After a short delay, I have a fresh pipin' hot batch of Automag-to-Autococker-barrel adapters in stock. These, of course, let you use much more common 'Cocker thread barrels in your twist-lock Automag, MiniMag, R/T, EMag or even a Sydarm. They fit all stainless-body 'Mags, right or left side feed, powerfeed or plain, and even centerfeed.
Drop-in, no gunsmithing or mods, go back to using the twistlock at any time. Stainless steel and lifetime guaranteed.
$40 each and Priority Mail anywhere in the US will be $6. Outside the US, email for a quote.
