How to Install a Sling Swivel on a Browning BPS Shotgun
A sling can make a Browning BPS easier to carry in the field, but its attachment points must be secure and correctly aligned. The BPS is available in several gauges, barrel lengths, finishes, and configurations, so the exact swivel arrangement may vary between older and newer examples.
Many BPS shotguns already have a front sling swivel mounted to the magazine cap and a rear stud installed in the buttstock. If your shotgun lacks one of these points, the safest approach depends on whether the stock is wood or synthetic and whether the receiver or magazine assembly has been modified.
Before beginning, confirm that the shotgun is unloaded. Open the action, inspect the chamber and magazine area, and keep ammunition in another room while working. Consult the owner’s manual for your specific BPS model, since factory parts and dimensions can differ.
Identify The Factory Sling Mounts
Start by examining the magazine cap and the underside of the buttstock. A factory front sling attachment usually appears as a swivel stud or eyelet incorporated into the cap. At the rear, look for a threaded stud in the lower portion of the stock, usually positioned far enough from the recoil pad to prevent splitting or interference.
If both attachment points are present, you may only need to install the detachable sling swivels themselves. If a stud is missing, compare the shotgun with the parts diagram in the manual before purchasing hardware. A replacement cap, stock stud, or complete swivel set made for the BPS is preferable to a generic part that may have the wrong thread size.
Used shotguns deserve extra inspection around these areas. Check for cracks, crushed wood fibers, stripped threads, loose escutcheons, or evidence that a previous owner drilled an oversized hole. When evaluating a used Browning alongside other field guns, the same careful inspection is useful for models such as the Browning Citori Hunter, even though its sling hardware and action design differ from the BPS.
Gather The Correct Tools And Hardware
For a simple swivel installation, prepare the sling, two compatible detachable swivels, a correctly sized screwdriver, a small wrench if required, masking tape, and a clean work surface. A padded gun vise or non-slip mat can keep the shotgun stable without pressing against the controls or finish.
If the rear stud is absent from a wood stock, you may also need a drill, a properly sized pilot bit, a depth stop, and a stock-maker’s or manufacturer-approved sling stud. Do not guess at the hole diameter or depth. The stud must engage enough material to resist sling tension without penetrating into the buttstock cavity or damaging the stock.
Avoid using excessive thread-locking compound. Some products can migrate into the wood, stain the finish, or make later service difficult. Degrease only the metal threads when appropriate, and follow the hardware maker’s instructions.
Install A Front Swivel Stud
If your BPS uses a magazine-cap swivel, first ensure the action is open and the shotgun is completely unloaded. Support the barrel and unscrew the magazine cap by hand. Do not clamp the barrel or use pliers on the cap, since cosmetic damage can result.
Inspect the cap’s threads and the spring or retention components beneath it. Replace damaged hardware rather than forcing it back into service. Install the compatible cap or swivel component, then tighten it firmly by hand. The swivel eye should sit in a position that allows the sling to move freely without rubbing against the barrel, magazine tube, or fore-end.
Cycle the action several times after reinstalling the cap. Watch for contact between the front swivel and the moving fore-end. If the attachment point interferes with operation, stop and correct the issue before attaching the sling.
Fit The Rear Stud To The Stock
When a rear stud is already installed, check that it is tight and perpendicular to the stock. Hold the stud while tightening its retaining nut, if the design uses one, so the hardware does not twist inside the stock. Protect the finish with masking tape or a soft cloth while using tools.
Installing a new stud in a wood stock is more demanding. Mark the location on the centerline of the buttstock, away from the recoil pad screws and any internal hollow section. Measure the available depth and use a pilot bit with a physical stop. Apply steady pressure and drill only as deep as necessary for the mounting hardware.
Synthetic BPS stocks can have hollow interiors or molded reinforcement ribs. Drilling without knowing the stock’s internal structure may produce a weak attachment or damage the stock. If the correct position is uncertain, have a qualified gunsmith install the stud. Professional help is especially appropriate for a valuable older shotgun or a stock with visible cracks.
| Attachment point | What to inspect | Common concern |
|---|---|---|
| Magazine cap | Threads, alignment, swivel clearance | Contact with the fore-end |
| Wood stock stud | Depth, centerline, surrounding wood | Splitting or stripped threads |
| Synthetic stock stud | Internal reinforcement and backing | Weak pull-out resistance |
| Detachable swivel | Locking gate and rotation | Accidental release |
Attach And Adjust The Sling
Once both studs are secure, press the release buttons or gates on the detachable swivels and attach them to the front and rear mounting points. Confirm that each swivel is fully seated. Pull gently on the sling at each connection and observe whether the release mechanism remains closed.
Install the sling with the adjustment buckle positioned where it will not press against your neck or interfere with the action. A two-point sling is generally the simplest arrangement for a pump shotgun. Keep the sling short enough to control the firearm, but long enough to avoid pulling the stock sideways when the shotgun is shouldered.
After fitting the sling, inspect the receiver, safety, trigger guard, and fore-end for interference. The sling should not obstruct the safety button or become trapped during normal operation. If you use a padded or wide hunting sling, check its clearance with a coat and with the shotgun mounted to the shoulder.
Check Security Before Field Use
Perform a careful unloaded function check. Open and close the action, operate the safety, and move the shotgun through several carry positions. Watch the sling attachment points for rotation, loosening, or unusual stress. The front swivel should remain clear of the magazine cap and fore-end throughout the movement.
A small amount of routine firearm maintenance helps prevent grit from affecting nearby hardware. Use the BPS owner’s manual for lubrication points, and keep oil away from sling webbing because it can weaken or stain some materials. For a broader example of careful firearm care, review this guide to properly lubricate a Browning 1911 pistol, while remembering that shotgun lubrication points are different.
Practical Checks Before Carrying
Use these checks before taking the shotgun into the field:
- Verify that the chamber and magazine are empty before installation or inspection.
- Confirm that the front and rear hardware match the exact BPS configuration.
- Test each swivel’s locking mechanism and inspect for cracks or deformation.
- Check that the sling does not interfere with the safety, trigger, action, or fore-end.
- Recheck the studs after the first outing and periodically thereafter.
A sling swivel is a small component, but it carries the weight of the shotgun while walking, climbing, or crossing uneven ground. If a stud spins, pulls out, or shows stock damage, remove the sling and stop using that attachment point until it has been repaired.
For replacement parts or a different BPS configuration, compare the firearm’s gauge, stock material, finish, and model details with the listing information before ordering. When installation requires drilling, structural repair, or uncertain factory-part identification, arrange service through a qualified gunsmith. A secure sling setup lets you carry the shotgun confidently while preserving safe handling and reliable operation.
