UMP Stock Block B came with old style cross pin, washer, and ring???

My stock block B came in today and I was disappointed to find out it came with the old style "cross pin, washer, and sling ring" instead of the newer version hardware that is being advertised by both hkparts.net and Ed @ HDPS. The product description is clearly suggesting that it should have came with the newer style hardware.

HKParts.net description:

HDPS UMP Stock Block

"New latest production HDPS HK USC/UMP Stock Block "B" Type For Use With All HK UMP Factory Or US Made Folding Stocks. Each unit comes with the new push pin design. This is a required part for the HK USC-UMP style conversion. Each part is the latest US made HDPS production part available with the new scratch resistant coating & finish & latest generation upgrades."

From the HDPS website:

STOCK BLOCK "B" - $195.00 for finished stock block and screws. All new Block B's will have the long steel screws with eyelet/flat thumb ends ready (COMPATIBLE ONLY WITH Hk Foldind Stock).


Did I receive an older unit by accident or is the hkparts.net description misleading in terms of which style take-down pin is actually included? Also curious if any changes were made to the actual stock block itself when this new style pin became available or if the improvements to the stock block were made before the new pin came along...not sure if I should exchange it for a completely new unit w/ new style pin or if I can simply upgrade the pin.

Looking to get this squared away asap because at this point it's the only thing holding me up from sending it to Tom Bostic for the conversion.

Thanks!
