I seem to have a thing for slightly unusual, orphaned military arms, so I bought a Spanish CETME-L rifle in 5.56 mm from the online retailer linked below. It arrived, and it's beautiful. It's made by Marcolmar of original Spanish and US made parts. It functions, handles, and shoots extremely well. Reviews can be found by searching Google and YouTube. A very similar rifle can be had from Hill and Mack. I figure I'd get one while the getting is good, since it's rather doubtful that the EU and UN will allow much more in the way of military gun parts sales.
