interlok adjustment system for windage and elevation

low battery indicator

CR123A battery longer battery life

InterlokTM Adjustment System

The interlok adjustment system is a internal retention system that ensure windage and elevation adjustments remain zeroed during recoil. Competitor reflex sights typically require the adjustment system be unlocked using a screw or set of lock screws. These designs can be damaged or break if the customer forgets to loosen the locking screw. The interlok adjustment system removes the need of a locking screw so shooters can make adjustments on the fly.

Low battery Indication

- 2 hour low battery indication – each press of a button the reticle will blink four times.

- 10 minute low battery indication – the reticle will continuously blink until a new battery is installed.

Longer Battery Life

Powered by a single CR123A battery, the M-Spec reflex sight has the ability to run up to 2,000 hours.

5.0 out of 5 stars Solid Optic so far
Reviewed in the United States on December 11, 2023
Style: FMSPattern Name: SightColor: Dark EarthVerified Purchase
I know this isn't a "premium brand" with the support of the community but I have very few complaints, especially for the price. The glass is crystal clear, great field of view, wide range of brightness levels and a crisp clean reticle. Sighting in was very straightforward and worked well, build quality seems very good, parallax is 100% perfect, and so far it's held zero for 2 weeks of ownership and a couple hundred rounds. I know that's not a 10 year track record but I'm happy with it. Especially for the Black Friday deal price I got. If you are looking for a more budget friendly option than some of the other brands out there, but with little sacrifice in return try it.
Cons. No shake to wake feature. It will auto shut off (in 10 mins or so if you activate it and 12hrs if you dont) but it won't turn itself back on when it senses movement. Battery life isn't great compared to some competitors but that's not a huge concern for me and my use case. It is missing some of the "ultra premium features" like auto brightness, solar operation, but if you want that you're gonna pay dearly for it...
I recommend this. For now. If it breaks in 6 months I'll surely come back and tell you.

5.0 out of 5 stars M-Spec FMS initial review (so far so good)
Reviewed in the United States on August 24, 2019
Style: FMSPattern Name: SightColor: BlackVerified Purchase
This review is for the M-spec FMS model.

So far this site has exceeded my expectations at this price point. After comparing quite a few different sights, I pretty much came down to selecting either this, or an EOTech sight (which is about 3x the price). I have little doubt the EOTech is better, but not 3x better (your mileage may vary by your perceived needs & budget).

First off, I discarded most tube style red-dot sights because they are not truly paralax-free, even though they are typically at 1x magnification. This means they aren't ideal for use with both eyes open. Both eyes open gives you a dramatically improved FOV, as the sight's body is "ghosted" over the target area because your other eye does not have this obstruction. Closing one eye while shooting with anything other than a magnifying scope is generally a bad habit. I also wanted to avoid the issue of shifting zero when the reticle is not centered (a common problem). Lastly, I didn't want a sight with relief restrictions. So I only considered "HUD style" sights.

It pairs perfectly with a Vortex 3x side-flip magnifier (with the vortex's small included spacer). I'd recommend the vortex much more highly than the magnifier amazon tries to pair this sight. If you want this sight + a magnifier + some 45 degree flip-up backup sights, you'll need more rail space than an upper has by itself. The sightmark has no eye relief though, so it works well on the back end of a hardguard rail. Without backup sights, this + a magnifier will all fit on an upper rail.

The Good:
- This is the updated and improved version of the M-spec FMS. There is an older version which has a rounded outer housing, while this one has a more beveled shape, and numerous upgrades.
- external housing stands off from the inner glass, providing excellent drop protection.
- so far, .556 recoil has caused zero issues
- same reticle as EOTech, small precise dot for longer range use, with high visibility outer ring for quick acquisition, and small bars at the top/bottom/sides for visual cues of your gun's vertical alignment.
- excellent weight for a fairly rugged build (9.6oz)
- the integrated sun/rain shade fits into the gap between the sight and it's protective external housing. There is enough play in the space to maintain the drop protection. It's a clever place to stow this added feature. Some have said it looks fragile, but I disagree. Although I wouldn't deliberately drop it onto the shade while extended, it's made of a slightly flexible plastic of respectable thickness. It's much like a rigid TPU, like a hardshell phone case. It can be a bit finicky adjusting, but it doesn't rattle or shift on it's own. I use it, if just to keep my thumbs off the lens.
- cr 123 battery is very common and puts a lot of power into a compact package. Lithium-only battery prevents use of lead acid or rechargeable batteries which lose charge on the shelf much more rapidly, and are much more temperature sensitive. (replace 'included' batteries on any electronics, they are typically bulk-purchased paste-date overstock)
- good assortment of brightness settings suited to any lighting (I'm unable to test NV settings)
- weather resistant (not ideal for navy seals, but will certainly stand up unplanned showers, spills, etc)
- tethered, thumbscrew battery cover
- quick press to turn on 'quickly'(ish), long press to turn off avoids accidental shut off
- saves last brightness setting
- FOV is excellent (for those who shoot like a pirate)
- FMS version is a bit cleaner & has less to snag than QD version. It's also cheaper, and 1oz lighter. Allen wrench attachment is simple & easy. Assuming you do not have a need for QD.
- padded neoprene zippered case has a bottom zipper, and it stays in place very well as a slip-on sight cover while storing/transporting.
- Texas designed & sold

