stock bolt on the kwa mp7 shoots >400 fps in 25C sunlight, mine shot 450+fps with .2s

With the cqb bolt, in my 15Cish basement it shot 300 fps with .2s... in that same 25C sun it shot 360-370.

The npas is ok.. but you have to reach the tool down the barrel to adjust it. risking scratching the barrel bore. The bolt takes less than a minute to change, it's 2 pins, the whole back of the gun comes off, bolt comes out... put the new one on, hook it into a little loop slide the whole thing in, pins back in and ready to go.


Mags get heavy though and having to carry gas and BBs makes it a bit more cumbersome to skirmish. slower paced milsim might work out better, but it's not as consistent in temperature fluxuations as an AEG...

at a game like nightfall last weekend my mp7 would've been shooting 370 during the day but at night when temps dropped to 15 it would shoot 300... and hopup would be tuned to the heat of the day and the ammo I'd be using during the day... so if I used .3s then at 300 fps the bbs would be super slow and drop a lot more due to loss of fps. You have to constantly adjust to keep it consistent where an AEG is just set it and shoot.

Then again, there's nothing more terrifying than a battle cry accompanied by a screaming clacking bolt of a gbb indoors.


as for the xcr and masada, I believe both are v2 gearboxes, so neither would have an advantage of ease of disassembly. V3 is easier to take out of the gun, fewer screws and slightly easier to work in, v6 imo is the easiest to take out and work on, true v7 is apparently a bitch to work on.
