Most Helpful Positive Review Best Budget Red Dot By Far
I've had my M-spec FMS for several months now and I ran it through a course of fire of two days and 800 rounds. It has held up amazing and has not had any zeroing issues or anything. Sightmark has beaten other optics companies to the punch on this one.
Most Helpful Negative Review very disappointed
Was hoping that this would be an alright sight that wouldn't blow my mind but would at least last me a while. Unfortunately after 500~ rounds one of the screws that anchors the elevation pivot, broke apart inside the shaft. I thought to give this brand a shot but I'll be staying away from now on.

Pros:
  • Built solid, accurate, durable
Cons:
  • Heavy

bobcat 870

by Dave, Verified Owner from WV, United States Written on October 24, 2023
Fast shipping. Good quality and holds zero very well for way less many than some other higher priced red dots. Looks awesome on rifle. Can use with multiple magnifiers. Have always had good luck with sightmark.

Does fit over a2 gas block

by B, Verified Owner from OH, United States Written on May 6, 2023
I got it for 160 only, but if yours also comes out fuzzy try zeroing it and let the red dot stay on for a bit, it at least somewhat helped fix the all the fuzz around the reticle but still looks kinda bad lol, so I recommend just waiting for a sale def not worth 220 but good for a cheap starting optic
Pros:
  • On Sale
Cons:
  • Blurry
  • Fuzzy Dot

Good budget optic

by Jake, Verified Owner from PA, United States Written on July 9, 2022
I’m pretty pleased with this optic. It’s not an overly expensive option and it gets the job done. I’ve had mine for several months now and have not had any functional issues with it. My only complaints are that it is made in China and that I started to notice some slight chipping of the glass if I really squint. Nothing terrible and certainly not affecting the function of the optic but still there and worth mentioning. If you’re trying to avoid the Eotech/Holosun etc. price tag, this is a good bang for your buck option.
Pros:
  • cost
  • holds zero so far
Cons:
  • Made in China
  • glass finish durability
Would recommend: Yes

Good Sight

by C, Verified Owner from FL, United States Written on July 5, 2022
Quality sight that gives the impression of a high end sight such as an EoTecg without the cost. Note it is still a red dot and not a holographic sight despite the appearance being similar to a holographic sight.
