This is not a lee enfield by any stretch of the imagination.

hHnnngnggh. It looks like it should be an m-14 but the concave finger slot in the middle of the body is usually seen in Russian guns.

It looks a lot like an SVT-40, but they come with a barrel shroud, and this doesn't...

Looks like a standard issue Gallian rifle to me.

What dragnfly said. If you compulsively attempt to identify this fictional weapon using real-world catalogs, you will go bald and your nipples will fall off. I say this as your friend.

Unless it's called Lee Enfield in the fiction, I'm taking the tag off.

To me, it closely resembles the Gewehr 41, with variations on the stock and the muzzle

The indentations on the magazine makes it look more like a G43/K43 than a G41.
