Only 4 of these in stock. I believe these to be early RPB M11-380 steel 32 round magazines. They came out of a large purchase of weapons from SWD years ago. They look to be "anodized" and not blued or parkerized. My suspicion is that they are RPB magazines but cannot find anything to document that. Each magazine has a 32-round capacity. They are all in excellent condition. Price is $65.00 each.
