The Tandemkross MarkPRO Magazine Bumper for the Ruger® Mark IV™ 22/45™ helps you seat the magazine consistently and positively in the magwell. The flush bottom of the factory Mark IV™ 22/45™ magazine means you sometimes don’t push the mag fully home on the first try. The result: your pistol won’t chamber the first round - a serious handicap during competition. The MarkPRO prevents that and also gives you something to grab to quickly remove an empty mag from the gun. Tandemkross molds MarkPRO magazine bumpers from tough DuPont Zytel® nylon polymer that is pretty much indestructible and has enough compressibility to protect your mag from damage if you drop it on a hard surface.

• Makes mag changes much faster & easier
• Helps ensure you don’t lose precious seconds during timed competition
• Easy to install & remove
• 2 bumpers per pack

Tandemkross’s MarkPRO Magazine Bumper for the Ruger® Mark IV™ 22/45™ attaches quickly to the bottom of the factory mag in seconds with the included Phillips head screws. You’ll have time left to try saying this three times fast: "rubber baby buggy MarkPro magazine bumpers!"
