This AmeriGlo set is made for one job and does it well: giving you a clean, elevated iron sight picture that lines up right through the window of an Aimpoint COA red dot. If you run a factory A-Cut Glock 43X or 48, these sights sit at the correct height to co-witness with the optic and stand in as dependable backups if the dot ever goes dark. The front carries a green tritium lamp so you keep a reference point in low light, and both front and rear wear blacked-out outlines to cut distraction and let your eye settle fast.
The A-Cut and COA system is a bit different from a traditional optic plate. The Aimpoint COA drops deep into a milled slide cut and is actually held down in part by the rear sight, so the irons are part of what keeps the optic locked in place. That means fitment matters, and these are cut specifically for the 43X and 48 Slimline A-Cut/COA setup, not a general dovetail sight.
Geometry here is dialed for the slimline platform. The front blade runs .125 inch wide by .240 inch tall, paired with a square rear notch measured at .150 inch, giving you a balanced front-to-rear relationship that reads quick without feeling cramped. The green tritium front and matte black outlines keep everything glare-free in daylight and glowing when the sun drops.
AmeriGlo builds these to a 16-inch-pound torque spec and pre-applies threadlock on the screw, so you get consistent, repeatable tension when you seat the rear that helps hold the COA in position. Snug down to spec and you are set. Between the tritium reference, the slimline profile, and the tight tolerances built around the COA footprint, this set is a smart match for anyone running the factory Aimpoint COA combo and wanting real backup irons behind the dot.
This set is cut specifically for the Glock 43X and 48 Slimline slides that use the A-Cut/COA interface. It is designed to co-witness with the Aimpoint COA red dot, so it is not meant for standard-dovetail slides or MOS-cut models. Confirm your slide is the factory A-Cut/COA version before ordering.
Yes. The set gives you an elevated co-witness sight picture through the Aimpoint COA window and serves as reliable iron sights if the optic ever goes dark or loses power. The green tritium front dot means you keep a usable reference in low light even without the dot running.
On the A-Cut/COA system, the optic seats deep into a milled slide cut and is partially secured by the rear sight rather than by screws passing through the optic housing. That makes the rear iron part of the mounting system, which is why this set is matched to the COA footprint. AmeriGlo calls for 16 inch-pounds of torque and pre-applies threadlock to help everything stay locked in place.
The front carries a green tritium lamp with a black outline, and the rear is a blacked-out square notch. That combination gives you a clean, single-focus front dot without competing rear dots to distract your eye. In daylight the blacked-out outlines stay glare-free, and the tritium glows once the light drops.
