Most Helpful Positive Review Magazine Base Extender
Great little way to extend the 10/22 magazines so you can more easily extract them from the mag well. True most of the time the mags just drop out, but there's always that one time, in the middle of a Rimfire Challenge stage, with everybody watching, where on of those little boogers won't shake lo...

Most Helpful Negative Review Do not buy these
Just up front, TandemKross usually makes great products. I have a few of their comps, and I love them. Unfortunately, these are complete garbage. They have zero attachment to the base of the mag, and they will shake off before you ever put the mag in the gun. I thought maybe the first was just a bad...

I was having loading issues with my Volqartsen Summit bolt action 22lr…after adding a Kidd mag plunger and tandemkross spring..this mag bumper did the trick.., only ruger mags with this bumper will reliably load…easy fix to an expensive and frustrating problem

Must have for a Ruger Precision Rimfire Rifle

by Dave, Verified Owner from WA, United States Written on February 1, 2025
A an absolute "must have" for a Ruger Precision Rimfire Rifle. BX-10 mags actually sit recessed in the mag well on this rifle and the extended bumpers make a world of difference when using these 10 round mags. I little tricky installing and bit expensive but worth it. Own lots of TandemKross rimfire accessories and are always high quality.

1st time I’ve bought a tandemkross product I didn’t like. I use a lot of their products and they’ve always been top notch.These magazine extensions don’t meet what I expect when purchasing their products, when installed they have ugly gaps between the two pieces . I would recommend just buying their magazine wish I would’ve just purchased two more of their magazines , because theses going straight to garage can

Pros:
  • Ease Of Use
  • Design & Build
Cons:
  • price
Best Used for:
  • Ruger

Easy to grab

by Beano22, Verified Owner from AR, United States Written on February 2, 2024
I have used these Tandemkross magazine extentions before I bought these from Opticsplanet and knew the product well. They fit on the bottom of the magazine and this makes it easier to grab to load and unload the magazine from the rifle. I use them in competition and have never had any problems with them. They are well made and easy to install. I highly recommend them.
Pros:
  • Easy to install
  • All Hardware included
Cons:
  • None

Ruger 10/22 magazine companion

by Sam, from RI, United States Written on July 29, 2020
Works fantastic. Makes inserting and ejecting magazines simple and fast. Provides an excellent place to secure magazine in hand. When shooting steel plate events, you are able to swap magazines much quicker and efficiently
