Airsoft SRS-A1 picatinny rail

There are many Picatinny rails on this site. I made this one from scratch in Tinkercad and specifically shaped it to fit the screw holes under the handguard on the Silverback SRS-A1 Sport model. It may directly fit the other lengths as well.
The unsupported portion of the rail extends all the way back to the trigger guard and allowed me to mount an angled foregrip where I wanted it. I had to do a little bit of shaving/filing to make a tight fit after printing.
