...or anybody else that might know.
Besides the profile, what is the difference between the normal 20" barrel and the M16 Gov't. Type 20in.
Is it still a 1/9 twist? I was thinking about ordering a new upper in a couple months and was thinking about having this barrel put in it instead of the standard 20" barrel.
(BTW, to avoid any pre/post ban discussion, its for a preban rifle.)
Thanks for the info! :)
P.S. - On a completely different note, what is the difference between the M16 and AR15 firing pin? Just curious.
