Mr. h is schooling me on guns, etc.
But, what does "ported" mean?
I want to provide him with some more information that he didn't tell me first or tell me yet!
HA, HA, HA on Mr. h!
I'll come clean about it...eventually....HA, HA, HA!
That puff of white smoke close to the muzzle indicates porting [to me]. Porting will also reduce muzzle rise from firing, but it increases the muzzle blast and flash.
