* 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).

Great customer support and products

I received the mini pro lifter and installed it in my new shockwave, however the lifter was causing the action to lock open. I reached out to Defender Tactical and they sent me a new lifter. Fast forward to install lifter #2 and the same problem was happening. Spoke with them on the phone and they walked me through trouble shooting. Turns out my shockwave was within tighter tolerances then all the Mossbergs that were used for design and production. Defender Tactical explained that a small portion would need to be machined from the lifter flats. Under the authority of Defender Tactical, who offered to do it for me, I sanded/filed 1/10-2/10 mm from the flats and the unit now functions as they designed it to. I was 1 of 2 that have had this issue, per DT. Now installed the unit works great loading and unloading of mini shells. I can’t say enough about how helpful and personable the DT guys were. A true testament to a company that stands behind their products and works to make their customers happy. Support these guys and buy their stuff. Happy Shooting!

Incredible piece of kit

Install is very easy; if you've torn down your shotgun for a deep clean you can install this. The best piece of advice I have is be CAREFUL when you remove the magazine tube that sucker is under quite a bit of spring tension.

Use a generous amount of oil on the lifter and what really helped me was to clean all the gunk out of the lifter holes on the receiver and hit that hole with some oil.

Action is very smooth, cycles every shell length I've tried to put in it. If you've used the previous cartridge adapter this is a great upgrade, you recover the opening of your loading chamber!

Top Shelf Folks!!! 👍👍

My apologies to the folks at Defender Tactical, posting my review just slipped my mind. (Mini Pro Lifter), I believe depending on what day, month or year your Maverick 88 was manufactured it can be a little finicky with the MPL and of course mine was, lol. When I left a message at DT, it took less than 24 hours when I believe it was Wesley that called me back and I explained my problem to him, right away he knew what it was with my pump action getting stuck open and it would've taken a little modification to the MPL but he made it RIGHT!!! And now my pump slide works flawlessly. These folks stand behind their products and that's why if I need anything else for my Mossbergs and if they offer it, I will definitely ALWAYS purchase it from DEFENDER TACTICAL 💯%!!!
Thanks guys! jayNnc

Great product

I love this in my shockwave. Not the easiest to install but definitely not difficult. Just gotta pay close attention to instructional video. Cycles very smooth. And ejects cartridges better now than before. Thanks!
