My First Grendel, barrel recommendations in 18-20" please.

[ricsmall]

cant answer about the gas block. But I think I remember reading that an 18" w/RLGS would be more reliable. Maybe Bill A. or some of the veterans will chime in. I do know that the 18" w/MLGS is slightly overgassed,as per Bill A. If u want the gas block covered on an 18", youll need to go ML so a RL handguard will cover. That is, if you prefer a little more barrel exposed. Personally, I like 6" or more of exposed barrel. MAkes for a more balanced look,if that matters. PRI makes a LP GB that is Adj., and it will fit under a normal dia HG.

Edit: I had it backwards apparently after reading Mr. A's post. thanks rasp for clearing me up.
