Most Helpful Positive Review Simple and great product
I installed this yesterday with a wee bit of help from the Tandemkross video. Fairly easy except the pin dropped out holding the sear and that was troublesome to get back into place. I would recommend tape on both sides to keep the pin from running out. Once the sear was back in place I used a magazine to hold the sear out of the way to set the mag disconnect in place and all went smoothly after that. Works great. range day this weekend.

Blast shield was a little tricky to install. Make sure you watch the Tandemkross videos.

Convenient

by Gecko23, Verified Owner from OH, United States Written on January 14, 2025
I was looking to remove the magazine disconnect on a Ruger 22/45, and if you just remove the factory disconnect bit you have to shim it because the factory bushing is sized to accommodate that piece. Luckily Tandemkross makes this bit that allows you to skip the extra bits and allegedly keeps your innards cleaner as well. Time will tell, but it accomplished what I wanted so thumbs up.

best first upgrade to my Silencer Shop MK4

by Michael Kennedy, Verified Owner from OR, United States Written on November 6, 2023
This is the second one I have purchased for my Mark 4s. It helps keep the lower clean and I love not having a magazine disconnect. Great product. A little tricky to put in, with that said TandemKross has great videos.
Best Used for:
  • Ruger MK4
