I'll be changing the name of the topic after I get my approval because there is so little that I can do in the meantime other than the planning stages, but I wanted to start the topic keep the information together so for now, this title seems appropriate. This will be my fourth suppressor build, and is likely my last. I am using everything that I have learned over the years, or thought I know anyway, in hopes that it'll be pretty effective. I am going to incorporate several proven design features, such as reflex porting over the barrel. And perhaps even porting the barrel directly into the reflex portion of the suppressor if my expansion chamber design doesn't perform as I expect or hope. But most of that is going to have to wait until the government clears up it's 8 month plus backlog of submitted paperwork. Until then, all I have to show for my ideas is turning my barrel down so it will accommodate the reflex portion of the can, and I also cut back quite a bit of the heavy barrel behind the gas block for nothing more than to reduce weight to mitigate some of the added weight of the can. While a few ounces may not sound like a lot now, every little bit is going to help later.
