C & H Research Standard Stock 5'' A Recoil Suppressor

The C & H Research Standard Stock 5'' A Recoil Suppressor is a mercury-based recoil management system designed for shooters who want to reduce felt recoil without adding weight or complexity to their rifle or shotgun. Unlike friction pads or elastomer systems that degrade over time, this recoil suppressor uses mercury—one of the densest liquid elements available—sealed permanently in a steel case. The result is consistent, reliable recoil dampening that works the same whether you're shooting in January cold or summer heat.

Recoil matters, especially during long range sessions, competitive shooting, or when you're breaking in a new magnum rifle. Too much kick throws off your follow-up shots, amplifies flinch, and leaves your shoulder sore. The C & H Research design addresses this by letting mercury absorb and dissipate recoil energy through its own mass and viscosity. Mercury's properties remain stable across temperature extremes—only a 1% variance from freezing to 90°F—so your suppressor performs the same in spring turkey season and fall elk hunts.

Installation is straightforward: the unit is drilled and tapped for 1/4"-28 thread pitch, fitting standard stock configurations. The permanently sealed steel construction means there are no moving parts to wear out, no seals to fail, and no maintenance beyond mounting it. Once it's in, it stays in, handling whatever conditions you throw at it.

This is a no-fuss option for hunters and shooters who want recoil reduction that's proven, durable, and effective—and who don't want to worry about it failing when it matters.

Frequently Asked Questions

Does this recoil suppressor work for rifles and shotguns?

Yes. The Standard Stock 5'' A is designed for both rifles and shotguns with standard 1/4"-28 TPI stock threads.

How is this installed in my stock?

The suppressor is drilled and tapped for 1/4"-28 thread pitch, allowing it to be threaded directly into compatible rifle and shotgun stocks. It can be removed and reinstalled as needed.

Will this work in cold weather?

Yes. Mercury's viscosity varies only 1% across the temperature range from 0°F to 90°F, so recoil suppression performance remains consistent in cold hunting conditions and hot range days.

What maintenance does this require?

None. The permanently sealed steel case design means there are no moving parts to wear out and no seals to maintain. Once installed, it requires no upkeep.
