Does anyone make a thread extender? By that I mean something that will have 14mm CC threads about 2-3 times longer than the usual tapping on the end of a barrel?
Basically I was thinking about mounting a velocity reducer inside of a silencer. Most silencers allow you to take off the end cap where the threads are. If you could screw the end cap on first, then still have about 1cm of threads still left above the end cap, you could screw on a velocity reducer and then put the suppressor can on top of it all.
And because I am at work (and terribly bored), all I have to work with is MS Paint so bear with me for my awesome MS Paint diagram to demonstrate what I'm talking about.
