Angel Custom Sentry Mock Suppressor for 16mm Threaded Barrels
(Model: Dark Earth)

"Works well on the Umarex/KSC MK23. Make sure to walk the set screw out before attaching, as it comes slightly tightened (half-set). Metal threads are good but might chew into your outer barrel, so I would recommend dabbing a bit of silicon oil or other lube onto the threads to reduce that. Otherwise lined up perfectly and looks great on the MK23. Great suppressor for the price.

"I bought this for my Matrix MK23 Falcon Beta. Added some home made foam and brillo pad discs to silence the pistol and it works great. I highly recommend this suppressor.

"It's perfect for two reasons:

-The set screw allows me to lock it down on the flat spot on the "Falcon" MK23. I believe if users made a dedicated set screw spot on their threading and never try to unscrew it when the set screw is tightened there would be no issues. It does seem loose when just relying on the threads. If you don't like using the set screw then perhaps use some teflon tape?

-The inner bore allows me to place a 31mm diameter tracer with foam spacers to make it just thick enough to make it fit perfectly, allowing me or anyone else to have a tracer option for any 16mm threaded airsoft gun. I'll write more about this in the comments as I haven't seen anyone try this.
