    A-TEC A12 is approved for wadded 12/70 ga. ammunition, max 42g. US #2 or smaller shot size. Do not use slugs, reloaded or high speed ammunition.


    Prior to use of the A12, the choke must be mounted correctly.

    • Check that the two front screws and two backend screws are tight and that there are no foreign objects inside the silencer.
    • Check that you have the correct choke by trying it gently by hand in your barrel.
    • Screw the A12 choke all the way to the bottom of the threads in the A12 silencer.
    • Firmly tighten the lock nut with the supplied tools.
    • Screw the A12 silencer with choke attached on to your barrel.
    • Loosen the check nut.
    • Adjust the silencer to desired "clock" position.
    • Tighten the lock nut
