    MKA-1919-XN drive block
    • We have began seeing some drive block breakage in high round count guns, usually 2-3000 rounds, a few earlier.
    • If you are a competition shooter or other high round count shooting, you need to check your drive block for cracks.
    • A broken block won't normally damage anything else, but will turn your gun into a single shot
    • Our block is made of billet high tensile steel, it has about twice the material in the break prone area as the factory block.
    • REQUIRES very slight, simple and easy carrier modification to fit correctly.
