Lock in your sling exactly where you want it—without the dreaded “sling wrap.” The GrovTec US Limited Rotation Push Button Bases (GTHM279) give you rock-solid, QD push-button attachment points while mechanically limiting swivel rotation. The result is a quiet, tangle-resistant sling setup that stays oriented for fast shouldering and smooth transitions. Machined to GrovTec’s proven standards, these bases are an ideal upgrade for AR-platforms, precision rifles, shotguns, and hunting carbines that run QD swivels.
Whether you’re building a duty-ready rifle, refining a competition rig, or tuning a backcountry hunting setup, GrovTec’s LIMITED ROTATION bases keep your sling under control, snag-free, and repeatably positioned.
Why Choose GrovTec Limited Rotation Bases
QD Convenience + Rotation Control: Accept all standard push-button QD swivels while limiting swivel arcs to prevent sling twisting and cable wrap.
Stay Oriented, Move Faster: A controlled swivel arc keeps your sling lying flat, improving speed to shoulder and reducing fumbles around barricades or brush.
Silent, Secure Engagement: Positive detent capture holds QD posts tight and rattle-free—no squeaks, no play, no drama.
Rugged Build, Field-Proven: GrovTec hardware is known for duty-grade durability—designed to survive hard classes, rain, dust, and recoil.
Clean, Low-Profile Footprint: Minimal bulk that won’t snag on kit or catch on clothing; perfect for two-point slings on modern rifles and shotguns.

Real-World Benefits
No More Sling Twist: Limited rotation keeps the sling flat against the rifle and your body—less time untangling, more time shooting.
Better Retention & Control: Predictable sling position aids weapon retention, safer muzzle management, and smoother shoulder transitions.

Improved Comfort: A properly oriented sling spreads weight more evenly, reducing hot spots on long days.
Ideal Use Cases
AR-15 / AR-10 Builds: Anchor front and rear sling points without free-spinning swivels wrapping your sling around the stock or buffer tube.
Precision & PRS Rifles: Keep your sling straight during barricade and tripod work for fast, repeatable positions.
Hunting Carbines & Shotguns: Move through brush without a sling twisting and snagging on branches.
LE/Mil & Duty Setups: Reliable, quiet hardware that preserves consistent weapon handling under stress.
Installation & Fit Notes
Choose Mounting Location: Most stocks, handguards, and forends with QD sockets or flat real estate can host a base—verify clearance inside the furniture.
Attach Per Instructions: Use the included mounting hardware (if supplied) or appropriate screws/nuts/T-nuts for your stock/handguard material.
Thread Locker: Apply blue thread locker to fasteners; torque to manufacturer specs.
Function Check: Insert QD swivel, confirm limited rotation, and ensure the push-button detent locks securely.
If you’re mounting to thin composite or wood stocks, use proper backing plates or T-nuts to prevent pull-through.
Care & Maintenance
Inspect Regularly: Check tightness and verify the QD detent captures firmly after range days or field hunts.
Keep Clean & Dry: Wipe away moisture and grit; a light film of protectant can help prevent corrosion.
Check Swivels Too: Reliable bases deserve reliable swivels—inspect the push-button and bearings for smooth operation.
Frequently Asked Questions
Q: What does “limited rotation” actually do?
A: It restricts the swivel’s turning arc, preventing the sling from twisting around the stock/forend—keeping orientation consistent.
Q: Will these bases work with my existing QD swivels?
A: Yes—standard push-button QD swivels are compatible.
Q: Can I mount these on a wooden hunting stock?
A: Yes—use the correct wood screws or threaded inserts and a backing plate/T-nut where needed.
Q: Do they rattle or loosen over time?
A: When properly installed with thread locker and torqued, GrovTec bases are quiet and secure. Periodic checks are still recommended.
Q: Front or rear mounting?
A: Either. Many shooters run one at the forend and one at the buttstock to maintain a clean two-point sling line.
