Dial-in rock-solid rear support and cleaner recoil tracking with the MDT Rear Bag Rider (5"). Purpose-built for modern chassis and stocks with M-LOK® underside slots, this CNC-machined aluminum rider provides a long, straight, low-friction surface that glides predictably on your rear bag. The result? Finer vertical corrections, faster target reacquisition, and more consistent natural point of aim—whether you’re cleaning stages in PRS/NRL matches, truing dope on steel, or settling into a prone hide for varmint duty.

Why the MDT 5" Bag Rider Improves Your Hits

• Stable, repeatable interface: The 5-inch length spreads load over the bag for smoother micro-elevations and less wobble shot to shot.

• Precision machining: 6061-T6 aluminum (CNC) with hard-anodized finish keeps weight down while resisting dings, solvents, and weather.

• True straight track: Flat, linear profile promotes recoil straight back—reducing muzzle hop and helping you spot impacts through the scope.

• Fast M-LOK® install: Mounts directly to M-LOK® slots on MDT and other compatible chassis/forends—no extra adapters needed.

• Bag-friendly edges: Lightly radiused edges encourage smooth bag movement and prevent catching or tearing.

• Competition & field ready: Optimized for PRS/NRL, rimfire precision, and hunting prone where fine elevation control is critical.

Installation (Quick Guide)

1. Unload & clear the rifle.

2. Align the bag rider with your stock/chassis M-LOK® underside slots.

3. Insert M-LOK® nuts/screws, lightly snug.

5. Confirm no interference with your bipod, sling studs, or support gear.

Pro Tips for Best Results

• Pair with a medium-firm rear bag (e.g., sand-filled) for crisp elevation control.
