M1 garand is great. Love shooting my bros, and that was the best gun im WW II.
M1 carbine, don't know about the older ones, but my bros new one shoots great, at least to about 200yds. Never shot anything bigger then a coyote though.
I had an Israeli pattern FAL, didn't like it. Got rid of it. Too heavy and bulky.
I like the AR action, and the 6.8 keeps a lighter weight but still more knockdown. 5.56 has a LOT of shortcomings, and I know everyone else who has been in combat knows why....
7.62 ARs are great for longer ranges, but for clearing houses you can't beat short stocking a SAW!!!
