SnidelyWhiplash Posted April 20, 2020 Share Posted April 20, 2020 Looking at several red dot options and not sure which size red dot is most appropriate. I’m guessing my primary range for the M4 would be 50 yards or less. Is there a general rule or suggestions for appropriate size? Quote Link to comment Share on other sites More sharing options...
RickRope Posted April 20, 2020 Share Posted April 20, 2020 I like 1moa, but I ended up with a 2moa Holosun with the 35moa ring. I doubt I’ll change it, i really pick up that ring quickly. Quote Link to comment Share on other sites More sharing options...
CobraBG Posted April 21, 2020 Share Posted April 21, 2020 I have the Trijicon RMR with a 3.25 and it seems perfect. Quote Link to comment Share on other sites More sharing options...

StrangerDanger Posted April 21, 2020 Share Posted April 21, 2020 I have both the 1moa and 3.5moa RMRs. I honestly can’t tell the difference in their size. When buying now, I opt for the smaller moa dot size. I never have issues locating the dot in the optic, so I figure a smaller aiming point offers more precision if needed. 1 Quote Link to comment Share on other sites More sharing options...
jimbo45 Posted April 21, 2020 Share Posted April 21, 2020 For a long gun I'd say the 1 moa dot, I have a bunch of 2 moa dot mro's and I'd be fine if the dot was smaller. Quote Link to comment Share on other sites More sharing options...
SnidelyWhiplash Posted April 21, 2020 Author Share Posted April 21, 2020 Wow! I’m really surprised that there are so many proponents of the smaller sized red dots. I was ready to order the 6 mos size after reading on another forum “Jerry Miculek uses a vortex venom but with a custom 8moa dot on his pistol and his old 6moa rmr on his shotgun.” Now I’m not so sure which to get.

DFWSFO Posted April 21, 2020 Share Posted April 21, 2020 I dont use it on my M4, but I have an RMR on my Glock 19 and would not go larger than 3.25 MOA. Unless you have vision problems, I think the 6 MOA is too big. Quote Link to comment Share on other sites More sharing options...
Milspec Posted April 21, 2020 Share Posted April 21, 2020 I looked at what Scalarworks bundles with their sync mounts and went with that. I figured since they make the sync they should have a pretty good handle on it. Quote Link to comment Share on other sites More sharing options...

Great design! 1 1 Quote Link to comment Share on other sites More sharing options...

Figure at 50 yards the dot is still just 1.25 MOA. Edited April 21, 2020 by Milspec Quote Link to comment Share on other sites More sharing options...
les_garten Posted November 17, 2020 Share Posted November 17, 2020 I am thinking about getting an SRO for the Sync rail. I have astigmatism and was thinking about getting the smallest dot possible, since they look big to me anyhow ? Any of you guys with Red Dots and astigmatism? How did you cope?

StrangerDanger Posted November 17, 2020 Share Posted November 17, 2020 Smaller the dot, smaller the smudge from the astigmatism. Running the dot at lower power helps too. I was sighting in an AR15 build yesterday with a Holosun knock off of an Aimpoint T1, and noted the smear. So I turned it down to the point where I could just barely see the dot. The lower powered dot will obstruct your target less so you can make precise aiming. I wouldn’t leave the optic in this low powered state once deployed for self defense or duty use. Just to sight in the firearm in so that you know of any aiming errors occur, they’re on you and not the sights. Quote Link to comment Share on other sites More sharing options...

benelliwerkes Posted November 17, 2020 Share Posted November 17, 2020 Typically the MOA "dot size" is similar in presentation size thru the optic lens to the operator in most optics. What is different between devices is what that dot size represents at various distances. For a shotgun a 2.5 MOA represents 0.625" @ 25 yards impact variation; an 8 MOA dot represents 2" impact variation. A 12 gauge slug is ~0..72" so a 2.5 MOA most closely represents the slug size impact at 25 yards. Double those MOA numbers for 50 yards, 1.25" v. 4" impact variation; 4X those numbers @ 100 yards. Finally, most red dot optics project the "red light" from behind the lens at an angle to the center of the rear surface of the optic lens which itself is usually angled rearward; any debris that accumulates in the area of the "projector" red light source will create blurred / distorted red dot images as the light is diffracted passing thru the trash en route to the lens, particularly with a pistol mounted optic; check / clean that area with alcohol and a Q-tip before declaring astigmatism issues.

They are out of stock right now, but the price was $495. MidwayUSA has the 2.5 MOA for $550. Quote Link to comment Share on other sites More sharing options...
