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

If you need the USP 3d model go view and thanks the original designer Guillaume DETHU https://grabcad.com/dethu.guillaume-1

As this is the match version the barrel stick out the slide of the gun when you remove the compensator (useless on the replica of course) so I designed a compensator/silencer that hides the barrel.
I deliberately designed the longer front to make a cavity that will be filled with foam later on to silence all this.

I had to file the inside slightly so that it could be mounted by slightly forcing it, to allow a screwless, so if it doesn't fit on the first try, don't force it, file it down a little and repeat the test;)

Adjust the cap so that it can be easily assembled and disassembled for your foam test and then glued.

You can choose between a version with or without additional rail underneath, which you can also glue

/! Be careful it is an airsoft accessory, it should not be used on a real weapon without risk of injury /!
