Requiem Arms Single Stack to Double Stack Mag Well Jig

Current Stock:

This jig was designed by Requiem Arms for gunsmiths converting a single stack magazine well rifle to standard double stack. It simply sits in the mag well and aligns with the trigger guard allowing the customer to use a simple hand tool such as a dremel tool to complete the cuts. You can also use it as a simple guide and throw it on the mill and complete the cuts that way.

    Worked exactly how it was supposed to, it’s very hard to find reviews on this. It works great. If you have a scope Mount rail you’ll feel the need to notch the Jig out, it’s really not necessary. You can if you’d prefer to tho.

    Had to trim the side to fit over the scope mount bracket but other than that exactly what I needed
