Angel Custom FPS Reduction CQB Valve for KWA KSC MP7 MP9 M9PTP Airsoft Gas Blowback Series

"great low cost option for the complete low power bolt. Very easy to install and nets just under 350fps with .20, with room temp gas mags. if you have a KMP9 and plan to play CQB with it, definitely pick one of these up.

"Works perfectly. Was at ~400 on my Umarex MP7 and went down to a very consistent 345. Installation is easy if you know how to disassemble a GBB. Works great and is way cheaper than the CQB bolt they try to sell for $45 (which is the normal bolt with one of these dropped in, from what i hear)

"Used this in a kwa mp9 and it reduced the fps from 400 to around 325 with .20 bb's. Relitively easy install if you're comfortable disassembling gas blow-back bolts. I suspect this will fit most kwa guns with a rocket valve, it's the right size to fit into my akg-74m as well

"Works like it should so I won't give it less than it deserves.

Dropped my FPS from a max min of 390-350 to 330-300/299. Good for most CQB arenas but unfortunately not mine since my CQB arena is capped at 300 for full auto pistols like my M93r. So it works just not well enough.

"Bought this for a KWA M11 NS2 wondering if it would work; Confirmed. This does work in the M11 as well. It reduced my FPS way too much though. But if I get an extended inner barrel I may need that FPS reduction to stay under 350.

Looks like there is some compatibility between the Mp7/Mp9 and the M11.

"Did what it is supposed to...make your gas gun set for CQB. Put this in my KWA KRISS and it dropped it down from 380 to 280 so much more than I wanted it to. +20 FPS when I filed a bit off and polished so up to 300. Would like it more if there was solution for the sweet spot 330 for local indoor play. Maybe a bit more adjusting and I could get it there. Really happy with the suppressor Angel made for the KRISS...now if they would come out with a drop in full CQB bolt for the KRISS so we could easily swap in 5 min with no tools. I would buy that so fast!

"I had traded my AEG with someone for a KWA LM4 because I wanted to get into the gas gun world but a tight bore barrel was installed making it too hot for my local field. Installing this into the bolt dropped the FPS from 450 with .20s down to 350 making it field legal in CQB. Great product with pretty easy installation but it dropped the FPS a lot more than I thought.
