Description

Some lever guns are about tradition.
This one is about control under pressure.

The Marlin 1894 Mad Pig Custom SBL takes the familiar .44 Magnum lever-action and rebuilds it for modern field realities—tight terrain, fast transitions, suppressed or braked setups, and shooters who demand repeatable performance rather than nostalgia.

At its core is the proven 1894 action, now paired with a 16.1″ cold hammer-forged stainless barrel, threaded and fitted with an angled Spade Scepter muzzle brake. The shorter barrel length keeps the rifle quick and balanced, while the brake and soft rubber buttpad work together to tame recoil impulse—especially important when running heavier .44 Magnum loads in rapid follow-up scenarios.

The Mad Pig Customs enhanced lever and takedown system transform handling. Cycling is faster, more deliberate, and easier to manage under gloves or stress. The Midwest Industries pistol-grip stock with G10 insert shifts wrist angle into a more neutral, modern posture—reducing fatigue and improving trigger control during extended use.

Sight acquisition is immediate. A fiber-optic front sight with tritium ring draws the eye in low light, while the adjustable ghost ring rear supports rapid alignment when timing matters more than magnification. Add in the extended handguard with M-LOK, forward QD sling mounting, and nickel-Teflon follower, and this rifle clearly signals its intent: functional readiness, not display-case polish.

This is not a commemorative lever gun.
It’s a working rifle for people who expect to move, decide, and act quickly.

Technical Scope

This rifle configuration is optimized for short-range to mid-range .44 Magnum use where rapid handling, recoil control, and fast sight acquisition are critical. The 16.1″ barrel and threaded muzzle support modern brake or suppressor setups, while the platform’s geometry and upgraded controls prioritize stability, control, and repeatable performance under dynamic field conditions.
