RE: Who taught you how to shoot?
Mine was the Army, learned on the M-16. Then had to relearn on the M-21. the things that work with a m-16 do not work on other rifles. One that got me was puting your nose up to the charging handle on the m-16. When I put my nose up to the reciever of the M-21 it hit my nose hard learned quick not to do that.
