Maybe .... Some 53's are built with the long rear tang ejector found on the HK93/G33 and some are built with the short tang ejector made for later HK53s. Have one of each, the V53P being the long tang and the MM53 being the short tang.
How far from KCR are you located, might be able to make it down sometime this summar and toss in the V53 if you wish to try.
