    How about the BCG on the M110 vs MWS ?
    You guys are nice to LMT, that much I know. I'm sure it goes back and forth.

    Our 5.56 (E3) bolts are pretty different than anything else out there in the 5.56 world. Rounded lugs for reduced stress risers in the bolt, reduced cam pin hole for a stronger web, repositioned extractor pivot position for better mechanical advantage on the extractor, and more reinforcement on the lugs beside the extractor. 20k bolt life on short barrel suppressed guns (yeah, springs still need to be changed at their normal intervals).

    The SR-25 and the MWS bolt carriers were very similar, but then both took diverging but similar paths. The lug dimensions are close enough to at least be nominally cross-compatible. LMT does good stuff, I hold Carl and his crew in high regard.

    "Sandcutter" makes me think of certain FAL bolt carriers that had "sand cuts" in them.

    That's pretty much the origin.

    For those reading, I have consistently observed Jack Leuba go out of his way to take care of KAC owners.

    We're fortunate to have someone like him to help us out.

    I'll second that. I've exchanged a few emails even before I was a KAC owner - his consistent behavior is one of the reasons I am.

    Yup, also agreed. His posts on here are a big part of the reason that I have one upper and have plans to buy at least one more plus a few suppressors.
