I have one of the Monarch X 2.5-10x44SF M NP on one of my AR match rifles, very solid. I own a lot of high-end scopes, the X is very clear...93% light transmission, glass etched reticle to shrug off recoil, very nice and easy to grip1/4 click target turrets and holds zero. I will 100% compared the X with the VX3 anytime!....sorry to said...maybe even with the Mark4 3.5-10x40mm M1 or M3 model...price?....I will said between $800ish to $1000.(very resonable!). Some law enforcement agency are using the X on their tactical rifles.
I hope this helps.
