LRRPF52 Wrote:The performance between a 20" and a 24" is very minimal, if detectable at all across a large sample of guns when using the same gas system length. If you are looking for performance with no consideration for carrying the stick, I would go with a 24" using an extended gas system length, longer than a Rifle-Length Gas System. The main things you need to do differently for that are to have the barrel profiled so you have the gas block shoulder and journal located more forward, and get an extended length gas tube.
5/8x24 is fine on a bull barrel.
Thanks a lot LRRPF52. I hadn't really thought about having a longer gas tube. I'll be sure to have that done. I was still wanting to do a .750 gas block. This should be perfectly feasible, right?
I plan on getting it fluted as well.
Are you pretty much limited to contour options for the AR barrels? Suggestions on this front?
