"New Wave" Small Rice 7 (MP7) Review

Recommended Posts

Old WE GBBRs such as the MP5/MP7 had overly strong rocket valve springs and recoil springs.  Rocket valve springs can be chopped by  1.5 rungs while recoil springs can be chopped between 30-40%.  That will increase the efficiency.

 

And no its not the #049 that eats away at the bolt, it is the hammer.

Currently I have the issue of the gun freezing fast. You can feel the gun shooting weaker one-by-one until it just spews all the gas out. 

Maybe first-gen mags? (the ones with lower gas routes)

Nah. I switched those out as soon as I got it.

Then it's either a worn out nozzle to bolt carrier oring, or the nozzle is disconnecting prematurely from the bucking. That should be easy to check for, just pull the charging handle and see if it stays coupled to the chamber for a couple cm then snaps back, or it just wants to follow the bolt carrier
