Thread: A-Tec Moderators

    A-Tec Moderators

    I have two A-Tec moderators for sale. One in .243 (around 30 rounds through) and one in .308 (around 40 rounds through), both have 1/2 UNEF threads. The A-Tec is strippable and over barrel. Excellent condition. Each 150.00.
    If interested get in touch through the forum.

    i have a sako 75 in .308win
    and looking for a moderator
    what rifle did you have the .308 moderator on ?

    price seems reasonable to me
    just wondering if the .308 you had the mod on will be the same thread as mine

    If the Sako came screw cut from the factory then it would have a Metric thread normally either 14x1 or 15x1 depending on the calibre.

    Be careful lads, There are two similar threads - 1/2"x25 UNF, and 1/2x28 UNEF, they wont interchange.
    I'm sure deerman will be able to keep you right.
