    Didn't see a thread about these, but saw SAC post them. Price is reasonable, features are welcomed, might actually be a much easier upgrade path for the build i'm currently working on than losing my ass on my 5R barreled action and going custom. Price is 369$, does require fitting, but overall much cheaper than trying to bring a 700 up to speed with lots of mods.

    -.695" bolt body O.D. with a larger O.D. behind bolt lugs and in front of the bolt handle to keep the bolt smooth, but locking up straight.
    - Springless M16 style extractor. Same on GA Precision Tempest actions.
    -Threadless bolt shroud. Adjustable firing pin assembly.
    -5/16 x 24 threaded handle to use your own knob if desired.
    -Unique fluting.
    -NIB-X coating.

    Right?! I saw a design similar to this from LRI a while back (it looked exactly the same) and I'm so glad these are coming to market. They look like great replacement bolts.

    Thought I saw LRI offering some as well a while back but dunno what happened to them. Now that you say that they did look very similar, though i don't remember if the supplier was Mack Bros or rather they were proprietary from LRI.
     
    They were Mack Bros, Same bolt LRI is offering. LRI and Mack are neighbors. Don't think there shipping yet.
