Important:

Recommended Use

Ensure the firearm is completely unloaded before beginning maintenance. Fully engage the wrench with the magazine cap screw or firing pin bushing before applying slow, controlled pressure.

Avoid using excessive force. Components that are seized, damaged, or improperly fitted may require assistance from a qualified gunsmith.

Two Maintenance Tools in One

One end of the SliX Slot II Wrench is shaped to securely engage compatible Uberti magazine cap screws, helping reduce slipping and damage to the screw slot during removal or installation.

The opposite end is designed to engage compatible 3-pin firing pin bushings found on many Browning and Stoeger double-barrel shotguns, providing a compact and convenient tool for two common firearm-maintenance applications.

Whether you are maintaining an Uberti lever-action rifle or servicing compatible Browning or Stoeger double-barrel shotgun firing pin bushings, the SliX Slot II Wrench provides the precision fit, leverage, and control needed to make maintenance easier while helping protect your firearm from unnecessary damage.

Great quality.
Mark Weger - 11/03/2025
Great quality wrench. Works perfectly.
Great tool, but I still ruined the mag cap screw
Allen - 10/16/2025
I had a stuck steel magazine tube cap screw in my Uberti 1866. This tool allowed me to remove the stuck cap, but I still ruined the slot in the cap. Luckily, I had also ordered the Slixsprings brass replacement mag tube cap screw which looks great
Perfect for removing that stubborn magazine end cap
20 gauge - 07/27/2025
Fits the slot on the cap perfectly, either along the axis or perpendicular to it. A necessary tool for maintaining this rifle without munging up the cap slot. Mine had been on for over a decade - perhaps since built - and it would have been impossible to get it off without a special tool like this.
Magazine tool
Wiley Jack Hammer - 06/08/2025
These magazine tools always work great and they keep you from buggering up the end cap.
Important to have one …
Magazine removal tool
Frank Lembo - 05/28/2025
Works great did everything I expected to do thank you very much for your prompt delivery
Not so good
Don Logan - 08/11/2024
Wrench blades for Magazine cap were too shallow and one broke off after a couple of uses. The Firing pin wrench was supposed to fit "most" stoeger SxS models but does not fit my 20 gauge coach gun. The magazine wrench has two sections so its still usable but not ideal....not very happy with this tool. Buyer beware

Reply from Slixprings:

As with any tool if it’s used beyond what it’s designed for or used improperly it can break. As all of our products carry a warranty we mailed this customer a replacement wrench. The following link demonstrates how to loosen those stuck end caps before applying torque on them. How to loosen a stuck end cap.

tool is especially great for getting the mag cap on/off

We have multiples of this tool - one for each cleaning kit (home, travel), one for the gun cart (that gets used by others too), and at least one extra when the tool is misplaced. It's the best way to get the mag cap off/on.

OL' #4 turned me on to your product line Have used your products for years.
Covers all the bases!
Smart Asterisk - 02/04/2024
I have a mix of endcaps on my rifles. With this tool there is not a one that I cannot open. My one suggestion, which is not very reasonable, is to have a storage space to store the bit. This would keep the two important pieces together in my 'possibles' bag.
Firing pins are now secured
Black_Powder - 01/30/2024
Saw at a SASS match, been hoping for years to find something to tighten my Stoeger firing pins, it worked great.
Works As Advertised
Whiskey Tango - 01/20/2024
Purchased this along with the brass magazine cap. Works as advertised. Well made quality product.
