The reason I don't run a 16" DMR is because my 10.5" MK18 shoots just as well as any DMR.
As far as "pushing" .30s or .32s, you can just use a ported cylinder for a slightly longer barrel and maintain steady muzzle energy between .20s and .32s on a very short barrel. Or you might even get a bit of joule creep.

TC was this the gas for AEG exclusive, or did it apply a bit to GBB's?
