Re: Most Durable Optics.
I have always liked the ACOG. Its not the best in the sense that it isn't variable. But they are built to last. I had one on a M4 going on 4 years, and there was never anything wrong with it. You have to remember its just an Advanced Combat Optic Gun site. You set it, and forget it. At least that was my experience. I zeroed it once and left it for over a year in Iraq and it never shifted zero.
As to durability, I don't know what hewlett260 is talking about as I've never even heard of that many failures. Let alone in one battalion or company. When I was in, that was the optic you wanted. I don't know how many times my rifle bounced around in a hum v, striker, mrap, or got bumped or hit or dropped.. and it always was zeroed.
But now that I'm out I don't feel that I need a combat tough optic on my rifle so I'm thinking I'm going with a Vortex PST 1-4. TO ME they seem durable enough for my needs. Be it hunting, 3gun, or general plinking. Oh and don't forget when the SHTF.
I think you would be well off with any of the scopes mentioned so far in this thread. It all depends what your going to use the weapon for. Is it going to get dropped and chucked and drug threw crap/ Or is it going to the range, the field, and maybe a comp?
With that said.
-Nightforce
-ACOG
-USO
-Schmidt & Bender
Are going to cost more, but probably be the most durable.
-Vortex
-SWFA
-IOR
-Nikon
-insert economical priced scope brand name here
These are going to cost less, wont be on the same level. But as long as you dont shoot at it, blow it up, use it to pound tent stakes in, or hand to hand combat with it. You should be good. Hop on SWFA.com and look at IOR Valadada, Vortex PST and the Razor series. Theres some below $1000 and a few just over $1000.
Best of luck