The Bad:
- there is a blue-green hue in the glass. This seems to be caused by the anti-reflective coating on the front (tradeoff)
- buttons are a little hard to press (could be considered a good thing)
- the zeroing adjustments could stand to have a more positive click detent. With hearing protection, it's not easy to count exactly how many clicks you've made. In a mechanical scope this would be a huge issue, since weak detents are moving heavy glass & would result in an unstable zero under recoil, but I don't think this is an issue in this type of device. But it is annoying.
- there is in fact slight paralax distortion at the edges, but it's not nearly enough to interfere with smooth 2 eye use.
- brightness of the reticle varies as you move the edges of it closer to the sides of the FOV (its brighter at the edges), though I did not find this bothersome.
- light does bleed from the front. In some highly scientific kitchen hallway testing, it's quite difficult to see when the brightness is adjusted appropriately for the lighting, and is only visible when facing into the sight from precisely in front of it. It could be more noticeable in a light amplification type NV though. It is far less light bleed than a typical red-dot tube.
- I think slightly fewer brightness setting levels would allow for quicker adjustment.
- It's big. Lightweight, good FOV, but it's not compact. Granted, EOTech is a bit bigger.
- would love to know what the recommended torq for the allen wrench screws is, but there's no mention.
- though Texas designed/sold, it's made of chineseum. It's arguably much closer to gopro chineseum than to plastic scissors that break on the first cut ...but it is chineseum.

The Ugly:
- Nothing yet. I'll let you know if it breaks

Verdict:
A little substandard for Afghanistan, but good for short to mid range hunting & law enforcement use. So far it performs above it's pay grade.

4.0 out of 5 stars Not As Flexible As The R-Spec Strangely Enough
Reviewed in the United States on October 13, 2023
Style: FMSPattern Name: SightColor: Dark EarthVerified Purchase
I had the R-Spec and thought I'd "upgrade" to the M-Spec. But oddly enough in my opinion, the R-Spec offered more options than the M-Spec. The R-Spec had choices for the reticle style and color which the M did not. Other than that it's fine. If I were to need another reflex sight I'd definitely purchase the same brand and model but I'd opt for the R-Spec in the future. Besides that, everything was great. The eyebox is large enough to allow for both eyes open sighting which is an important feature in my book. Like the quality and feel of the materials. Best bang for the buck. Not an ACOG of course but one tenth the cost.

5.0 out of 5 stars Outstanding Optic! Great value!
Reviewed in the United States on April 23, 2019
Style: FMSPattern Name: SightColor: BlackVerified Purchase
I have been looking for an optic for my Mini
14 for a long time. I have tried several scopes and a couple of cheap red dot sights.
None of them really impressed me.
Then along comes the Sightmark SM26035
FMS reflex sight. I mounted it on the factory Ruger rail.
Not the best setup because the unit itself hangs off of the end of the rail a bit. I figured it was good enough to try it out at least. I went out to the Desert with some friends. We set up steel targets out to 150 yards. I had no trouble ringing the shillouet target at 150 offhand. I let other people try it out and they all loved it. Especially the wives of my friends. They were ringing steel better than I was doing. They couldn't miss!
Everyone was very impressed with the SM26035. Now I get what a lot of people were saying about a good quality red dot or reflex sight. The clarity and the intensity adjustments are amazing. In the bright sun I could see the reticle no problem. The unit is a little large. It is not like those compact red dots, but I don't care. The quality and clarity that this Sightmark has makes it completely worth it. I plan on getting an UltiMak rail that replaces the handguard real soon for a better mounting setup. I highly recommend the SM26035 FMS. Try one out. I bet you will like it.

Great sight. Close to zero out of the box. Survived a day at the range with a down pour. Great clarity and easy to use. This thing has already taken a lot of abuse on my 300 blackout. It’s built to last for sure

5.0 out of 5 stars Solid unit.

I own a Eotech, Aimpoint, and numerous other dot sights. I took a chance ordering this unit and it looks to have paid off. The sight is well built and the reticle is crisp and clear.

In many red dots I’ve used, my astigmatism causes the dot to look like a comma, or, in the case of the Eotech, it blurs. This hasn’t proved overly problematic as I can still aim at the top of the comma and get good hits on target.

The Sightmark doesn’t suffer from these issues and I don’t know why - the reticle is crisp and clear and my astigmatism is unnoticeable. Perhaps it’s just a fluke that the Sightmark doesn’t produce similar results to other dots, or maybe it’s a design element.

I very much like the auto on feature. The dot will go very bright indeed, no worry about loosing the dot in the snow on a sunny day even.

One thing I don’t like so much is the emitter needs to be kept clear for proper projection on the glass. That is to say; the emitter isn’t sealed in the same unit as the projection surface like it is in an Eotech or Aimpoint. Think of the Sightmark like a C-more, Vortex Venom, or Burris Fastfire setup, but larger. Only time will tell if this is an issue in snow or rain.

This unit doesn’t have different pattern reticles - so I’m not expecting any problems other users reported in POI shift.

It’s an expensive unit for a “cheap red dot” but it’s good value for that money.

I’m happy

5.0 out of 5 stars Great price for eotech style sight

Works great so far. Sights in very easy and holds zero. Glass is clear, no blue tint. Brightness levels are good and motion sense works great. Only needs to be turned on again after being still for 12 hours or so. Sight doesn't appear to be holographic only a larger red dot reticle. However I am not an expert and if I am wrong it would be a pleasant surprise. If you like eotech style sights but can't afford them or justify the cost this is a good alternative. However I can't speak to duty use or adverse conditions so if you do more than your typical larper then maybe don't expect as good of results. You get what you pay for. Satisfied with purchase and will enjoy using until I can justify an eotech

5.0 out of 5 stars Great optic for the money

This sight surprised me with its quality. I have shot hundreds of .223 with this optic mounted. It has held zero the entire time and given me zero issues. I have used very expensive optics before and this performed exactly how it should have especially for the price. The clarity and brightness are very impressive, better than some of its major competitors. The only thing I dislike is the sun shade feels a bit cheap, but thats being picky and very minor. Overall the optic works as designed and is great value for the money.
