Couple hundred round review - Aero Precision M4E1 18in .223 Wylde Complete Upper Receiver with Flash Hider

Run mine with a rifle buffer. Out of the past 2-300 rounds, I had 3 failures to feed with 55 grain 223, which i would say is more due to the ammo then the gun itself. I can get about 1 moa with my bipod running 55 grain. Overall for mine I like it, only downside is with the regular heavy barrel she is hefty, but havnt had issue with poi changing with heat yet. Dont run her super hard or fast, but hasnt really left me with any complaints I cant blame on ammo I bought during the pandemic.
