Most Helpful Positive Review Great for LPVO
Strike Industries gets a lot of hate but this is one product they offer that I can vouch for. First of all they are quality and solid as can be. They are also extremely low profile and fit under my LPVO. But the winner for me was when these sights are flipped down, they have extremely low profile pistol style sights, which when using an LPVO, lines up with the crosshairs in the scope which can help with accuracy

Strike Industries Polymer Backup Sights

by Vincent Vincent Mosley, from GA, United States Written on July 11, 2025
I was looking for a set of back up sights that has a flush looking fit and durable. I can say this set is exactly that. Doesn’t look bulky on my 300 B/O like most I’ve seen and the materials are tough.

SIBUS Polymer

by MrDrProfRay, Verified Owner from NV, United States Written on June 13, 2025
For the price as a whole set, it’s really not that bad. I got a pretty sturdy set, to test if it’ll get knocked back I put it on my 338LM PR and it handled the recoil. So I put it on my new ARP in 5.56 and it handles great. My only question is if it’ll handle the continuous recoil once I put tickle mode on it lol

flat and light weight.

by ArcherBow, from KY, United States Written on May 30, 2025
These are very similar to Magpul Industries MBUS Pro but made of polymer. Will co-witness with red dots. Also these being sold as a set with reasonable price.

Strike Industries Polymer Backup Sights

by Lanny Stricklett, Verified Owner from OH, United States Written on April 20, 2025
I bought these more out of curiosity than anything. I mean, back up sights for your back up sights?
So I envisioned these on a rifle with a magnified optic (scope) mounted with see through rings, to have an emergency sighting system while the scope is still mounted if the scope does a crash and burn. Once the scope is removed at first opportunity you could use the conventional flip up sights. The concept is solid, the execution, not so much.
First off, "notch" of the rear "pistol" sight back up sight is waaaaay to wide to use with the sights mounted at normal carbine length. They would need to be mounted somewhere in the range of normal pistol sights to be useable. But in doing so, you lose the precision possible with carbine or rifle length sight radius when using the sights as flip-up sights. Maybe they might be useable on a very short barreled AR pistol but for any normal carbine or rifle type applications the back up "pistol" sights are absolutely useless. Also, the back of the sights, the side toward the shooter, is sloped. They're also serrated to prevent glare, but when I see the back of a rear sight sloped, along with that obscenely wide notch it makes me think the person who designed it had no clue what they're doing.
They also seem to be of rather fragile construction. I doubt they would survive a hard knock if they were flipped up. I would describe them as "airsoft quality". I would not trust them on anything for serious social diplomacy.
The upside is the s...

Nice, Affordable, Strong

by Johnson, Verified Owner from CO, United States Written on January 14, 2025
These seem to be as good as any others. They are not spring loaded like the MBUS, but that’s not a deal breaker for me. They are strong, tool less zero, and very low profile. I’d buy them again.
Pros:
  • Low profile
  • Strong material
Cons:
  • not spring assisted
Best Used for:
  • backup iron sights
Would recommend: Yes

Great Civilian use flip up sight

by C Bartlett, Verified Owner from MO, United States Written on January 12, 2025
Informational:
Manual flip up. Not spring loaded.

Pros:
Small footprint and lightweight.
Not difficult to deploy
Good sight picture
Easily adjustable
Mounting feels secure despite small parts

Cons:
Either sight position can be easily knocked back down. This makes it less ideal for duty type situations.

The small lightweight design makes it ideal as a backup sight for home defense or for a secondary weapon like a truck gun.
Pros:
  • easy to adjust
  • Sight picture
  • Small footprint
  • easy to deploy
Cons:
  • it may be susceptible to being knocked back down in demanding situations
Best Used for:
  • truck gun
  • civilian use
Would recommend: Yes

Very Impressive

by Three Gun Hero, from AR, United States Written on December 23, 2024
I’ve exclusively used MBUS sights over the last 15 years and decided to give these a try. The quality is really nice and the price point can’t be beat. These will likely become my new backup sights of choice. They nailed it with these. I absolutely recommend.
Pros:
  • Quality & Price
Cons:
  • None
Best Used for:
  • Backup sights
Would recommend: Yes

Nice Practical Sights

by Alexander Milner, Verified Owner from OR, United States Written on September 29, 2024
Popped these babies on and hit a hopping target (soda can) 5 times in a row at 40-ish meters. Required minimal windage to be spot on. I like their look. Good for the price. Added to my growing collection of Strike Industries accessories
Pros:
  • Looks good
  • does sight stuff
Cons:
  • none yet
Would recommend: Yes

Great quality and fit

by JB, Verified Owner from NC, United States Written on July 21, 2024
The height is great! Like it better than my Magpul BUIS. Although the pistol style sights when it is flipped down are basically useless on an AR. Might be useful on a PCC with no buffer tube.
