update
The TRS-26 sight came in today. Got it mounted at the rearmost slots and familiarized myself with it. Oddly it didn't come with a user manual, and I didn't know which end was front or back and why it didn't have a red dot LOL Looked up the user manual online and got it all figgered out.
I went out last weekend and got the Magpul sights sort of dialed in. The rear sight is blurry with bifocals, and I can't hit much, so I call it good after 30 rounds and a few adjustments. Looking through the red dot sight, it seems it might be a cure for my vision woes. Oh, the rifle performed flawlessly with the M855 stuff. One gripe, the adjustable stock pulled some hair out of my face a couple times. :)
