Anyone here have an EOTech on a .308?

I've heard hear and there that the EOTech's can have problems mounted to higher caliber rifles... anyone have one mounted to a .308 or larger caliber that can attest to their durability?

I had an Eotech clone mounted on my R-25 in .308. It didn't have any problems but was only on there for 100 rounds or so...

Thinking about mounting one on the G3?

Yeah, I'm going to be welding a picatinny rail to the receiver finally as well as some other changes so I can mount optics on the rifle. G3's are a nightmare for optics because of that damn stanag claw mount. So this will finally remedy the situation and make the rifle useful.

I would think that the EOTech wouldn't have any problems on a semi-auto due to the recoil/buffer systems.

If this were going on an AR-10 I wouldn't have even bothered to ask, however a G3 doesn't absorb much compared to an AR-10. The bolt assembly weighs a considerable amount - I've went through a number of red dots on it already. I remember someone telling me EOTech had a separate version for .308's but I'm not sure if that was true or not. But, if their warranty would cover it, it doesn't really bother me too much.

Call up their customer service and ask. I didn't realize there was that much difference between the AR10/G3.

Early G3's/PTR91's had no recoil buffer at all. The AR-10 BCG is less than half the weight of a G3 bolt group, and I can attest that is a substantially higher recoil on a G3 than an AR-10 just because of the design. I can't shoot more than a few mags through it before I have to put it down. It's one of the things I never really liked about them (and most people). Because of that it's been an optics cookie monster. As long as the EOTech warranty will cover any damage, I wouldn't think twice about it.

Everything I have read hasn't said anything about what caliber you should mount the EoTech on. I would think it is fine on a .308 but I would call them to check and be sure.

I honestly can't see how the hell anyone can shoot over 100 yards with an EOTech, the damn reticle center dot is the size of the bulls eye at 100 yards.

I know, it is supposed to be 1 MOA or whatever .. I think it is closer to 4-6 MOA in size. I know that I am going to be selling my EoTech soon and going with a Aimpoint Comp M3 in the 2 MOA flavor.

I'm interested (again) in getting that from you... that would be fine my G3 I think.


..and help you fund that aimpoint.

I have one on my AR-15 and you're right, at 100 yards, the 1 MOA dot covers a lot of paper.

However with that being said, I still enjoy having it on my AR-15. at 100 yards I can hit the target about 98% of the time. If it were a man sized target, every round would be in the torso. For 1 MOA shots, you really need a scope with at least a 9 power magnification at 100 yards.

The same would go for an Aimpoint.... Both models you're gonna need their magnifier to shoot farther than 100 yards. Maybe you should look at the Trijicon sight.
