"Checked the crown and found two small chips and decided to try this kit. IT WORKS GREAT. It lapped out the chipped area and accuracy now is fantastic." - Customer Email

Rifling consists of grooves cut or formed in a spiral nature, lengthwise down the barrel of a firearm. The lands are the raised areas between two grooves. When barrels are manufactured, they start out as a solid rod of steel. A hole is drilled down the center of the rod and the rifling is then placed in the barrel. Tiny micro burrs will form on the barrel muzzle after repeated use or dropping the muzzle on the ground. This is a great way to fix or maintain the accuracy and integrity of the barrel crown. Rifle Bore Lapping is a much more involved processs and is not the objective with this kit.

Worked Great On My Ruger Revolver

Lapped the crown on my Ruger SP101 in 327 Fed Mag. The gun was pretty rough cut from the factory & now looks much better. This product worked exactly as advertised.

that can bring the crown back to life on a couple of my older rifles and this is it. Not looking to cut a crown just touch them up and this is the tool to do it. Shipping was great, quick. Will definitely do business with this company again.

Should Have Done This Sooner

Pros:

I purchased the MCARBO Muzzle Lapping Kit to use on a very old Ruger Single Six (22 LR/22 WMR). This revolver easily had a couple thousand rounds run through it over a lot of years. The muzzle crown had definitely seen better days. It takes a while and some patience, but the payoff is well worth the investment. Consistent groups are back to being the norm. At first I thought the accuracy issues were due to my shaky late 60's hands, but I was wrong (again)!

Lapping jig and compound cleaned and smoothed muzzle. Gun is better than new. Professional results and did them myself. Saved big bucks over gunsmith and proud of my home smithing results. M-CARBO is the best.
