That Should include you, sorry if I sound harsh but you have a magazine fed Semi-Automatic rifle. I get so tired of people who think they are gun people replace the word clip for a magazine... Clips help you load magazines!! Sorry about the rant but I doesn't help the the Cause if you can't properly name the parts of a weapon. I'll not be replying if you chose to send back a negative reply.
What if his rifle is an M1?
For practical purposes it is a difference with rare distinction. Very few people carry weapons that take stripper clips. I liken it to people who use “effect” when “affect” is correct. Yes they are wrong, but not a single person was confused about their meaning.
I'm an avid gun collector, shooter, and military firearms historian. I have guns that take en bloc clips, clips, removable magazines, and clips & removable magazines. I find it possible to know details about firearms and not get my panties in a bunch when others confuse them.
I suggest that you calm down and focus on getting upset about things that matter, and try not to be a nomenclature nazi. People don't need to know what a piston ring is to have a valid opinion concerning the speed limit.
