Description
LaRue Tactical has spent years earning a reputation as the go-to name for quick-detach optic mounting, and this LT915 cantilever mount is cut from that same cloth. It's machined for a 34mm scope tube, sits at a 1.54" mount height, and runs a flat 0 MOA base, making it a natural fit for a wide range of magnified optics on flat-top AR-pattern rifles. Finished in black anodizing over precision-machined aluminum, it's built to shrug off a lifetime of use.
What the LT915 Cantilever Does on Your Rifle
The cantilever design pushes your optic forward over the handguard or barrel nut, so you're not stuck spanning from the receiver to the rail. That forward position is the whole point here. It lets you dial in proper eye relief without cramming the scope back into your face, which matters a lot when you're running a modern MSR setup and want a comfortable, repeatable cheek weld. The 0 MOA base keeps things level, which is what most folks want for general-purpose and closer-to-mid-range shooting.
Quick-Detach and Return to Zero on the LT915
This is where LaRue mounts have always shined. The QD lever lets you pull the optic off and reinstall it without losing your zero, which is a huge deal if you're swapping optics between uppers or breaking things down for storage and travel. LaRue backs that return-to-zero reputation with tight tolerances and a robust backbone connecting the rings, so your glass stays put under recoil.
Why the LT915 Earns Its Spot
Made in the USA, this mount carries the kind of build quality that has folks coming back for a second or third one. Owners of LaRue mounts consistently point to the fit, finish, and dependable zero retention as the reasons they trust the brand. If you want a mount you set once and forget about, this one belongs on the short list.

Frequently Asked Questions
What size scope does the LaRue LT915 mount fit?
This mount is built for optics with a 34mm main tube. It won't fit 30mm or 1" scopes, so make sure your glass has a true 34mm tube before ordering. If you're running a different tube size, LaRue offers this same style mount in other diameters.
Does the LT915 cantilever mount hold zero when you take it off and put it back on?
Yes, that's the whole idea behind LaRue's quick-detach design. The QD lever lets you remove and reinstall the optic without losing your zero, which is why folks trust these mounts for swapping between uppers or breaking a rifle down for travel. It's one of the most consistent return-to-zero systems out there.
What does 0 MOA mean and is it right for me?
A 0 MOA base sits your scope level with the bore instead of adding built-in elevation. That's the go-to choice for general-purpose shooting and closer-to-mid ranges where you don't need to squeeze out extra elevation for long distance. If you're chasing very long range, a canted base like 20 MOA might suit you better, but 0 MOA covers most use.
Will this LaRue mount work on my AR-15 or AR-10?
It's designed for flat-top AR-pattern rifles with a Picatinny top rail, so it drops right onto most AR-15 and AR-10 uppers. The cantilever pushes the optic forward over the handguard for proper eye relief. Just confirm you have enough rail real estate up front for the forward ring position.
