Competition shooters love the Ruger Mark series, and these Maximus Plus 1 followers are built specifically to give you that extra round advantage. Instead of being limited to 10, you can now load 11 rounds into your factory magazines. Most rimfire matches allow you to start with 11 rounds, so every bit of firepower counts when you're running the course.
The secret is in the profile. These followers are engineered to sit just right in Ruger MK series magazines, letting you squeeze one extra round in without sacrificing reliability. They're constructed from Zytel, a tough polymer that holds up through thousands of rounds without degrading. That bright red color serves a real purpose too: you get instant visual feedback that your magazine is empty, which matters when you're focused downrange.
There's no gunsmithing required here. You simply disassemble your magazine, swap out the factory follower for the Maximus Plus 1, and reassemble. The whole job takes minutes with no special tools. These work with Ruger MKII, MKIII, MKIV, and 22/45 models, and they're compatible with factory base pads as well as aftermarket bumpers from TANDEM KROSS. One package includes two followers, so you can upgrade a pair of your mags at once.
Keep in mind that rimfire ammo varies slightly in rim diameter and overall dimensions. Some loads feed the eleventh round effortlessly, while others might need a little patience getting that last round to seat fully. A few people find that cleaning up the edges inside their magazine tubes helps with smooth feeding. The TANDEM KROSS website has videos showing how to "slick up" your mags if you want optimal performance.
Yes, these followers work with Ruger Mark II, Mark III, Mark IV, and 22/45 models. They're compatible with factory base pads and TANDEMKROSS aftermarket bumpers. The followers should work smoothly with any generation of the Mark series, though you may need to lightly polish the magazine tube interior if you encounter resistance loading the 11th round.
No. Simply disassemble your magazine by removing the base pad, spring, and factory follower, then insert the Maximus Plus 1 in its place and reassemble. The drop-in design takes just a few minutes with no special tools required.
Most loads will feed the 11th round without issue, but rimfire ammunition varies slightly in rim diameter. Some ammo loads easier than others. If you experience difficulty getting that extra round to seat, lightly polishing the follower top or the magazine tube interior can help. TANDEMKROSS has videos on their website showing the magazine prep process.
Using both together still maxes out at 11 rounds, not 12. The combination doesn't stack for additional capacity, so pair the Maximus Plus 1 follower with either a factory base pad or any TANDEMKROSS extended bumper pad.
