* 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).

🛠️ The Experience
Initially, I ran into a small snag with the lifter sticking right out of the box. Mechanical parts can sometimes have minor hiccups, but what really matters is how a company handles it—and this team blew me away.
🤝 Top-Tier Customer Service
I reached out to customer support via email and was contacted by **Wesley**. He was incredibly responsive, professional, and didn't make me jump through hoops. Instead, he diagnosed the issue and sent out a replacement right away without any hesitation.
🚀 Performance Update: Smooth as Butter!
* **Easy Install:** Putting the new part in was an absolute breeze.
* **Break-In Period:** After a quick and expected break-in period, it has worked perfectly.
* **Current Status:** It is now running **smooth as butter**!
**The Verdict:** A great product is only as good as the company behind it. Thanks to Wesley's fast action, I am a thoroughly impressed and loyal customer. Highly recommended!
Installed on my Maverick 88. Hoping to cycle 3 in, 2 3/4 in, and 1 3/4 in. Oly can do 2 3/4 in and 1 3/4 in. 3in get stuck cycling. Still better than stock.
Hi Gary, sorry you had trouble cycling 3' shells. Normally any issues with 3' or Minishells will clear up after you run the break-in procedure. Let us know if you did that already and are still having problems.
Relatively easy to install and a great way to improve my 590A1’s versatility. Feeds shorties and a mix of shorties and regular sized 12 gauge shells now. Thank you!
Would not run on federal kept getting jammed between the lifter and top of reciver switched to agulia seems great
Sorry you had trouble with Federal Minishells. Not sure if you ran the break-in procedure beforehand, but if you ran the Federals first, it would be worth trying them again now that some rounds have been cycled thru the gun. Let us know if you continue to have issues.
I haven’t shot it yet with new parts but I did cycle 1 3/4”, 2 3/4” and 3” shells through it just to see how it worked. It performed without a hiccup. Definitely excited to see how it functions long term.
