"Gotta say....This suppressor is niiiice.
2 14mm and - adapter, 16mm built in and the two portions of the suppressor itself, one portion having the 16mm threading, the other as the longer tube.
The build is an aluminum alloy and carries some decent weight to it but still pretty light. The INSIDE IS HOLLOW BE WARY, it shouldn't affect your bb's that much as long as you don't shoot into the suppressor itself with a too low/too high hopup. You can buy foaming if you want to actually fill up those gaps in your suppressor and actually help it muffle sound, which is what I did. It comes in two pieces, the first bit being the longer darker suppressor portion with a vent holes at the front of the suppressor, and the second portion which screws onto the first portion and can also take adapter threads.
For me this is the part where I have to take one star off. First, the threads will get stuck very easily in the 16mm base threader so make sure you know which is which before you start screwing them in. The grey washer will be the 14mm negative, and the black one 14mm positive from my experience. I purchased with my G AND G RAIDER CQB and it's quite easily able to adapt onto it. You can get the front sight adapter kit from AirsoftMaster and it's VERY easy to tech on, they have an entire walkthrough tutorial guide if you're unsure about it. In addition, just because it was my gun, the CM16 i believe has reverse threads for some odd reason on the adapter kid (left to tighten, right to loosen), so the adapter 14mm worked, but it was a little harder to get on my 16mm original thread, since it tightened right, not left, so I'd have to tighten the suppressor to just the right extent so it didnt loosen my 14mm threading, but still made sure my 16mm suppressor was on good and well.
I foamed my interior with some foam for sound stuff. NOT ILLEGAL I SWEAR :) Just don't actually use it on a real gun/"brandish it" so people dont freak out. You really have 3 options for foaming, either buy cymbol acoustic foams, which already come in circles, buy some normal acoustic foam and cut it out, or buy a foam pool noodle kinda tube with the same diameters as the suppressor and just stick it in there. Pretty easy overall.
All Adapters included and works.
A little hard to use
overall 4/5 would use
