Cowitnessing questions

I have no problem with the T-1/3X magnifier combo and generally recommend it to those that only occasionally want magnification and don't need to reach out more than 300 meters.

I agree, it works fine for occasional use at intermediate ranges. More than that and I'd go with an Eotech.

Doesn't the magnifier make the 4 MOA dot of a T1 seem more like a 12 MOA at 100 yards? I thought I read this before but a quick search hasn't turned up much. I want to be able to be precise at times and if a dot covers up 12 inches at 100 yards I don't know how easy that would be.

It magnifies the dot ("blob" in the case of the T-1), but it also magnifies the target. The relative sizes are the same, I suspect.

The problem as I see it is that any shooter error is magnified at distance. You're only starting with 4 MOA max accuracy to begin with.

This is true. The magnifier magnifies every image that enters it by 3X, target and reticle, which means that the dot size in relation to target will remain constant as long as the magnifier is placed behind the optic (as it should be).

Neither part of this is true.
Shooting error is not magnified by the optic. Some shooters may have an issue due to the ability to see more wobble of the dot since range is increased though the image appears to be larger, therefore at 30 meters you will be seeing 30 meters worth of wobble though the target will only appear to be 10 meters away. What happens when the trigger is pressed is between the shooter's skill and inherent precision ability of the weapon.

A 4 MOA dot is well caipable of sub-MOA precision as long as the target is larger than 4 MOA. Molon has a good post on this proving that the precision ability of a weapon is constant as long as the shooter can provide a consistent hold.

I see what you mean...makes sense. I was actually referring to shooter error being magnified by the distance that the magnifier encourages rather than magnified by the optic, and in my mind I was thinking of a 1 MOA POA, but I can see that if the target is larger than 4 MOA then the accuracy shouldn't be affected given good shooting technique. Thanks for the clarification.

I prefer an H-1 with lower 1/3 co-wit via an LT660 mount. It's the perfect setup (for me) inside 300m.

4 MOA dot and accuracy at a distance - power the dot down.


Good luck

Thanks everybody for the great info!! Now its just age-old dilemma of getting an aimpoint or eotech
