At a glance:

  • Oversized bumper improves consistency of positive magazine seating

  • Lateral grip pulls make pulling from magazine well easy

  • Zytel® based bumpers offer the ultimate strength and durability

*Includes two base pads per order.*

The Ruger® MKIV™ has quickly become a favorite rimfire pistol among competitive shooters, but the flush surface on the magazine base pads can be challenging for competitors, making it harder to consistently seat the magazine properly and causing unnecessary delays.

The TANDEMKROSS MarkPRO Extended Magazine Bumpers for Ruger® Mark IV™ offers an oversized, textured Zytel® grip, allowing the user to easily bump the magazine into place for positive, consistent magazine seatings. Should the magazine get stuck, raised sides on the extended base pad allow for easy pulling from the magazine well for faster magazine changes.

These drop-in MKIV™ accessories attach to the bottom of the factory magazine without any glue or gunsmithing - installing in minutes! This simple Mark IV™ upgrade is ideal for competitive speed shooters or any Ruger® MKIV™ owner looking to improve the firearm’s reliability.

Supported Models:

  • Ruger® MKIV™ Target

  • Ruger® MKIV™ Hunter

  • Ruger® MKIV™ Competition

  • Ruger® MKIV™ Tactical

*Please note* This part is designed for the MKIV (standard style grip frame only)

I have ordered several items from Tandemkross. Al have been excellent and shipped quickly. But these bumpers are an exception to the rule. They installed on the magazine just fine, but would not allow the magazine to load into my Ruger Mark IV. The product simple does not fit properly. Tandemkross has already sent my a postage paid return label and a promise of a refund. But I must say, I would not recommend this product.

I ordered 2 of these and installed on my mags, all went smooth but they would not lock into my MKIV Hunter as there seems to be a small clearanece issue, I filled the molded plactic bumper on a few of the seams and cleaned up when molded, now they work as intended and Im very happy. maybe 10 mins of hand file gently and the work perfect now

Mr Bill
Just installed on my Mark IV competition with Volquartsen laminated target grips. I was concerned that they might not work with the extended target grips. The bumpers fit the bottom of the grip opening with no problem, with the added benifit of extending the magazine below the bottom of the large heelrest grips.

MarkPro Mag Bumpers
Installed them and loved them. I had bought the bottoms to convert some Mrk III into Mrk IV, wasted my money. Should have gone with these instead. Great and work extremely well with the laminated wood grips.
