    Boy, I would have failed the pop quiz.

    yeah, for trigger spring that should be hammer spring. For ejection port block that should be brass deflector. For gas rod spring that should be op rod and recoil spring. My mind slips about as much as the transmission in my beater leaking oil in my driveway!

    sounds like the 300blk kit will be spendy.

    I actually run with the original 5.56 spring with both kits, but use the 7.62x39 deflector for both. Only observations on my end is 5.56 brass ejects at 5:00 instead of 2:00 and have the occasional lite primer hit on real hard russian primers. (1 or 2 every 200 rounds)
