Midwest Industries, Universal Shell Holder, MLOK Compatible, Fits 357 Magnum to 45-70, Matte Finish, Black - MI-USH - 812102034360
Product Description
Carrying extra rifle cartridges on lever-action or tactical rifles often relies on fabric buttstock sleeves or elastic loops that stretch, shift under recoil, and absorb rain and oil. Traditional fabric shell holders degrade over time, leading to loose retention and lost ammunition during movement through dense brush. The Midwest Industries Universal Shell Holder (MI-USH) resolves these staging drawbacks by offering a rigid, precision-machined aluminum ammunition carrier that mounts directly to any M-LOK compatible handguard or modular stock section.
Machined from lightweight, high-strength 6061-T6 aluminum and finished in a durable matte black hardcoat anodizing, the MI-USH features an adjustable tension design engineered to securely hold large-bore rimmed and rimless rifle cartridges ranging from .357 Magnum up to heavy .45-70 Government loads. The integrated internal retention mechanism ensures rounds stay firmly seated during rapid movement and heavy recoil while allowing smooth, positive manual extraction during tactical reloads.
Designed for seamless integration onto modern M-LOK lever-action handguards, PCC forearms, or chassis systems, the MI-USH keeps ready ammunition indexed in the exact same spot every time. Upgrade your modular rifle build with battle-ready aluminum shell retention for faster follow-up reloads in the field.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Direct mounting compatibility with any standard M-LOK slot interface (occupies 2 M-LOK slots). Accommodates straight-wall and bottleneck cartridges with body diameters ranging from .357 Magnum / .38 Special up to .45-70 Government (including .30-30 Win, .44 Magnum, .45 Colt, .410 Bore, and similar rimfire/centerfire dimensions).
Installation Sequence:
- Safety check the firearm, cycle the action, and physically/visually inspect the chamber and tube magazine to verify an empty weapon.
- Align the M-LOK T-nuts with two adjacent M-LOK rail slots on your handguard or stock chassis.
- Insert the T-nuts into the slots and rotate screws clockwise to ensure T-nuts turn 90 degrees and seat perpendicular across the rail lip.
- Adjust shell tension screws if necessary to establish your preferred retention force.
- Torque M-LOK screws to manufacturer specifications (typically 30–35 in-lbs for metal-to-metal contact). Load test cartridges to verify smooth removal under field conditions.
