The Mini-Pro Lifter and Cartridge Arrestor System is the next step in the evolution of short-cartridge cycling capability.  Taking the success of our Universal Cartridge Adapter and 590S Cartridge Arrestor Upgrade Kits to the next-level, Mini-Pro is not an adapter; it is an OEM-like solution that addresses the heart of the shotgun's functionality, where the entire factory lifter/elevator is replaced with our Mini-Pro Lifter and 590S Cartridge Arrestor System.  This means you can essentially upgrade any Mossberg pump-action 12-Gauge shotgun with a 3" receiver to a true 590S-like configuration.

The Mini-Pro Lifter is constructed of hardened steel and blackened to match the factory finish.  The cam profile has been optimized to accommodate minishells, and the bolt carrier rails have been polished to smooth out the action and provide a "broken-in" feel.  The legs of the lifter are slightly biased in the open position to ensure plenty of residual pressure is applied to the pivot pins so they can't jump out of their respective holes if the firearm is dropped (see this video starting at minute marker 4:25 for more info: https://youtu.be/87XSOnQrCYg).

The Cartridge Arrestor is exactly the same as our 590S upgrade design and is constructed from vulcanized thermoplastic rubber.  The follower is machined from solid 6061-T6 billet aluminum and is finished in a hard, safety-red anodized coating.

This system is compatible with any Mossberg 500, 590 or Maverick 88 pump-action 12-Gauge firearm with machined grooves in the receiver.  

*Please note our Universal Cartridge Adapter is forward-compatible with the Mini-Pro System with a simple modification.  If you already own the Universal Cartridge Adapter and would like to reuse it, you will only need to purchase the Mini-Pro Lifter. 

**The Mini-Pro Lifter, Cartridge Arrestor and Magazine Follower are optimized to function as a system, however the factory and other aftermarket followers may function as well for those that do not wish to use the follower provided.

***A short break-in period is recommended for the Mini-Pro Cartridge Arrestor, cycle 4-5 magazines of 2-3/4" cartridges thru the firearm before trying to feed 1-3/4" or 3" cartridges (can be dry-cycled if you have a safe place).
