* 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).
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
UPDATE - Wesley reached out the same day and offered several options to remedy the situation. He sent out a replacement lifter. This second lifter had a better and smoother finish than the factory lifter. I installed it and it works flawlessly with a mixed load of 1 3/4 and 2 3/4 brass and steel hulled shells. The mix always had 1 3/4 minis last for the least amount of push from magazine spring.
Most impressive is the speed of and continued follow-up of the issue. They really stand behind their products. I would not have any reservation in purchasing any other products from them and couldn't be more pleased.
ORIGINAL - Same as another recent review. Maybe this batch? Lifter has rough edges compared to stock. Shell stops about an inch out of magazine. I can get it out by flick with finger nail.
I took it out and filed down some, it better but still hangs on last 2 2&3/4 in shells. You feel the difference with both lifters out and just running a shell across it vs the stock lifter.
Sorry you are having trouble with your lifter, I'll contact you by email so we can get it fixed.
Installed in my new 590 ! WOW ! Shot 2 and 3 inch shells with lots of kick ! Not bad , but expected it with shockwave stock ! Put this kit in and tried shorty shells ! Big difference! Smoother to fire & cycle ! No problems so far & do not have to remove to use different size shells ! Just what would you would expect from a Mossberg ! Defender Tactical is the kit for this ! Don’t hesitate to buy ! Awesome ! Thank you & God Bless !
I got my MINI-PRO LIFTER faster than what I was expecting. Got it installed in my maverick 88 but the lifter would not work in my particular gun. It kept binding up and not cycling even after I had worked the action a lot. I reached out on a Saturday evening and was answered right back within minutes. I told them the issue and they knew exactly what was causing it and what needed to be done. The next Friday I had a new lifter that’s running like a fine tuned machine now. I couldn’t be happier with the product or the customer service. I will be buying more products from this company as soon as they get more maverick 88 light rails in stock. Highly recommend company and product for going above and beyond.
