TANDEMKROSS “MARKPRO” Magazine Bumper — Ruger® MKIV™ 22/45™ (2-Pack, Black) (1926N0237BLK1 • UPC 769498483145)
Faster reloads. Cleaner seating. Better control. The TANDEMKROSS “MARKPRO” Magazine Bumper is a competition-ready base pad upgrade for Ruger® MKIV™ 22/45™ factory 10-round magazines. This two-pack of black bumpers adds a generous, textured ledge to the bottom of each mag for positive seating on closed bolts, easier extraction from tight mag pouches, and added protection when mags hit gravel or concrete during speed reloads. If you shoot Steel Challenge, NRL22® pistol stages, or simply want smoother range sessions, the MARKPRO delivers the confidence and ergonomics your rimfire deserves.
Why Shooters Choose MARKPRO for the MKIV 22/45
Positive seating on a closed bolt: Extra purchase on the base lets you drive the magazine home with authority—reducing failures to seat and “mystery” malfunctions.
Lightning-fast reloads: A wider, contoured bumper gives you a sure grip for ripping mags from carriers and clearing the well, especially with gloves or sweaty hands.
Drop protection: Impact-resistant construction helps absorb shock and shield the mag body/base when dropped during match-speed reloads.
Ergonomic control: The added ledge doubles as a pinky rest for many shooters, improving wrist leverage and recoil control on the string.
Range & match proven: Designed with competition in mind—durable, low-glare black finish looks professional and resists scuffs.
Great value: Comes as a 2-pack, so you can standardize your go-to magazines quickly.
