Glad to see that guy, Detachment Charlie bring up the old Enfield, I have heard everything good about the FAL, but speaking for my brother, if I may, He always liked the M-14 far better than the M-16, he was in Nam with M-16, but always said he wouldn't rather had his M14 instead, but like Rifleman 173 said, different weapons for different jobs.
For the money "I" would get a M14, an probably someday I just might.
I think you will probably like all the selection so its a tuff decision, unless you want to sell or trade alot.
