The Ruger® Mark IV™ 22/45™ has 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.

Should the magazine get stuck, the extended base pad allow for easy pulling from the magazine well for faster magazine changes.

Mag Bumpers
Added Bumpers to all of my mags for my Ruger Mark IV 22/45 Lite. Very easy to swap out the factory plate and slide on the bumpers. Makes handling the mags much easier and they look good.

Good product!
These give a SOLID fit to the bottom to ensure the mag is in place... So good? I bought another 2 packages after the first two!

helpful addition
I struggle to seat and drop the factory mag on my 22/45 with the factory base plates installed. I tried these and love the smoothness that they added to my gun handling with this pistol. My thick palms tend to catch and rub on the back of the factory plate, but these slip right out when I press the magazine release button without having to shift my grip on the frame. Plus they stick down below the frame bottom making heel-slap seating easier and they can be grasped to pull out a mag easier if there is a problem holding it from dropping out.

Great product!
Does what it’s intended to do! Gives a great look and feel when reloading. Note item is plastic but doesn’t effect functionality. Personally would like to see rubber made. But still loving them and super affordable

Magazine bumper
Most other items I have received from Tandemkross have fit well. Machined metal parts that I have purchased were fine. First two bumper pads one fit great, the other not even close. Contacted them they said they would send another set that were 'fitted'. Second set neither one would work. If you don't care to spend the time and effort to modify. ( right angle die grinder and abrasive pad) you can make them work. Obviously don't want to remove too much material so take a little off and try. After several times they fit ok. Just a little frustrating to pay that much for two pieces plastic and then have to make them work. I believe there is no Q/C on these parts.
