I got 2 in today for my H&K 51. These are RDTS Manufactured from 1960's German Mags and Date coded in the 60's. Loads easy no loading tool needed! Actually holds 40+ rounds! We've produced these since the 80's! Very nice mag for your full-autos. Guaranteed to load easy and function 100%.
I doubt that I'll shoot a whole lot of .308 thru it. The 40 rounders are much cheaper then any Beta mag and only 10 rnds less. When I was telling Ralph @ RTDS about the conversion he said good deal.
Tomorrow I send Ralph my H&K SP-89 for a transformation into MP-5K/N.
