Budget .223/5.56 "Precision" Upper?

[Bellycrawl]

I purchased a larue 5.56 UU. With Hornady frontier 68 gn and 75 gn, it’s a .8” gun. The 75 gn ammo is at 2655 fps. Frontier is not match but it shoots well. I have some 77 gn BHM 5.56 ammo, but I haven’t shot it yet.

Any specific questions?

Blessings.
