Here's a build from last year...
And it's maiden voyage out to the range to sight it in...
In case anyone is wondering, here are the particulars:
Aero Precision - M4E1 stripped lower, lower parts kit minus FCG/trigger guard/pistol grip, buffer kit, M4E1 threaded stripped upper, forward assist & dust cover, nitride BCG, charging handle, ATLAS S-ONE M-LOK 15" handguard, low profile .750 gas block, VG6 DELTA 556 muzzle device
Ballistic Advantage - 18" Premium Black Series .223 Wylde SPR stainless steel barrel
Rise Armament - Rave 140 flat trigger
Holosun - HE510C-GR open reflex green dot
Magpul - ACS-L stock, MBUS front & rear sight, PMAG 30 GEN M3 mags
VZ Grips - Alien grip and rail panels
Spikes Tactical - melonited gas tube
While it certainly doesn't have any high end components, I've had zero malfunctions, it shoots like a dream and is just what I was looking for.
