Aero Precision Atlas S One 16" Upper M4E1 lower 

I have the same general set up in black. My barrel is 18".223 Wylde. Aero Precision is goo0d to go.

Very nice rifle, thanks for the excellent show and tell. Aaand, I agree with you about Aero Precision products.

Hey Erik... Very nice build sir. I too recently build one from Aero Precision upper/lower, with the Clint Smith's Thunder Ranch Special Edition version in FDE also. I also went with the Atlas S-One handguard because it's lightweight and I have smaller hands/shorter fingers. It fits like a glove in my hands! Although, I went with the CMMG 350 Legend barrel, Cryptic Coating bcg, a Rise Armament LE145 Tactical Drop-In trigger, a Radiant Raptor charging handle, and it runs like butter. I also paired it up with a Holosun 510c green dot and a 3X magnifier. I can't wait till this up coming MI deer firearm season.

Fde on mines is a little off, but nice handguard

Has that in force light give you any problems?

Being at an indoor range, were you free standing shooting?

I have an Aero Precision in 350 Legend with a 20" barrel. Shoot 180 gr Winchester
