The 0.2l pack is too tight for the stock.. o had too punch for the tank go inside..And to remove i need to give hot air .. not too good in my opinion.

Mounting problem
The G&P R3 stock does not work with the UGS, the bittom pin does not enter on the hole of the UGS rail. I think that the problem is that the 0.2 L hpa tank hits the bottom part of the G&P stock.
