Description
Geissele built the Super Precision CompM5s mount for folks who want their red dot sitting exactly where it should, every single time. It's cut from one solid piece of 7075-T6 high strength aluminum, so there's nothing flimsy or stacked together here. This version runs an absolute co-witness height, meaning your Aimpoint CompM5s dot lines up right on top of standard iron sights for a clean, lower-the-dot-onto-your-irons picture.
What Sets the Super Precision CompM5s Mount Apart
The clamping system is where this mount earns its reputation. Geissele took the classic nut and bolt method and tightened it up, pulling the mount to your rail with 1,400 pounds of clamping force. Backing that up are three shear lugs that bite into the rail and hold everything locked, which is a big part of why this mount returns to zero so well after you pull it off and put it back on. If you shoot hard, run drills, or just want confidence that your dot hasn't wandered, that matters.
Build and Finish on the CompM5s Absolute Co-Witness Mount
This one wears a Type 3 hardcoat anodized finish in black, so it shrugs off the wear and tear that comes with real use. It tips the scale right around 2.1 ounces, keeping things light on top of your rifle without giving up any of that rock-solid rigidity. The whole thing has the fit and feel you'd expect from Geissele, who've spent years earning trust with serious rifle shooters.
It was designed specifically around the Aimpoint CompM5s, though it'll also work with similarly mounted red dot optics. If you've already got a CompM5s and you want a mount that won't be the weak link in your setup, this is the one people keep coming back to.

Frequently Asked Questions
What optic does the Geissele CompM5s mount fit?
This mount was developed specifically for the Aimpoint CompM5s red dot sight. It will also work with similarly mounted optics that share the same interface. If you're running a CompM5s, this mount drops right in.
What does absolute co-witness mean on this mount?
Absolute co-witness sets the optic so your red dot lines up directly on top of standard iron sights. When you look through the sight, your dot and your front iron sit at the same point of aim. It's the choice for folks who want their dot and irons centered together rather than sitting higher in the window.
How well does the Geissele Super Precision mount hold zero?
Return to zero is one of this mount's strong points. It clamps to the rail with 1,400 pounds of clamping force and uses three shear lugs to lock in place, so you can remove it and reinstall it without losing your zero. That's a big reason Geissele's Super Precision line has the reputation it does.
What is the mount made from and how heavy is it?
It's precision machined from a single piece of 7075-T6 high strength aluminum, then given a Type 3 hardcoat anodized finish in black for durability. Despite how solid it feels, the absolute co-witness version weighs in right around 2.1 ounces. You get rigidity without adding much weight up top.
