* ATTENTION * If you already own our Universal Cartridge Adapter and would like to modify and reuse it with the Mini-Pro Lifter, please choose the Lifter Only option. For new users or those that don't want to modify their original adapter, please choose the Mini-Pro System kit, which includes a modified adapter.
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 most Mossberg pump-action 12-Gauge shotguns with a 3" receiver to a true 590S-like configuration (not compatible with 590R).
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 refer to the picture or the installation video below to confirm your firearm's compatibility, but we've never seen a Mossberg pump-action firearm without these grooves.
*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. See video for more details.
**Apply a thin coating of gun oil to all lifter surfaces prior to installation.
***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).
works perfectly.
Wanted to take a minute to thank Wesley and the team over at defender tactical for their fantastic customer service , I had an issue with my 590 jamming with the lifter at first but they promptly sent me a replacement that cycled perfectly and really went above and beyond to make sure I was happy with my purchase . Thanks again guys you rock .
Installed the Mini-Pro Lifter and Cartridge Arrestor in a Mossberg 500 and a Maverick 88 shotgun. Both installations were easy, and now both guns can mix & match different-sized shells without the delay of installing/removing plug-type min-shell adapters.
This kit does exactly as advertised. It basically turns your stock 590 into a 590S. While the OPSol adapter is great for what it does, this kit means you can use shells from 1 3/4" all the way up to 3" without having to remove an adapter when you want to switch from mini shells to normal size shells. The parts are well made and fit perfectly. Easy to install as well with some great videos out there walking you thru the process. Not only that but their customer service is top notch. I had an issue with one of the parts of my order (not all parts are perfect all the time in this world) and they took care of it the same day I contacted them for assistance. All in all a great product from a quality company. Couldn't ask for anything better!
I installed this kit on my Mossberg Retro. I can’t recommend this enough. The new lifter actually sits better in my receiver. The factory was favored one side and was showing wear on one side. This sits in centered and cycles smooth. The follower is much quieter than the factory that was shrieking loud. Extremely happy with this setup
