Ok.. last year built my first lower, and bought a complete upper.. This year I'm trying to build my first upper... working on getting all the parts together... you all had such good advice on the lower build, I figured I'd ask again about the upper build. Just waiting for a few ordered parts to come in

Bolt carrier group
charging handle
so... using a Strike Industries dust cover made that extremely simple as it has a spring loaded pin. The AERO upper has a threaded forward assist pin to make that easy.. The barrel has an indent on the bottom to line up the gas block screw. Seems like it all goes together pretty straightforward... no springs to lose. LOL
anything else I should really be aware of? TIA
