    Dumb question: Baking Sig FCU to cure loctite?

    You can speed up cure time---but, you do you with a 320-AND adding 2 screws and thread locker to that mechanical mess. You may have an innocent question or are baiting since it's a 320

    Scope ring height

    Heck, you have some running 1.93 on AR's now! The 1.5 is not that tall at all, pic below, even on a bolt gun.

    Bushings and expander mandrel? .223 to start

    Lake City, the first lot/rifle will be 04 and the lot I will use on the other 2 is LC12, annealing each firing.
