Description

The EGW AR Extendariser is a one-piece riser rail that mounts over your flattop upper and lifts your optic roughly .600 inches higher, giving you a more natural, heads-up shooting position and faster target acquisition. It's machined from 6061 billet aluminum right in EGW's shop, so it carries real heft and holds its zero when things get rowdy. The top surface runs a full Picatinny spread at 9 inches long, so you've got plenty of room to slide rings fore and aft and dial in your eye relief.

What the 20 MOA Cant Does for Your AR Extendariser

The 20 MOA built into this rail tilts your optic forward, handing you extra elevation adjustment for stretching a round out past where a flat rail usually runs dry. It's a popular setup for precision AR-15 and AR-10 builds where guys are pushing distance and want to keep their reticle centered in the scope's travel. The angle also offsets the added height so your point of impact shift stays predictable.

Mounting the EGW Extendariser the Right Way

This is a clamp-on design that grabs your existing flattop rail using three cross bolts, and the screws sit flush for a no-snag profile that won't chew up your gear or your hands. EGW calls out a torque spec of 65 in/lbs on the crossbolts, which keeps the mount locked down without overdoing it. The body is shaped to follow the contour of a complete upper, so once it's on it reads like it was always part of the gun rather than a bolt-on afterthought.

Finished in a clean black anodize and made in the USA, the AR Extendariser is a straightforward way to run a full-size scope on your AR without hunting down extra-tall rings. If you've been fighting a cramped cheek weld or want more elevation on tap, this riser solves both in one piece.

Frequently Asked Questions

How much height does the AR Extendariser add to my optic?

The Extendariser raises your optic roughly .600 inches above a standard flattop rail. That extra height gives you a more comfortable heads-up shooting position and often eliminates the need for extra-tall rings. It's enough lift to make a real difference in your cheek weld without overdoing it.

What does the 20 MOA cant actually do?

The 20 MOA tilts your optic forward, giving you additional elevation adjustment for shooting at longer distances. It helps keep your reticle centered in the scope's travel so you don't run out of adjustment when reaching out. The angle also helps offset the added height for a more predictable point of impact.

How does the AR Extendariser attach to my rifle?

It's a clamp-on mount that secures over your existing flattop Picatinny rail using three cross bolts. The screws sit flush for a snag-free profile. EGW recommends torquing the crossbolts to 65 in/lbs for a solid, repeatable hold.

Will this fit both AR-15 and AR-10 platforms?

Yes, it's built to work with standard flattop Picatinny uppers on both AR-15 and AR-10 rifles. Because it rides on a MIL-STD-1913 rail, it also lets you swap scopes over from other Picatinny setups without changing rings. Just confirm your upper has a standard flattop rail before ordering.
