I am about to acquire an armalite AR-10.....I need some advice

First of all I have always liked the A2 front sight post but plan on shooting this suppressed and don't want blowback

If I decide to keep the front sight post can anybody suggest a reputable forearm that has a gap for the Front sight post something on the 15" range?

If I want to add an adjustable gas block what would you guys recommend - I have heard great things about JP.....I think they even make a A2 front sight post that is an adjustable gas block
