this is the hard part.

the palmer barrels are not the same size at the barrels the UMS makes the adapters to fit on. if you can accurately measure the OD of the barrel, then the UMS can make one for you at this dimensions. but you will have to realize that YOU measured it an YOU told them how to make it. if its wrong its YOUR fault. understand?

so what else can you do? the best way is to send your barrel into the UMS. then it will get a perfect fit UMS adapter for your barrel. email the UMS shop through the store home page and contact Britt about this. its probably the preferred method for him also.
