All the Steiner Optics scope mounts we carry that are machined from aluminum are here. All products are sourced direct - genuine stock, no substitutes.
Steiner Optics mounts are engineered to stay put under recoil and install without the shimming that lower-tier hardware often needs. A mount is the interface between receiver and optic, and every impulse goes through it. Get the torque spec right on installation and it will hold zero through the life of the rifle.
Confirm whether your rifle uses Mil-Spec 1913 Picatinny, Weaver grooves, or drilled-and-tapped receiver holes before ordering. Each product page lists the specific action or rail compatibility.

Amazing optic. Holds true on my duty weapon after well over 1000 rounds.
This isn't my first holosun, been happy with the quality of them, and the green reticle is much easier to see with my astigmatism. Circle dot setup also helps my aging eyes acquire target quicker. Shipping was pretty quick as well.
I installed this on a LFA Apollo 11. I’ve had good luck with the Sig Romeo line so I figured I’d give this optic a try. The dot is nice and crisp and installation is easy. Sig only provides M3 and M4 screws. If you’re pistol uses a different size, you’ll need to make sure you have the appropriate screws.
Price was on point, shipping was fast, and product was what I ordered. Absolutely nothing to complain about and will definitely order from them again!
The Holosun 407K X2 Green 6 MOA dot was exceptionally easy to install and fit my S&W M&P Shield X perfectly. The optic arrived accurately zeroed right out of the box, requiring little to no adjustment before heading to the range.
The green dot is crisp, bright, and easy to acquire. As a 75-year-old shooter, I found that it significantly improved my target acquisition speed and overall sight picture compared to iron sights alone.
I was also extremely impressed with Freedom Gorilla's shipping. My order arrived in approximately 36 hours, which was much faster than I expected.
Overall, this optic has exceeded my expectations in terms of fit, performance, and ease of use. I would not hesitate to recommend both the Holosun 407K X2 Green and Freedom Gorilla to other shooters.
Holosun 407k is a Perfect fit and choice for my S&W 9mm Equalizer.
This is a great red dot for the M&P Shield Plus. The adapter plate worked correctly, although I had read where some people mentioned that they didn't need it....mine definitely did need it. The only two things that I noticed with it, were that 1) I can accidentally turn the Holosun off when manipulating the slide, and 2) I do wish there was an auto brightness feature. My previous CT red dot automatically adjusted, and I think I liked that better. But, this Holosun is a better unit, and I really love the ring for quicker acquisition of the dot.
They are absolutely superior to the OEM screws. They look absolutely amazing to bring out the function and finish of the firearm.
