The Geissele Super Precision 34mm Extended Scope Mount is a billet-aluminum ring system built for AR-15 and M4 platforms that demand repeatable, rock-solid scope retention. Unlike lever-based mounts, this design uses Geissele's nut-and-bolt clamping method—the same approach that delivers 1,400 pounds of clamping force per fastener pair, ensuring your optic stays zeroed through heavy recoil and repeated mounting cycles. If you're running a precision rifle, a duty AR, or a long-range setup where every zero counts, this 34mm extended mount bridges the gap between aggressive ergonomics and uncompromising mechanical security.
Built from a single piece of 7075-T6 aluminum and machined as one unit, the Geissele mount achieves superior rigidity and return-to-zero consistency. The entire assembly—including the scope caps—is line-bored to ensure a perfectly uniform bore. That precision fit means you can torque your scope rings to proper spec without risk of crushing the tube. Geissele's single-piece machining also allows them to engineer cap locations that work across a wide range of optics, so whether you're mounting a compact 1-6x or a full-size tactical scope, you'll find a cap position that works.
The mount spans seven Picatinny sections on your upper receiver, stabilized by four shear lugs that distribute stress evenly. Your choice of zero or 20 MOA cant orientation supports everything from flat-range precision to field hunting and competition. Finish options include black or DDC (Desert Dirt Color) type 3 hard-coat anodize—both proven for durability in hard use.

Yes, the Geissele Super Precision is designed specifically for AR-15 and M4 uppers with Picatinny rail. It mounts across seven Picatinny sections, which is standard width for most AR receivers. If you're unsure whether your upper has sufficient rail real estate, confirm you have at least seven adjacent sections available.
The cant is the vertical angle built into the mount base. A zero cant mounts level to your receiver, ideal for close-to-mid-range work and flat-range precision. A 20 MOA cant tilts the scope up slightly, which extends your elevation turret range and is popular for long-range hunting and competition where you're dialing up significant yardage.
This is a 34mm mount. It is designed specifically for 34mm scope tubes and will not fit 30mm or 1-inch tubes.
The nut-and-bolt method is mechanically more secure and delivers higher clamping force—1,400 pounds per fastener pair—than lever-based designs. This translates to superior hold through recoil, easier return to zero, and a lower risk of scope movement during your shooting session.
