SRO What Size MOA?

[RustyNail]

I'm about to purchase the Trijion SRO but am unsure of the MOA I should get. It's between the 2.5 and the 5. I'm 66 and the eyes are having some problems. Reviews indicate that if you crank up the power the 2.5 would work. Any thoughts?

Thanks

Having used both, I prefer the 5 for USPSA. My wife and friends do as well. For EDC, the auto works better with the five. Nothing wrong with the smaller dot, especially if you want to shoot beyond 100.

I have the 5MOA on 2 different guns I use for USPSA and steel challenge. it has worked out very well for me so far (5000 rounds later)

I'm 70 and have all sorts of eye problems. But as GJM said, unless you're just going for accuracy at distance, I've found the 5 MOA to work best all around. I have other red dots, several with smaller dots, and while I like them for more static shooting, for "hurry up and go bang" situations, the larger dot works best . . . for me.

I’ve become a big fan of the larger dots on handgun. 5 MOA for me.

(no experience with the SRO)

For general purpose (self defense and a modest level of participation in action pistol competition), I prefer the larger dot for 25y and in. I find the larger dot a bit more forgiving of poor fundamentals and index. I'm a bit more confident in my ability to find and track the larger dot. At this point in my development, I find that Pro outweighs the precision capability of the small dot. I could see how that perspective might change if I had better fundamentals or more interested in longer range precision shooting.

Yeah going to pile on the 5moa bandwagon for pistol use here.

Have both the 2.5 and the 5.0. I will most likely sell the 2.5 and buy another 5.0.

[miller_man]

Another vote for 5, will be getting another one soon.

Not exactly apples to apples as I am referring to different optic brands but I've had a personal experience with 2.0, 2.5, 3.25, 5.0, 6.5, and 8.0 MOA dots. Unless I am contemplating bullseye competition, I would not willingly choose anything under 5.0. I am slowly divesting from 2.5 DPPs for games and setting my carry guns with 6.5 RMRs.
As far as cranking the 2.5 up, you get a blooming effect and you lose the dot border definitions.

Learning has occurred! :p

2 2.5 SROs and 2 5.0 SROs here. One of each required replacement by Trijicon. 5.0 is definitely better for practical shooting. SRO dot appears to my eyes smaller than other dots of nominally equal size. SRO 2.5 looks smaller than DPP 2.5. SRO 5.0 appears smaller and crisper than RMR 3.25, shield 4.0 or docter 3.5. Could just be my eyes or an illusion. SRO 5.0 is best looking and most useful rds I've used thus far.

What was the operation of the dots like before they failed. ie were there any indicators?

One of the 2.5 MOA had no auto adjust mode out of the box. Didn't actually need it because it's far less effective than the RMR's auto adjust, but figured faulty electronics should be replaced. Trijicon replaced promptly.

One of the 5 MOA before it hit 500 rounds started turning off unpredictably while shooting. Good practice going to backup irons. Trijicon replaced promptly.

Been focusing on iron sights ever since. I'm sure at some point I'll haul out the dots again to facilitate getting to the next level with irons. Dots are good for that.

Being I just ordered myself a 5 minute, good to hear that’s the preferred dot size. Being I run an 8 on my open gun with old school CMore, (dang I remember when that was the hot newness), a 5 made the most sense.

[RustyNail]

Thanks to everyone that replied. I got the Trijicon SCR in 5 MOA. Installed in on the Walthers PPQ M5 and it's just what my eyes needed. Turning the power down or up will adjust the dot size. I am glad I didn't get the 2.5.

[strow]

For those that are transitioning to the larger MOA dots can you give me detail and explanation for the preference?

Is this a pretty consistent preference across multiple brands and models or just the SRO?

[YVK]

Better visibility allowing for easier and faster dot pickup, especially in adverse lighting conditions.
Lesser propensity to washout.
No need to crank the intensity to improve visibility, thus avoiding excessive blooming.
Easier streak tracking when shooting at speed.
No practical effect on long distance accuracy.

Those are my personal observations. Some people reported less perceived wobble with larger dots, I have not noticed that.

I recently decide to give the SRO another shot after getting a defective unit early on. I was previously using 3.25 MOA RMRs, and my defective SRO was the 2.5 MOA.

I decided to go with 5 MOA this time, mostly because of this thread. I’m very glad that I did. The SROs seem to have cleaner dots than the RMRs so I don’t get as much blooming from my astigmatism, which is why I preferred the smaller dot before. The 5 MOA is still plenty precise and very easy to track.

I find smaller dots work well on long guns, larger dots are better on handguns. The 3.25 RMR on my Benelli M2 centers the dot perfectly every time because the index is the same every time. The 5 MOA SRO is my favorite pistol RDS not just because the window size/shape makes finding the dot easier, but the dot itself seems sharper and perfectly sized for rapid acquisition. I had Primary Machine mill one of my CZ Shadows for the SRO 5; what a great combo:

Thanks to this thread, ordered up a 6moa in lieu of the original idea of a 2moa. It’s going on my HK USP .45 woods gun. Common sense had me looking at the 6, but friends and “other internet sources” had me put the 2moa in the shopping cart. Thankfully this thread, and a self imposed 72hr waiting period before I hit the “buy” button saved me once again. If you don’t have a similar rule, I wholeheartedly suggest it. It’s saved my butt a few times!
