MP7 AEP Making wierd revving noise after shooting

(1/1)

hello:

Mp7 is making weird revving noise after cycling. Know what this could be or how it could be fixed? PS. I know it sounds really grindy while shooting but its not really that bad in person. Its just the revving im worried about.

Sparky D:
Sounds like a busted Anti-Reversal Lever or ARL spring

hello:
are TM Clone AEP gearbox parts compatible? I have a spare DE USP lyign around. would the AR Latch fit in the mp7?

Sparky D:
Pistol and SMG gearboxes are not the same, and I'm not certain on whether the ARL or spring would be compatible.

Odds are it's the spring that's broke, though.
You'll need to open it up to be sure.

infected:
Sounds like a broken ARL like others have said.  WELL mp7's are compatible for the most part, although sometimes the specs are a bit off from a TM.  I have dropped a complete Well MP7 gearbox into a TM body and it worked but took a good bit of fitting to get it to work properly.  If you can't find a replacement ARL let me know and I can dig through my parts bin and I'll see if I have a spare since I have a WELL mp7 here that was gutted for parts.
