STTi USP (NBB) Silencer

Hello everyone
New replica of airsoft for me: STTi USP Match NBB version to make me the model of the movies Tomb Raider Lara Croft^^

I wanted to try to make a silent system mounted on the picatiny rail.

For the RS version, because H&K have equipped this gun with a proprietary rail I have made a remix of PrintedFirearm (thanks to him for the design) but for this airsoft replica which has different dimensions from the RS, of course → https://www.thingiverse.com/thing:3093687
