Re: Scoping a Battle Rifle (308)
Yeah, US Optics are the heaviest scopes I have ever handled, though. I know for a fact looking at numbers that several of the scopes I was referring to are lighter than several of the ACOG models. Perhaps weight was not the fairest complaint, though, because I was not taking into account the necessary weight of the mount. Sorry. I stand by the rest of what I said, though.
By more versatile mounting options, I was referring to the fact that you can put scopes in rings. Try mounting an ACOG on a FAL, AKM, or M1A (look at the top of page two) and getting proper cheek weld. There are many more options for rings of virtually any height, as well as various cantilever mounts and other specialty solutions. The ACOG is not quite that versatile. (that is another reason I prefer 30mm Aimpoints to Eotechs, but whatever)
The eye relief on ACOGs IS horrible. I'm glad for you if it does not bother you, though.
I think the biggest benefits of 1-4s over ACOGs is the variable power (essentially you get a better end setup than an ACOG with an RMR piggybacked) and the reticle and turrets. BDC reticles have no place on a rifle that you want to have any kind of long range precision role. It *may* be dead on with one particular load at one particular altitude (forget all the other variables), but that does not allow you to have accuracy when those things change. A good mil reticle that you have used enough to plot out can do everything that a BDC reticle can do, but a BDC reticle is not nearly as useful as a Milling reticle.
A lot of people with a lot more experience than I adore ACOGs. That's great. By all reports, they are insanely solid and a very nice company to work with. However, I maintain that I don't see much of a need for them with all the 1-4s, 1-6s, and 1-8s.
