Hi Don, yes! That is the Mauser custom blade from Brownells.... It works out well for you as you have the adj. rear sight mounted on the rear toggle... You would need to lower it some, and profile and shape correctly for a Luger rear sight... But, the main problem with that particular sight is the cost $25.00 each!!!

... That is more then I usually make on most of my barrel projects...

.... (see profitability / feasibility study!

) also, once cut for the Mauser blade.. there is no going back... Neat shooter Don, you need to print that baby on paper and see what you can hold for a group... Inqusitive minds want to know! best to all, til...lat'r...GT....
