I just wanted to take a minute to let you know how impressed I am with the upper I got from you, and to also share with you the accuracy I got right out of the box. This group was shot within the first 20 rounds using Federal Sierra 77 grain HPBT Match ammo. I’m still in the break-in period of shoot 20 clean it shoot 20 and so on. The squares on the target are in 1/2” increments. If it did that right out of the box I can’t wait to see what’s in store for the future.
