Awesome product - JMac Customs Taper Mount Suppressor Adapter

It adds almost no length if any at all compared to direct thread. Make sure you use a cherry bomb or similar length, for me it was compatible with the cherry bomb, the Rearden 3 prong flash hider and the regular bird cage Rearden flash hider. I installed this on a scythe STM and like I mentioned, it added such a tiny bit about of length if any compared to the direct thread mount it came with. Looks flush at the mounting point.
