Description
There's a real advantage to keeping a few extra rounds on the gun itself instead of digging through a pack or pocket when a follow-up shot matters. The GrovTec Buttstock Cartridge Holder does exactly that, slipping right over the back of your rifle stock and putting nine spare cartridges within easy reach. It's a simple piece of gear that earns its keep every time you're out chasing game or running rounds at the range.
How the GrovTec Buttstock Cartridge Holder Works
The design is about as straightforward as it gets. Nine sewn-on elastic loops hold your ammo snug and pointed the same direction, and the whole sleeve stretches over the buttstock without any tools, straps, or hardware. The elastic loops expand to accept a wide range of calibers, so it handles everything from .223 up through .450 Bushmaster. Larger rounds will fill the loops faster, so heavy magnums may seat a bit fewer, but standard hunting rounds sit right where you want them.
Built to Last in the Field
GrovTec designs and builds these at their facility in Clackamas, Oregon, and that attention shows in the bar tack reinforced stitching that holds the loops in place shot after shot. The nylon construction and black finish keep it low-key on any rifle, and folks who've run these report the loops hold rounds firmly through recoil without letting ammo shift or drop. It's covered by GrovTec's lifetime warranty against manufacturer defects, which tells you they expect it to stick around.
A Smart Fit for Hunters and Range Days
Because it's a universal slip-on style, it works across bolt guns, lever actions, and most standard rifle stocks. Hunters like having a quick reload staged for that second or third opportunity, and target folks appreciate having a handful of rounds staged without reaching into a bag. If you want a clean look with your scope mounted, some users even run it reversed on the stock. For the money, it's one of the easier upgrades you can make to how you carry ammo.

Frequently Asked Questions
What calibers does the GrovTec Buttstock Cartridge Holder fit?
The elastic loops are designed to stretch and accept a wide range of rifle cartridges, from .223 up to .450 Bushmaster. The max elastic stretch runs around half an inch, so standard hunting rounds seat easily. Larger magnum rounds fill the loops faster, so you may fit slightly fewer than the full nine.
How does the cartridge holder attach to my rifle?
It's an open-style slip-on sleeve, so you just stretch it over the back of the buttstock. No tools, screws, or straps are needed, and you can have it mounted in seconds. The universal fit works with most standard rifle stocks including bolt actions and lever guns.
Will the ammo stay put during recoil?
Yes, the sewn-on elastic loops grip each round firmly and keep them from shifting or falling out while shooting. The sleeve itself can move slightly on the stock after repeated shots, which is normal for a slip-on design, but the rounds stay secure in their loops.
Can I run it without blocking my scope?
It sits low on the buttstock and generally won't interfere with your grip or sight picture. Some users mount it reversed on the stock to keep a clear line with a mounted scope. Positioning is flexible since it simply slides along the stock.
