About this model

Airsoft M4 HU chamber, created by GrabCAD user Szilagyi Laszlo. I ported model to STL files, so its easier to prepare print. Im using it with r-hop and it works really well. You need also M2 bolt, to screw hopup arm with chamber. Yes I know there is same model on Thingiverse, but the STL files are little angular. My files are better.
