Most Helpful Positive Review Tread Sights for Tread pistol
Sights came with rail section and mounted on Sig Tread pistol. Sighted in and shot great groups at 50 yards. Was able to hit cans at 100 yards no problem. Not sure why there's so many negative reviews.
Most Helpful Negative Review Worthless Junk
Sig Sauer should be embarrassed that these iron sights carry their brand name. They are worthless and cannot adjust enough to obtain an actual zero. I installed these on a brand new Sig M400 Tread, as they are specifically made for, but they are junk. The front sight was already at max elevation ...

Good quality and perfect fit on M400

by Thegeach, Verified Owner from AZ, United States Written on January 11, 2025
Bought these for M400 Tread as back up sights with Trijicon MRO. Included screws for picatinny rail were short enough to fit above the gas block without issue. These irons are manual up and down (no springs) but lock tightly in the up position. Worth the money when on sale.
Pros:
  • Quality
Cons:
  • price
Best Used for:
  • Back up on AR platform

Solid Irons

by sparadise7, Verified Owner from MO, United States Written on November 24, 2024
When an EMP attack, a bullet, or failure to change the battery compromises your optic, you’re going to want to go to old school optics. These are very well designed and very rugged. These are pleasant to use and to look at but they will cost you in weight. You could consider an optic with etched glass but I prefer the co-witnessed iron look.

sigsauer quality

by Ken, Verified Owner from FL, United States Written on July 21, 2024
Awesome pop-up sites. They are not spring loaded, but that’s cool with me. I have actually bought two sets of these very well built very well constructed at a great price. You will not be disappointed.

Great Sights

by Art Lopez, Verified Owner from CA, United States Written on June 9, 2024
These sights work great. Mounted them on my Sig M400. Very easy installation and was able to get them zero really quick. Only reason I didn’t give that 5th star was because I thought they were automatic flip up sights. But you do have to manually pop them up when you press the side release. Very minor preference. Grew to not care as much and became 2nd nature to flip them up. Overall definitely solid iron sights. Would recommend to anyone looking for dependable irons.

Same price as the sights alone with a piece of mlok. Better deal

by RaceRed, Verified Owner from FL, United States Written on July 19, 2022
These are the same price as the sights alone and the mlok is added as well. These are pretty solid sights and a good value. Bought a set for my MCX Virtus and Rattler as well. I definitely recommend this set.

Solid True OEM

by Dug, from CA, United States Written on October 5, 2021
Solid and true OEM part. A little stiff had to work the button several time and WD40. Now all operates smoothly. Good price for genuine Sig. Was easy to dial in so shot is on target. Optics Planet shipping/tracking could use improvement. Made it to SoCal in 7 days
