Leupold Mark4HD

Xtreme Tactical supplied my Mark4HD 2.5-10x42 scope, great service from them, delivered quickly and well packed.
I bought this scope to sit on an AR10 rifle, it's not too big and up to 10 power is plenty for me. The reticle is excellent, MOA adjustment and First Focal Plane.
Nice big turrets, you don't need to be faffing around trying to read the etched elevation, perfect.
All round a great buy from a great company.
