    Question Retention Bolt Torque / Accuracy and Zero

    Has anyone tried a different number of inch pounds and specificly test accuracy and zero hold at different amounts? I've seen this done before on 10/22 and I have done it myself and seen different results. I'm kind of curious if XCR's are significantly sensitive to this within certain ranges of inch pounds of torque.

    Try searching for posts by Devil doc, he has also done some youtube videos. IIRC he says o really crank it down. If you had a torque wrench you could find the sweet spot and then try to do it as consistently as possible.

    I'm with Sig, I'm happy to hit pie plates unsupported. I've switched calibers and barrel lengths from 7.5 to 18". Never too bad out of adjustment and just a few clicks up/down. Never used a torque wrench on it. I have one that came with my LMT multi cal. The LMT is always supper close after swaps.

    Glad to hear it, I'm not that picky either. I've subbed devil docs youtube channel in the XCR-L vid he says 200 to 220 - I'll end up getting a wrench but also wonder how close I can get to that by hand at some point.

    Terra said -long ago- that 250 is the spec, but I had difficulties finding a driver that would handle 250 inch pounds on my smaller-drive barrel set screws.

    She said that 200 was sufficient, and I've got impact drivers that will stand up to 200 inch pounds.
    And yes, I use a torque wrench.
    Do you really think we want laws to be observed? We want them broken. There's no way to rule innocent men. The only power any government has is the power to crack down on criminals. When there aren't enough criminals, one makes them. One declares so many things to be crimes that it becomes impossible for men to live without breaking laws. Who wants law-abiding citizens? Pass the kind of laws that can’t be observed, enforced, or objectively interpreted - and you create a nation of law-breakers.

    What was the field expedient substitute? Was it a 1/4 turn after it was tight?

    That's what I was thinking, Mjorin.

    That's what Alex has said in a number of interviews and demonstrations.
