"Works great in my WE-Tech M9 Beretta for lowering the FPS. No problems in ~6-7 sessions so far.

"Installed this in the WE M4A1 Open Bolt. It's great. Wasn't a hard install. (Thanks to a YouTube video by a guy in Britain. It has no included instructions.) Took about 20 minutes to a half hour to install, with just a couple of standard tools. Was able to adjust FPS down to the high 200s with .25s so it was legal at my local indoor venue. It also stabilized the FPS, bringing it to a variance of 15 FPS between shots from the previous 40 FPS variance.

"Works wonderfully on the WE AK-74UN(AKS-74U). You can adjust your FPS to coincide with your field limits.

You must modify the rear half of your nozzle in order for this to work correctly. Basically it involves shortening the nozzle by a bit, this is easily done with a dremel or another rotary tool.
