Recently I have been in touch with Jim. He is retired now, so doesn't make the Japanese MG parts. I have 2 of his Type 99 magazines, and just the 7.62X39 barrel. I lack the AK magazine adapter and the flash hider for the 7.62X39 conversion barrel. If anyone has those to sell, please contact me. Richard You can either use the adapter or do like the Chinese did and weld a wedge on the back of the AK mag catch and a lip on the front. Have done it both ways for people its pretty easy work all things considered.
