I do love me some vintage firearms.
Basically, anything from muzzle loaders up to, say, the Korean War.
I used to shoot with a group that had some FFL SOT types. These guys knew I was a WWII buff, so on occasion, I was treated to a Class III toy.
Thompsons (a lot of them), MP40, BAR, M3, M1919, Vickers, Maxim, etc. And some newer stuff like MP5K, a bunch of AK's, a full auto Ruger 10/22, an MG42 that was modified to us an M16 lower receiver, an M14E1, and some kind of short 308 cal that was LOUD!
There were some muffled goodies every now and then.
Uncle Sam let me play with M16A1 and A2 and a little bit of time with the M60.
I don't get out much these days, but I used to shoot a lot.
