I just bought a M1 Garand 30-06 made by CAI made in USA. It is stamped on left side of reciever instead of the rear. I had heard they are newer recievers with Milsurp parts. Basicly a parts gun. It looks like it was fully reparked but the stock is waisted. Does anyone know any info on these like: Are the recievers good? safe to shoot, anything will help. Also some parts are stamped BMB which I heard was a Danish mark? Please let me know. Thank you. John
