chamber chamfer

[Geno]

Any advice out there for reaming out the chamber on my mark 2? Just sort of want to deburr it a bit. The edges of the chamber are so square and sharp, its affecting feeding. Dont want to spend 120 bucks on pro tool, what have you folks used?

You can use a cratex rubber abrasive point on a drill. They make some in a bullet shape that screws on the end of a threaded mandrel. You will have to make an extention to get it all the way through the receiver though.

Looked that up, perfect solution, thanks a lot.
