If you could have any 5 guns.......

[Yournamehere]

Huh, let's see.....

T Series Browning Hi-Power

Ithaca 37 Riot 8 shot (the original version, not the ones they make now).

H&K MP5A3 (dunno if that's transferable)

Colt made M16A1.

FN FAL or British L1A1 SLR, not sure.

Scratched the Colt made 1911A1 because it's not rare, just expensive.

Just for the record, too, Calling the ACR the "Remington ACR" is a bit of a misnomer. While Remington is supposed to build the guns, they (as well as Bushmaster) are owned by Cerberus Capital Managment, and they decided the development and marketing would be taken care of by Bushmaster after they acquired the rights to the design from Magpul. It looks like one of their companies (Bushmaster) did all the work on paper and then they gave the actual grunt work to another one of their comapnies (Remington). So I feel if you're gonna call it anything, it should be what Cerberus decided to call it, due to the development portion of the weapon, the Bushmaster ACR.
