  1. Deven (verified owner)

    Just like all MKM products, the fit and finish of these extensions are incredible. The design is intuitive and installs very easily on the B1r magazine. Magazine tension is excellent with the supplied spring. My only concern at this point is the the geometry of the extension interferes with my mag release. The extension is engineered with the captured clip on the rear to prevent it from sliding off. This makes the extension protrude approx. 1/4″ off the back of the mag. I am using a KRG Bravo chassis and the mag release hits this protrusion, keeping the mag from seating properly.

      Hey Deven,

      After having some folks running their Bergara in a chassis we were informed of the mag release clearance problem.

      We are updating the design currently, hit us up and we’ll swap you!

    These mag extensions are so much better than what’s currently out on the market. These are so simple to install and work extremely well. Don’t hesitate to buy one if you on the fence about it.
