Well this is one of those threads that will drive lots of discussion so here is my 2 cents.
I bought my first autoloader rifle in 1978 so I have had a bit of ownership experience in regards to these types of firearms as well.
Some of the rifles are:
M1 Carbine 30 cal
Mini 14 .223
SP1 AR15 .223
Chinese SKS D 7.62X39
Russian SKS " "
Type 56 AK .223
M1A .308
M1A Shorty .308
CAR15 5.56
I love the Bullpup design but when I have handled them they all just feel ackward. What I mean is the safety, mag release, and charging all seem to require unnatural movement....
The rifles I listed above all have the same challenge except for the CAR 15. The CAR just feels right, shoulder, hand, sight picture, no rocking a mag into the gun, no reaching up to charge the weapon, just please the mag release, slide in a mag, press the bolt release, away you go!!!
I do love the new designs but would I choose one for a SHTF grab and go gun. nope. Would I choose a .308, a 7.62x39, nope.
A 5.56, yup.
Why, simple it takes the same ammo our Forces use. Factor lower recoil, faster on target shot placement, flat shooting, carrying more ammo and mags it just makes sense. Did I mention I also have a CMMG rimfire kit drop in conversion? Yup why would I want to use loud overpowered centerfire ammo for small game and besides rimfire is quiet compared a centerfire round. Ever think how much rimfire ammo you can carry? Ever think what good a 7.62 does you when you run out of ammo? Would rather use a club or a rimfire if you were out of the big stuff. Ever think where you get spare parts from? Ever think how common AR parts are?
I am down to my CAR 15 now, why? It has never jammed, is balls accurate (I only shoot to 100 yards as seriously most shooting will be 7 to 100 yards anymore you semi is going to drop from your hands thanks to a bolt action way out there).
Practise doing double taps, mag changes, charging, sight picture, and the AR will be it.
Lots to think about here but really do some thinking and try to resist doing the hip in thing as if you are in a SHTF scenario you better be good with your weapon.
