Not sure if this would be better in the optics forum, but this is specifically about a setup I'd like advice on with my M6-SPR.......(Mods, please move if this needs to go in the optics forum ) *Disclaimer* Please don't fault me for thinking in a worst-case scenario concerning this, or how I always think "tactically". It comes from my job, and the way the Infantry has "raised" me since I joined at 17 years old. Ok, here goes- I bought an EOTech 553 for my SPR...........loved the way the SPR felt, balanced, and all else.....it is actually lighter than my long-range dedicated M6A2 DEA, so I decided to make it more of a close-quarters to medium range rifle. Well, I want magnification now, but don't want an ACOG. I'm dead-set on either the Magnifier, or the Leupold Mark 4 CQ/T. This is the monster that is actually making my brain have to function while I'm on Post-Deployment leave. I'm considering two different routes- Course of Action #1- Buy the Gen 2 EOTech magnifier and mount it behind my 553. Pros: - Won't have an optic just sitting around waiting to be used.... - Uses the same batteries as all my other stuff on my two ARs- CR123s - I'm not gonna lie; I think the whole "flippy" thing from close quarters to medium range is cool. - I've used the 517 and Gen 2 Magnifier while overseas; albeit for a short time. Cons: - I'd have to mount the EOTech further forward, which means when it came time to clean the piston after shooting, I'd have to take the EOTech off to take off the top rail cover to access the piston, possibly losing my zero, although the ARMs mounts are *supposedly* a Return-To-Zero mount. - If my batteries go "ka-plunk" (shame on me for not having extras), I have nothing but BUIS. - I'm trying to keep things light: total weight of the 553 and Magnifier w/ mount is 24.7 ounces. - FTS mount could possibly take a crap, and break. - You have to press buttons to turn it on to put it into action. Course of Action #2 - Buy a Leupold Mark 4 CQ/T 1-3x14 http://www.leupold.com/tactical/products/scopes/mark-4-cqt-riflescopes/mark-4-1-3x14mm-cqt/ I played with one of these at my local dealer for about 30 minutes, and even mounted it on a rifle, and loved it. Pros: - One self-contained unit; rail system less cluttered; more streamlined. - Uses common AA batteries for reticle illumination - Reticle is etched, ala, ACOG, so if batteries die, I still got a reticle. - Goes from 1x to 3x magnification, simply by turning the eyepiece. - No buttons to activate, or play with; no need to turn it on to use it, unless you wanna use the reticle illumination. - This is a big one- don't need to take it off to clean my rifle. - Lighter than the Eotech/Magnifier combo. CQ/T is 17.5 ounces, as opposed to 24.7 for the combo. Cons: - More expensive than the Magnifier; by about $250. - I'll have a spare EOTech just sitting around if I buy this; maybe I can mount the Eotech on my 870 and play around with it.... So, with these things outlined, what advice can you guys offer me? I'm dead-set on either the Mark 4 CQ/T or the Magnifier/EOTech combo. What am I overlooking concerning making this decision?
