Crosman SBR Silencer

thingiverse

Purchased the Crosman DPMS SBR air rifle and absolutely love it. Full auto, CO2 powered fun is what I get every time I use it. The rifle breaks down very similar to a standard SBR, so I decided to start making some parts for it myself. I don't know why I think I can design uppers, lowers, etc for it- so I'm going to do just that. I wanted to start simple, though- and as such... we have the suppressor attachment. This is not a real silencer, it's just a mock-up attachment for visual effect only. Designed it in Fusion360, and this was a real quick design project. The threads on the end of the Crosman are left-hand, so it took me 3 or 4 tries to get the correct thread pitch, etc... but I successfully matched it perfectly. Will post a photo of the finished product once it finishes printing, I just wanted to go ahead and get the model posted for now. Edit 1/29/20: Printed beautifully every time. I printed the model at 102% to make sure that the threads would work properly, and it was snug and perfect at that size always. Planning on reprinting in a black finish and adding some effect paint, will post pictures once it's done completely. Also planning on designing another version with coarser knurling and possibly less of it with some flutes included. Another thing I would like to design is a functional version- not that an air rifle needs much silencing, but it might be fun to try. Edit 1/31/20: Added another model with less coarse knurling today. Edit 2/18/20: Added another model with slight offset after barrel but before suppressor. Added some pictures of my final product with "wear" and a matte finish. Actually printed in black, but sprayed a matte black on top, then applied a silver paint to make it appear to show metal wear marks. Turned out really well every time I looked at it.
