Hey there, was wondering if anyone had any knowledge on older BM59's. Most everything I've found online is directed toward ones with the Beretta stamping on them, mine is a CAI. Most of the info I found about the CAI imports were that they were trash. If you've got any details about these I'd love to hear about it, I'd like to date this if possible, and I don't want to believe all these were trash. Thanks any info is appreciated.
