Thank you for all of the great info I've already found on this forum. My new-in-box M&P 15-22 (DZL serial, black with threaded barrel) is sitting in pieces on the kitchen counter, awaiting better weather. My break-in plan is based on an article I read. Hey, it was on the internet so it has to be true!
- Clean cardboard fuzz and any other debris from the chamber.
- Pull a BoreSnake with a little Hoppe's through.
- Put one round in the magazine and fire it.
- BoreSnake again.
- Put two rounds in and fire once to make sure it doesn't full-auto, then fire the other round.
- BoreSnake again, fire three, BoreSnake, fire four, BoreSnake, fire five, BoreSnake.
- Put the cleaning stuff away and start having fun.
I will be using bulk Federal 36-gr. hollowpoints from Walmart.
Any advice or admonitions?
Is it OK to use compressed air (dry shop air, not from a can) to blow out crud when cleaning? Machinist's textbooks always warn not to do this because it can force stuff into places where it shouldn't be, but of course we all do it anyway.
Thanks again. Looking forward to "kicking some brass" in the sticks outside St. Louis!
