Help with an Upper

[Graves]

Also keep in mind that if you're going with a sub 16" bbl, a muzzle device will have to be perm-attached to bring it to a full 16" unless you have a stamped lower.

Just get the 16" if they have them in stock or if your set on the 14.5 get a BattleComp permanently pinned on it. I have this set-up in lightweight and love it.
