First and foremost: I am not the designer of this. This was originally posted years ago and the files appear have been deleted years ago, as well as the designers account. In addition, this file appears to be corrupt, at least when attempting to edit it in TinkerCad. It does, however, appear normal and slices just fine in slicers, and will print fine. There have been issues reported of this design, mainly noted as being fragile and having too tight of a bore if not perfectly concentric.
Reports of performance when tested have been very favorable audible-wise, as well as flash suppression, FRP, and backpressure (it is just for 22lr, after all)

DO NOT use with anything more potent than standard 22lr, such as even just CCI Stingers on a pistol length barrel will grenade this. Let alone 22mag and heaven forbid 5.7, otherwise you'll have wasted your time and money in a single round in a somewhat spectacular fashion.
