I am sold on the Glock and AR platforms. Getting into the AR more, although seems like a bad time to ramp up.
Many moons ago I purchased a Glock armorer's course from AGI which was pretty good. It showed me how to completely disassemble the gun and then reassemble it. I also purchased the manual which made me a lot more confident in dealing with it. One reason why I like them so much. I can't seem to find it in other pistols such as M&P or XDs. Then again, I haven't looked to hard.
There is an AR armorer's course being offered in a few weeks. 2 days, 16 hours. I am wondering if I really need to know how to completely strip down and reassemble this gun. It could be fun, but there may be a shortage of parts for quite a while.
It is good to completely know your platform, but is an armorer's course "needed"? (Crap, I sound like Piers Morgan.) And how would you get a job doing it?
