PSA Mk12 Upper

Haven’t seen much about the PSA Mk12 14.5 uppers so I decided to buy one and see what ammo it likes.

Build:
PSA 14.5 Silencero ASR P&W
Silencero Velos 556k
Atlas bipod
Athlon Ares BTR gen ii 2.5-15
PRI recce top rail Mk12 Mod H

The first group was the initial zero using Winchester WB 55GR.

The target on the left is a 10 round group at 100 yards using Hornady Frontier 77GR OTM (FR262).

The target on the right is a 10 round group at 50 yards using Hornady Frontier 75GR BTHP.
