WTH did I just buy??? I did find some microscopic roll marks that say it was assembled by CAI (and I negotiated the price accordingly). What is up with this cast upper? Anyone seen anything like this before... and.. is the Rhino lining a "factory" finish or did someone really got kitchen gunsmith on this thing?? The price seemed right.... and the bolt gap is .011" (which is in service specs, if I recall), and it lobs lead away from the shooter. I have to admit, I bought it because it looks like such a bastardization of the CETME. Anyone seen anything like this?
