replacement because I blew up the can shooting it full of water[BD]
It ABSOLUTELY makes things quieter, and I was amazed how many shots the water lasts.
An OPS Inc. suppressor can be removed almost as fast as any of the highly touted “QD” cans on the market. I can’t think of many instances where one would need a suppressor removed in 2.5 seconds because 5.0 just wouldn’t cut it…
Somewhere I have video of Steve threading one on and off. I’ll see if I can dig it up. Suffice it to say that the time differential from the OPS to a QD hasn’t been enough to sway me toward the QD competition.
