While there are a number of methods used for the purpose of securing the magazine in the AK, none of them appeared to securely accommodate the wide variety of AK magazines in the marketplace. Challenges to consistently having a snug fit for your magazine across a variety of AK models from different countries & factories include:
The position of the magazine lug varies between manufacturers.The shape of the magazine lug can vary.Common latch release mechanisms tend to be sharp on their single point of contact which can wear on the magazine lug itself creating irregularities
Lack of guide stops
All this creates a situation where some magazines wobble from side-to-side in the magazine opening.
M + M, Inc. designed a solution to the AK magazine wobble that provides an easy fix at low cost.
This is achieved by:
Incorporating a flat surface many times larger than the single edge contact point of the previous designs.
Angling the flat surface so that the leading edge is shorter than the old designs and will accommodate magazines with lugs in slightly differing positions.
The existing latch/release mechanism on AK rifles is typically riveted in place at the factory. Many AK owners do not have riveting tools. The rivet serves not only to retain the latch/release lever mechanism in place, but also as it’s pivot point.
Replacing the old latch/release mechanism is as simple as removing the old rivet and putting the new Magazine Release Lever (MRL) in place. Where the old lever was riveted to the trigger guard, a pin and “E” clip serve as the new hinge and secures the MRL in place.
“This product is for use on AK-47 rifles and their variants that use standard Mil-Spec AK-47 magazines. AK rifles have been manufactured since the 1950’s in various models, configurations and by various manufacturers worldwide.
No guarantee is either expressed or implied that the MRL Kit will work with every single AK rifle.”
