Kral Quiet Kit

[thammer]

Ported Kral threaded barrel cap with o-ring allows air to enter the back of the shroud where the stock end cap blocked it. Still leaves room for 3 Marauder baffles, a tension spring and the original shroud cap with an air stripper.

Could you go into more details on what you did, I get the gist, you are allowing exhaust gas to escape from the back of the shroud but more pics of the assembly would be appreciated.
Thanks thammer
