Airsoft SRS-A1 picatinny rail

thingiverse

I made this Picatinny rail from scratch in Tinkercad, specifically shaping it to fit the screw holes under the handguard on my Silverback SRS-A1 Sport model rifle. It may also work with other lengths of the same type of firearm. I designed the unsupported portion of the rail to extend all the way back to the trigger guard, which allowed me to mount an angled foregrip exactly where I wanted it. After printing the part, I had to do some shaving and filing to get a tight fit.
