    If the 40 ft-lb spec called for a particular length crowfoot run parallel on a particular length torque wrench, then that would be correct. However The crowfoot is usually run at exactly 90 degrees to avoid extra leverage.

    The formula to calculate what to set the torque wrench to follows (example is 18.5” torque wrench, 3” adapter):

    Torque Wrench Length X Torque Desired) = (18.5 x 40) = 740
    Divided by:
    (Torque Wrench Length + Extension Length) = (18.5 + 3) = 21.5 inches
    740 / 21.5 = 34.42 ft.-lbs.

    That’s 16% in this example. Most automotive fasteners expect a 10% variation, maybe firearms are more tolerant.

    Sent them an email inquiring about this almost 3 weeks ago with no response. Would be cool to know since I’ve got over 1k worth of stuff I want to buy from them besides the collars

    We will only see those again if Colt Canada is doing a batch for our friends in the UK. We have asked for them, but no word
    if they are even in production.

    We never had the collars in stock and we never had them for sale. The one on that build was manufactured by a fellow Gun Nut.
    There is a tread about them somewhere.
