UMP stock and HDPS Stock Block B

638 Views 1 Reply 2 Participants Last post by  S5TIIOwner
Anyone have issues fitting the factory UMP stock to the HDPS block B? I just picked up both and the hinge on the stock is slightly taller than the hinge gap on the aluminum block. I know I can file the stock hinge, but wanted to know if this is normal. TIA.
