I'm interested in the M4 SD and got some questions. How long of an inner barrel can I fit in there without having it protrude out the silencer? IIRC the Gen 3 cylinder is non-ported, and if this applies to this SD model it would be beneficial to install a longer inner barrel to reduce the slamming of the piston head against the cylinder head right? However I don't want to install one that's too long and induce the barrel suck effect. Thanks
