Ok so I have this bubbaed 93 Mauser that I couldn't get to group inside a 5 gallon bucket no matter what was done . I had heard of these kits so I ordered one so we shall see. I have read online it takes some tinkering so I figure its for me. The kit came today looks well made shipping was very fast. If anyone has built one of these please let me know how it went good bad the ugly.
