The Meprolight M5 Red Dot Sight—a quick overview

***Update: Range report added at post 11***

I originally had an AImpoint Pro on my CTAR and although I like Aimpoints a lot I wanted to try something different—must be the cabin fever from not shooting since December.

I’d heard about the M5 but didn’t know much about them until recently—they’re designed specially for the Tavor so I knew it’d fit good from a height perspective. Wolverine had them in stock so I though I’d give it a try

I just picked it up last night so I’ve only had a quick rundown today—here are my initial thoughts.

Overview
The sight is similar is shape to Eotechs, but with a more angular profile. It’s a bit shorter front-to back that an Aimpoint PRO, and around the same weight—the specs say the M5 is 1/2 ounce lighter. There’s a QD mount, which is nice, too.

The sight takes one regular AA battery that inserts from the front:

There is a brightness adjustment dial at the rear left, with four settings including one night vision setting.

Windage and adjustment dials are on the front left and the top. The hood over the glass is plastic, I think. Military models have an aluminum hood. Although I don’t treat my rifles roughly I’d still prefer the aluminum version.

Initial Impressions
The red dot is 1.8 MOA so it looks more or less the same as the PRO’s 2 MOA dot. Side-by-side there is, for me, slightly less astigmatism flaring on the M5 than on the PRO, although the Trijicon reflex sights I’ve tried are better than both in this regard.

The PRO has a brighter highest brightness setting than the M5, although the M5’s dot was still easily picked up when looked at bright sunlit snow at its brightest level. There is a big difference between the night vision brightness and the lowest regular brightness—it probably wouldn't cause an issue in actual use but the lowest regular brightness seems to me to be wee bit too bright.

The sight has an auto shut-off feature if it’s left immobile for 10 minutes. In impromptu testing I found that very little movement was needed to cause the dot to re-appear…maybe less than a centimetre or so.

I really, really like the wide field of view. The glass has no tint at all, unlike the greenish or bluish tint of the Aimpoints or RMRs. There’s also no lens-effect like the RMRs have. Here’s the field of view comparison between the M5 and the PRO.

Here’s how it looks on the CTAR. I’ve got range time booked next week—I’ll update more then.

Nice photos. I recently talked with a young man in the IDF who was back home visiting relatives. He has the Meprolight on his issue micro Tavor. He told me all the guys there don't care for them and prefer the Eotech! Go figure. I guess the grass is greener!

Master-G, why did you choose the M5 over the M21?

I just bought the M21 with Bullseye reticle. Mounted it on the Tavor last night. Seems like an amazing device (haven't had any range time yet).

The M5 is a bit lighter than the M21, and I do like its adjustable brightness and simple dot. I like to try out new things, too, and I was interested to see how it would stack up against the Aimpoint.
 
Looks like a good piece of kit, and the price isn't out to lunch. I like the looks of the MOR too - a single unit with the features of both a reflex sight and a PEQ - for a lot less than a seperate reflex and a PEQ, less weight and rail space too.

I had a chance to take the CTAR out to the range today—we had a lot of late winter snow and the range has just recently re-opened. It was mostly overcast and about 8° C…not the best weather but considering the Spring we’ve had I’ll take it!

I tried at ten rounds at standing at 25m first to make sure I was on paper.

I then moved back to the 100m mark to do a final sight-in

Just for fun I tried some impromptu accuracy bench testing—no sandbags or anything, just resting the rifle on the bench. The best group was four rounds into 2” and a fifth opening it up to about 3.5”. I was pleased, but of course the CTAR is not a benchrest rifle!

Here’s what the dot looks like at 100m (it’s in between the two targets between the “7” and “8” target markers. It was hard to hold everything steady for this shot!

Lastly we tried a two relays of 10 rounds, with five simulating standing snap shooting and five rapid barricade standing.

Here are the results...not earth-shattering but I'm OK with it, especially since it was might first time out with the rifle and sight, and my first time shooting at all in 2015. Be kind! :)

I like the sight a lot—the wide field of view made it very quick to pick up the dot, and the perfectly clear, distortion-free window meant had a surprising effect I hadn’t considered. When you look at a target, then bring the sight up, there’s no change at all in what the target looks like—no colour change, no distortion to work through. What I found was that I could focus on the target “easier”, if you will…it’s like my brain didn’t have to re-correct what my eyes were seeing pre- and post-sighting. It was an unexpected benefit.

I was using the sight on its brightest setting—it was fine, but I always like to have a setting that’s one brighter or one dimmer than what you’re using, just so you know your setting is optimal.

Overall—I really like it!
