The general purpose M4A1 carbine with a general purpose low powered variable works for me since I am not issued a crystal ball to tell me what parameters of the fight will be.
MS makes a very important point--we don't know what the fight will look like.
I am just a tax lawyer from Orygun, but even I can figure that out.
None of the guys in the NRA's "Armed Citizen" files got the fight they envisioned.
Nevertheless, I continually encounter guys who "know" what the "situation" will be.
Both ourselves and our tools must serve general, not special, purposes.
I see this specialization problem everywhere.
The survivalist who cannot swim--He is prepared for the end of the world but will can't survive a fall into 5 foot deep ditch.
The Fat Martial Artist -- He knows 43 different ways to break a board but he cannot run 1 mile if required (flash flood, chemical spill, whatever).
The "Gun Nut" who owns a different rifle for each combat scenario but has not trained with any of them.
Each one of these guys has a limited, predetermined scenario that he is training for. Sadly they odds are EXTREMELY high that real life won't meet their predictions.
That being said . . . . . . .
(sheepish grin) . . . . .
My AP4 (a DPMS M-forgery in 308) wears a 6x42 HEAVY DUPLEX Leupold. Target acquisition inside a room is best described as "sucky", but it can be done.
Its "mostly" a General Purpose AR, but first round hits at 300 yards (prone or kneeling with a rest) are pretty easy.
Good Shooting.
