Why These Stock Inserts Are a Smart Upgrade
Secure Mounting in Synthetic Stocks
Engineered to reinforce thin, hollow, or polymer stocks so sling studs and accessory screws won’t pull out under load.
Load-Spreading Design
Internal backing creates a larger contact area, reducing stress on the stock material and helping prevent cracks around the mounting point.
Cleaner, More Professional Install
Keeps studs square and tight to the stock, improving both appearance and function.
Versatile, Universal Use
Works with most front and rear sling locations on common hunting rifles and many shotguns; useful for bipod studs or accessory attachments that use a similar stud/screw format.
Corrosion-Resistant Construction
Durable finishes help resist rust in wet, muddy, or salty environments.

Installation Overview (High-Level)
Unload & Verify Clear. Safety first—remove the bolt/mag and verify an empty chamber.
Plan the Location. Mark the fore-end centerline and/or buttstock toe-line; confirm barrel and magazine clearances.
Drill Pilot Hole(s). Use the recommended bit size for your insert; keep holes square to the stock surface.
Fit the Insert. Place the insert inside the stock cavity (or per instructions) so it backs up the stud/fastener.
Install the Stud/Hardware. Tighten until snug; avoid over-torque. Verify the insert holds firm and the stud is square.
Function Check. Attach swivels and your sling; confirm free rotation, no binding, and no flex at the mounting point.
Unsure about drilling a thin or closed cavity? A qualified gunsmith can perform the install and ensure proper alignment and torque.
Compatibility Notes
Rifles: Works on most bolt-action and many semi-auto sporting rifles with sling-ready stock positions.
Shotguns: Compatible with many pump and semi-auto field guns; some models may need mag-cap or barrel-band mounts up front (sold separately).
Swivels & Slings: Pairs with standard 1" or 1.25" detachable swivels (check stud and sling width).
Materials: Optimized for synthetic/composite/hollow stocks; can also reinforce thin wood areas where splitting is a risk.
Care & Maintenance
Check Tightness: Re-check stud/fastener tightness after long hikes, big temperature swings, or airline travel.
Protect Surfaces: Wipe with a lightly oiled cloth after wet hunts to prevent corrosion.
Annual Inspection: Verify inserts haven’t shifted and studs remain square; re-snug if needed.
Frequently Asked Questions
Q: Do I still need a swivel stud?
A: Yes. The insert is the internal backing; you’ll use your preferred sling swivel stud or accessory stud with it.
Q: Will this fit my synthetic shotgun fore-end?
A: In most cases, yes. Measure the cavity and confirm you have access to position the insert. Some fore-ends may require a through-bolt or a model-specific mount.
Q: Does this work with wood stocks?
A: It can reinforce thin or soft areas in wood stocks, but traditional wood-screw studs often work fine in solid wood. Inserts are most beneficial for hollow/synthetic stocks.
Q: What tools do I need?
A: Typically, a drill, correct bits, and a driver. A center punch and masking tape help with straight, chip-free holes.
Q: Will the insert rattle inside the stock?
A: When installed correctly and snugged with the stud, the insert should be secure and rattle-free.
