I don't think the 308 converted MAS 36's have problems, it's the MAS 49/56 semi autos that tend to have problems.
Considering the uniqueness of most
French firearms, I am of the opinion they deserve their own forum. Back when I was heavily into searching for them to purchase, it would have been helpful.
I am no longer actively searching, I have a Chassepot, Gras, Lebel Rifle, Lebel Carbine, Berthier Rifle, Berthier Carbine, MAS 36, MAS 49/56 and two handguns which wouldn't be in a rifle forum.
Only one I'm still interested in would be a Gras in 8mm Lebel but they aren't exactly easy to find. I suppose if a Gras Carbine walked into my life it might go home with me if the price was right. The RTI Ethiopian ones are too expensive for the condition they are in in my humble opinion.
