    Default Looking to make a Colt SP1 bolt from M16 Anybody got plans/Drawing

    I have a buddy who has an older Colt and wants to have a SP1 style bot in it. I think you could mill down a M16 bolt to SP1 specs right? Is there a drawing or plans that I could import into Fusion to create this bolt?

    Thanks

    Curious to the advantages or preferences for specifically modifying it to an "SP1" bolt carrier. Simply mill the back end off as required.

    The bolts are the same. Are you referring to the carrier? If it’s because you have a transferable lightning link, awesome. If not, I too am curious what advantage you see in the SP1 carrier?

    I see you are in the Aland Islands. Is this being done for legal purposes? If not, leave it alone, the m16 carrier is heavier and more reliable. The sp1 carrier was done to prevent people from using lightening links, conversions, etc.

    The LL ONLY works with SP1 carriers, not M16 carriers. DIAS works with M16 bolts.
