new scope

[Vepr62]

OK, I bougt new upper for my registered Bushmaster lower. It is a flat top receiver (never had one before) and fixed front sight. Would this A.R.M.S.#40 http://www.mountsplus.com/miva/merch..._GAS_BLOCKS/40 rear sight work with it?

Did anybody use this scope on your rifle? http://www.grsc.com/combatriflescope.php What quick detach mount did you use for it? What rings will place it above the front sight? Thanks.

The ARMS 40 will work great would your upper. I have something similar. I would recommend an EoTech or an Aimpoint, or even a Trijicon ACOQ if you want to spend a little more for your flat top upper. Spend a little more and get something that is military proven.
The GRSC looks good, but if you're going with that route, check out the Trificon Accu Points or Leupold has a Mark 4 CQ/T scope that looks and works great.
