MX Tactical Front Sight – ST 12 Gauge

MX Tactical Front Sight – ST 12 Gauge

SKU: mx-tactical front sight – st 12 gauge

This fiber optic front sight lines up seamlessly with the MX Tactical Rear Sight. This is designed for plain-barrel Mossberg shotguns with or without an extended magazine tube. Steel side guards protect the fiber optics from serious punishment. NOT FOR GUNS WITH BREACH MUZZLES (You will need our heavy barrel model with a shim - MX Tactical Front Sight - HB).

  • Sight base is CNC machined from 6061-T6 aluminum with matte black hardcoat anodized finish
  • Clamping band is carbon steel, with black oxide finish
  • Comes with shims to fit a range of barrel diameters
  • Use with MX Tactical Rear Sight for complete system

NOTE: If you have a Mossberg Shockwave 590, order the Heavy Barrel version of the MX Front Sight

I have a heavy barrel on my shotgun. Will this work with it?

No. You will need our MX Tactical Front Sight - HB.

I have a ribbed barrel. Does the system work with that?

No. Sorry, at this time, none of the Mossberg-related front sights work with ribbed barrels.

I have an after-market magazine tube extension. Will the system work with that?

Yes! If the front bracket is close to the end of the barrel, you may need to mount the sight behind the bracket. The clamp can be opened to allow this. See installation instructions.

My magazine tube is big – over 1” in diameter. Can I still use the system?

Yes! The diameter of the extension doesn't matter with this band clamp design.

Can I mount an accessory rail on this sight?

No. An accessory rail cannot be used on this sight. We will be coming out with a tactical version, similar to our EX Front Sight - PB, for those with plain barrels and a standard magazine. Sign up to be notified when this becomes available.
