Description
The Fortis Shift Vertical Grip is one of those pieces of kit that quietly changes how your rifle feels in the hands. It runs as a dedicated vertical grip when you want to wrap up and drive the gun, or as a comfortable hand stop when you switch to the thumb-over-bore hold. That flexibility comes from the organic, angled shape, which lets you index off your forefinger, ring finger, or pinky depending on how you like to shoot. Mount it to any Picatinny rail and you've got a grip that adapts to your style instead of forcing you into someone else's.
What Sets the Shift Apart
Most vertical grips ask you to commit to one way of holding the rifle. The Shift doesn't. The finger notch and skeletonized cut give you real ergonomic room, which is a big deal if you've got larger hands or you jump between shooting positions. Folks who've run it tend to point out the fit and finish right away, with clean machining and no tool marks, plus how light it feels once it's on the gun.
Built From One Piece of Billet
The Shift is machined from a single block of aircraft-grade 6061-T6 aluminum and wears a Mil-Spec Type III hard coat anodized finish, so it shrugs off knocks, weather, and hard range days. At roughly 3.4 ounces it barely registers on the balance of your build, yet it feels plenty stout under load. The skeletonized profile isn't just for looks either, it's what keeps the weight down without giving up strength.
Installation is about as simple as it gets. The grip attaches to standard 1913 Picatinny rails using slotted screw hardware, so a common screwdriver and a couple of minutes is all you need to get it clamped down and out on the range. It's made in the USA, and it pairs well with AR-15 and other tactical platforms where you want confident control up front.

Frequently Asked Questions
Can the Fortis Shift be used as a hand stop instead of a full vertical grip?
Yes, that's the whole idea behind the hybrid design. You can wrap it as a dedicated vertical grip or run it as a comfortable hand stop when you go thumb-over-bore. The angled shape and finger notch let you index off different fingers depending on which hold you prefer.
What rails does this version of the Shift mount to?
This Standard model is built for 1913 Picatinny rails and attaches with slotted screw hardware. If your handguard is M-LOK or KeyMod instead, Fortis makes separate versions of the Shift for those interfaces. Double-check your rail type before ordering so you get the right fit.
How heavy is the Fortis Shift Vertical Grip?
It comes in right around 3.4 ounces, which is genuinely light for an aluminum grip. The skeletonized, one-piece billet design keeps weight down without sacrificing strength, so it won't throw off the balance of your build.
Is the Shift durable enough for hard use?
It's machined from a single block of aircraft-grade 6061-T6 aluminum and finished in Mil-Spec Type III hard coat anodizing. That combination holds up to weather, abrasion, and repeated range sessions. Owners regularly call out the clean machining and solid fit and finish.
