Love the handguard and upper combo! - Aero Precision M4E1 Upper Receiver and KeyMod Handguard Combo, No BCG/Charging Handle

Made my latest, .300 BLKOUT upper build quick and simple. Just mount your gas block, insert the barrel, screw and torque the barrel nut (no need to "time" anything for the gas tube) and screw/torque the 8 set screws to secure the handguard directly to the upper. That is it.

Fit and finish is just what you'd expect from Aero Precision; perfect. FDE Cerakote is expertly applied.

Bought a 9" handguard and an 8" barrel and installed a Silencerco Trifecta ASR muzzle device. My Omega 30 suppressor nests about an inch inside the handguard nicely.

Any and all AR's I build in the future will use this upper/handguard combo and Optics Planet will be the first place I check for them too. As of May 2018 O.P. had the cheapest price on this combo anywhere, including the vendor's own site.
