MP7 GBB not locking back
26 July, 2022, 23:38
Got a Umarex MP7 gas blowback suddenly stopped locking back on last round.
I have no idea why. Would be grateful if anyone would know.
Mags are fine - I have 2 identical Umarex MP7s. The other MP7 locks back normally with same mags.
Drop'm out with a low cap and save the environment.
