I have a minty EAL, I've been offered anywhere from $75 to $750. the latter by a fellow that knew what it really was. Most people just think they're nice bubbas.
The EAL rifles were built in two versions, the military versions have the tangeant style two leaf rear sight on the barrel, with 5 round magazines and the civilian versions look like the one in the picture, wil the flip type sight on the action and the 10 round magazines.
There is a lot of conjecture as to the use of the military EALs, Supplying the Rangers was a secondary consideration from what I've read. Some were used in aircraft as survival rifles and the rest were put into storage until they were issued to the Rangers. I don't know when or if these rifles were actually sold into the surplus market or a few managed to leak out of the system.
I talked to an old Hercules pilot that said there were always a couple on board, but were never to his knowledge used. They were given rudimentary training with some very well used EALs and he said the muzzle blast and recoil was nasty, makes sense. There is a writeup on EAL rifles and versions in Skennertons book. bearhunter
