I have the Vortex 1-6x ii-e (VMR2-MOA), the Leupold VX-6HD Multigun (CM-R2), and the Steiner Px4i. Here's my thoughts after using all of them in our local multigun and black rifle matches:
VX-6: Had this one the longest. So far neither the Vortex or the Steiner has been better.
Bad - It has only 2 faults:
not daylight bright dot
built-in throw lever.
I lost two of the standard throw levers on that scope ... and they were torqued on. We use dump barrels in matches and I saw the second lever in my go-pro video on the ground the week before SMM3G. It hit the side of the barrel and came off. I bought a switchview and solved that problem. I will say that you could go without a level like some of the USAMU team and be just fine - the zoom knob is smooth on that scope. Not really a negative vs the others because you'll still pay more for a throw lever.
CMR2 is not Daylight bright ... so I just leave it turned off when shooting. I did use it one time when we had an overcast day and it was nice. I asked one of the national champions here that is sponsored by Leupold about this - he was using an older VX-6. He said he never found illumination to help beyond 50 yards and the more I have used a dot, I agree. After turning on the dot on the vortex to full power and trying to shoot a 6" plate at 380 yards and not being able to see the target through the red dot, I realize he was right. The dot is nice in close range blasting, but not a necessity.
If Leupold were to offer a daylight bright reticle for this scope, it would be the perfect 3gun scope. I'd probably only use illumination on close blaster stages, but it would be nice to have.
Weight - best by far in this class
Eyebox - best by far ... it's noticeably better than the Vortex. I have more motion side-to-side and can get closer to the scope without a tunnel vision
Turrets - I like being able to use these. I can change zero for my two loads and they lock in place
Reticle - this is the ideal 3gun reticle. It matches my long distance ammo nearly perfectly and I REALLY like the numbers next to the hash showing distance. The circle makes it easy to see paper and close-in targets - not as well as a red dot, but still pretty good.
Auto-off time/auto-on motion reticle illumination ... even though I don't use the illumination, I turn it on before storing it just in case I need it at night. Every scope and red dot should have this feature.
Love this scope also ... just the standard 3 things that you already know as negative: weight, weight, and weight.
I bought this because every forum and review said it had the biggest eye box, but that isn't the case for me. It's big enough for 3 gun - I've shot this in 3 multigun and 2 black rifle matches and haven't had any problem finding the targets due to eye box blacking out on me.
Red Dot is very nice - makes it easier to call your shots on close paper when you are going fast.
I got the VMR2-MOA only because the reticle matched nearly perfect with my loads - the first hash is 310, 2nd is 400, 3rd is 495 ... so 300, 400, 500 easy.
In the match yesterday I actually forgot to turn the dot on for the stages with long range targets and didn't feel like it was slower. In fact, one of the stages had 9 IPSC paper and it was easy to call shots ... the red dot would have helped but it didn't slow me down.
Great glass - almost as good as the two above. Price is the best reason for this scope - low enough price and good enough glass. It has daylight bright dot. The reticle is great although doesn't match my long distance loads perfectly, it's close enough to get on target. Weight is good enough also.
I used this for a 3gun and a black rifle late last year. It was fine on the 3gun stages out to 300-400 yards with bigger targets. The black rifle match had a dark blue painted target in front of some green bushes and I just couldn't pick out the steel at 4x. It worked great for the black silhouettes and plates at about 200 yards.
Someone else mentioned the c-more scope with the discount code. That's probably the best deal I've seen. I haven't shot the scope in a match, but I spent some time dry-firing it. The guy who showed it to me unapologetically calls himself a "glass snob" and uses Swaros and every other good scope you can imagine. He told me the C-More glass is as good as Swaro. If the TJ reticle worked better with my load I would have bought that instead of the vortex and saved $500. If you run a 55g bullet it's a very good option for the price. I'd still like to get one of these ... maybe some day.
If I had to go with 1 scope, it would be the VX-6. Eyebox is the single most important factor for me and that one wins. weight is my second criteria and it wins there. If there were a daylight bright dot in the middle of that CMR2 reticle, it would be perfect for 3gun.
