I want to begin learning how to pick up on problems and then fix them. I figured I would try and see what the most common problems and what you do to fix those problems and build a good foundation before I go onto complex situations. So what are the most common problems and ways to fix them in the AR platform world?
Thanks.
God Bless.
Learning to correctly clean and lube the platform, and what correct solvents to use doing so.
Short of that, go over the read this before posting tacked thread to start head dive in the rabbit hole of trouble shooting.
Also, learn this cover to cover as well.

Once you get all that under your belt, then you will at least have the grasp to wade into the short end of the pool of troubling shooting on basic concepts of easy to solve problems.
Thanks for the reply. I will get right on that.

Most common program is failure to feed, and 70% of feeding problems derive from bad magazines. Magazines have a service life just like any other part, and will wear out in time. For some reason, people never throw out their old magazines, even when they know they are no good.
