Angry Gun QD Mock Silencer for MP9 Series Airsoft GBB (Model: Tightbore Barrel Extension)

"This thing is great! I wanted the other angrygun unit because it was quick detach, but it was out of stock. I purchased the tightbore extension version, and I am very pleased with its performance. It raised my FPS by about 40-50. I do run HPA, so the gun runs hotter than on green gas. The attachment involves unscrewing the tube of the suppressor, and turning the connecting piece to latch onto the 3 lugs. It then levels out, and you tighten the suppressor down. My one gripe is the trademarks when you have the rail on the bottom even with the gun does not line up like in the picture. My trades were facing the bottom. I ended up running the rail facing up 45 degrees to run a light closer to the front to give myself more visible light. Running a light on the side rail on the KMP9 works, but the suppressor does block quite a bit of the light. I didn’t test if this fits with the blaze orange paint on the barrel, but it fits great with the paint removed, and is easy to remove as well.

"Solid mock suppressor. I ordered the one without the inner barrel. Unfortunately the BBs would sometimes strike the inside of the suppressor so I ended up ordering an extended barrel. With an extended barrel and the factory bolt I was shooting 365 fps. If that is ok for you id recommend it.

"The tracer unit is good, but the internal layout of the mock suppressor was problematic for me. I installed this on a stock KMP9 and the tracer internally was close enough that the excess gas coming from the inner barrel prevented the tracer from activating. This means that after shooting I had to wait around 2 secs before shooting again for the tracer to work consistently. In order to fix this I had to move the tracer unit further forward in the included mock suppressor. This required modification, what I did was use foam to act as a washer so I could suspend the unit further forward.
Overall I couldn't just drop it on and play
Also: There was no battery included with this unit, and it takes lithium-ion batteries, not AAA. Evike sells them so don't forget to get one with this!!

"Bought the version 1 tracer but got sent the version 2. to be completely honest i hate this thing, makes my shots super inaccurate since the inner barrel that connects to the tracer is not stable at all it wobbles around inside the mock suppressor, the tracer unit itself is also not that bright. after bringing it to like 2 games i stopped using it.

"I purchased the version with the tracer included.

For starters, the attachment method is counter-intuitive. The locking collar that interfaces with the MP9 tri-lug system is independent of the suppressor body. In order to attach it, you unthread the suppressor from the collar, slip the collar over the lugs, then tighten the suppressor down again. Aside from being a bit annoying, the real problem is that the trademarks on the can are never horizontal when fully tightened, making it look a little goofy.

A much bigger issue is the interior layout of the suppressor. The suppressor body is just a hollow tube, and I'm assuming they use the same shell for all of the different versions. For the tracer version, they basically just dropped an Acetek tracer in the shell. However, since the Acetek tracer is only about half the length of the suppressor, there's a small aluminum tube that's suspended between the exit of the tracer to the endcap of the suppressor. So, in order to turn the unit on, you need to unthread the endcap, remove this little tube, shake the tracer out, turn it on, replace the tracer, then balance this little tube in place so that you can thread the endcap back on with everything aligned. Oh, and the OD of the tracer unit is smaller than the ID of the suppressor so it rattles around in there. If that wasn't enough of a headache, between the janky mounting system and the loose tracer/tube setup, something is misaligned and causing my BBs to strike the side of the suppressor before exiting, throwing off their trajectory.

For ~$125, you'd think they'd include a battery, but they conveniently forgot to mention you'd have to source your own (3.7V 10440 Li-ion btw).

Basically, if you want a tracer for your MP9 that mimics the look of the B&T suppressor, this is pretty much your only option. It looks nice (aside from the lopsided text once you screw it on), but you'll need to DIY it a bit to make it function properly. Not very impressive for the money.
