Caveat: Please keep in mind I have never been in combat or life-threatening situations involving firearms. I've been around firearms for 40+ years, but only recently have gotten into the AR realm. I have spent a considerable amount of time in the past year taking tactical training classes, running drills, getting involved in 3-gun and buying more stuff than I need! I've also looked at other people's setups trying to evaluate what works, what does not and why. Despite my short experience in this realm, I am a fast learner and I have no problem making authoritative statements that I will read a year later and simply shake my head in disbelief. That being said ...
I run a Swarovski Z6i 1-6x24 with BRT reticle on my 3-gun rifle (Noveske 16" Combat Carbine upper on LMT rifle length lower). I run a Trijicon TR24 Accupoint Trijicon TR24 1-4X24 Accupoint with green triangle on my Knights SR-15, which I have used for carbine classes and some 3-gun. I run an Aimpoint Comp M3 on my BCM 14.5" for HD and carbine classes. I also have two ACOGs, a TA31 (4x) and TA11 (3.5x).
First, I'll get the ACOGs out of the conversation with a few comments. I love ACOGs - bright, clear glass, nice reticles, no batteries, bombproof and lightweight for magnified optics. I've never been in combat, but I would think these would still be an exceptional all-round combat optic. However, for QCB, HD or 3-gun, there are much better options ...
Next, I'll comment on the Aimpoint Comp M3: no better optic for CQB-type shooting and HD. Fast, light, and reliable. Keep it on always and don't worry about the batteries. Just change them out every five years, four if you want to be certain.
Swarovski Z6i 1-6x24: I think there is simply no better optic for 3-gun. The clarity of glass is unparalleled in this class, and the mildot-based BRT reticle with illumination is unsurpassed for the higher precision mid- to long-range shots required in the sport. The cross hairs are not too thin nor too thick and are appropriately in the 2nd FP. Hold overs on longer shots, and wind holds, are pretty simple and quick with the reticle giving just the right amount of information without being cluttered. The illumination is there when needed, either for targets lost in dim shadow or for close-up work. The 1X setting with illumination is fast - not quite as fast as my Aimpoint or my Trijicon TR24, but plenty good for 3-gun stages requiring close up shooting. The eye box is sufficiently forgiving, but not as easy to get behind as the TR24, and I wish the turret adjustments were finer (they are 3/20 mil per click, or .54" @ 100 yards). You need a buttstock/optic mount combination that gives you an easily repeatable cheek weld so you can quickly get behind the scope and stay there. All in all, I simply love this scope - it's a work of art. And it costs as much as a work of art at $2400 or so. I was very fortunate to spend the past 3 days training for 3-gun competition with Daniel Horner and his dad (two exceptionally fine human beings). There's a very good reason he runs this scope and wins! (He could probably win running anything, but the Z6i is his first choice).
Trijicon TR24: Fast, fast, fast on CQB. I like this scope on 1X in daylight better than any. The big, glowing green triangle on a post is super fast and draws the eye immediately. The super easy eye box makes it a breeze to get behind and scan during target transitions, while that big, blazing triangle comes into alignment between eye and target. Just squeeze the trigger. Glass is bright and clear, but not Swarovski bright and clear. Reticle is deceivingly simple, yet effective ... at least out to 200 or so yards. At 300+, the base of the triangle can be used for holdover, but the posts are too thick and obscure the target. Plus, the clarity of glass starts breaking down about at that point. It can be used, but it really excels at 200 yards and in. It's lightweight and uses no batteries, which is a plus, and has a nice control for limiting light to the fiber optic. The tritium illumination at night is good, but will be washed out with a light. However, the post is easily visible in such case and is quite useable. The diopter adjustment on mine migrates counter-clockwise when shooting a significant number of rounds and needs a piece of electrical tape or equivalent to hold it in place. I've read about others having the same issue, and this should not happen on a scope in this price range. However, I think the TR24 is an exceptional value at $850 or so.
