red dot MOA

[thecircus]

I know what MOA is but I have no idea what it is refering to on red dots. Is high MOA better? Say I want to buy a 30mm red dot and there is one with 4moa and one with 7.5moa, which is better?

[CRUSHER]

MOA refers to minutes of angle
roughly an inch at 100 yards
A 4 moa dot will cover 4 inches at 100 yards
A 7.5 will cover 7 1/2 inches at 100 yards

which is better?Crusher is spot on .... but which is better depends on your application.

I use these deals on handguns and carbines ... quick target aquisition is a big bonus. However .. accuracy, whilst pretty good, will rarely match that of a scope with good cross hairs.

I favor the 3 to 4 MOA dots .. smaller the better for me but .. bowling pin shooting for example could well benefit from a larger dot.

[thecircus]

what exactly do you mean by cover? Are you saying that a 4 MOA dot will appear to cover up 4 in. of the target at 100yds?

[P95Carry]

Indeed ..... ''appear'' to cover - or better still .. it will ''obscure'' that approx area.

Main deal is - the bigger the spot and more you obscure - at longer ranges in particular - the harder it can be to fully center that dot on the true target zone. For hunting tho - and again IMO - the 4 MOA is as big as I'd want go and yet it will achieve good results.

A well placed ''4 inch'' dot at 100 .. say a groundhog or coyote .. and you'll be well in kill zone providing it has been zeroed properly first. I love em! :)

Basically, the smaller the dot the more precise your aiming point. The larger the dot, the faster you can pick it up with your eye.

I have a couple of dot sights with ~1 MOA dots (a Russian PK-01V and a BSA) and while they're pretty quick, unless I turn the brightness all the way up the dot washes out in bright light.

[P95Carry]

Didn't know there was a 1 MOA dave .. but I can imagine wash out probs.

The whole deal with red dots is compromize ... each person needs to find a sorta ''middle ground'' I think plus ... being relative to desired application.

[CRUSHER]

Eotech makes a sight with a 1 moa dot with a 65 moa ring around it that I think is a good compromise.

[Don Gwinn]

Should that be 6 point 5? :eek:

[Dave Markowitz]

Don, no, that wasn't a typo about the EOTech. It's a 1 MOA surrounded by a 65 MOA circle. Nice setup, actually.

I think the 65 moa O witn a 1 moa dot is favored by shottgunners after turkey. At about 40 yds you get 28 inch circle right around his head if you patterned it right. Lots of pellets in neck and head not many in the meat. I think Bushnell Holo-sight makes something similar except it has 4 different patterns to choose from. I always wondered if one of those would work for wing shooting.
