AR Thread

[res]

From posts he has put up we know he doesn't.
But good point for others reading.

So for them, and not the wonderfully pedantic (to me this is a compliment) gimp

Basically both a 20" and 14.5" mil spec ar have 7" of dwell time (barrel past the gas port) as this is what the so called experts feel is needed for a super reliable AR in the hands of your average solder(read as potential muppet) during heavy field use.
In the real world of the NZ ar user less is just fine, especially if the ar has a suppresser on as this ups the back pressure and arguably adds slightly to the dwell time-smarter people than me can argue about this, I just know from experience that
A 16" cut to 14.5" will work just fine, hell, cut it to 12.5 with a can and he will most likely be fine without even having to change gas port size.
