I've been brainstorming a mid-length upper build. I really like the Noveske N4 but it doesn't come in mid length gas system or a 16" barrel which is a deal breaker for me. I want to build a top-tier reliable carbine though and this is what I've come up with. Tell me what you guys think.
Upper: LaRue Stealth/ DD 10.0 lite rail/ PRI Gasbuster
Bolt/carrier: FN contracted BCG
Barrel: Dennys 16" mid-length Operator w/cut down FSB
