Race Gun Kit for Ruger® MKIV™

Bought this kit on an impulse as soon as I got my MK 4 home and had done a little shopping around online. Very glad I did! Huge fan of the flat trigger, which has great pre-travel and over-travel adjustment, as well as the oversized bolt handle. I can easily see the quality and care put into this kit and will be getting further MK 4 upgrades shortly. - Happy Customer

Tandemize your Ruger! The trigger feels better than it looks.

This kit provided a dramatic improvement in the stock configuration. Immediately noticeable was the lack of getting my fingers pinched and rubbed raw by the bolt. The trigger shoe lends itself to a more consistent and crisp pull, and the magazine release button eases the process for quick reloads. The installation tutorial was all that I need to install the parts of this kit easily. I highly recommend the Race Gun kit for any Ruger IV owner.

Recently modified my Mark IV with this kit. Easy to install and great videos for a guide. Took to the range love the new trigger, halo, and mag release. The only issue is the operator related, the extended mag release can be easily hit if care is not taken.

The halo charging ring is a game changer; I no longer feel like working the slide is a test of manual dexterity. Seriously, it installs in minutes and you’ll wonder why it wasn’t part of the gun all along. The Victory Trigger: I spent a couple of hours with a friend whose fingers are smaller and spatial skills greater, and it was well worth it. And btw, there’s a detent spring that can and did go “boing,” so watch that. I used clear nail polish instead of blue thread lock to secure the adjusting screws, and it was a good call, as I had to readjust the over-travel screw. I applied the nail polish with a toothpick and removed it with a Q-tip.
