It's not a legit counter bore job done by an amory or gunsmith, but it fixed my mosin's habbit of shooting 2 feet high at a 100 yards. If you just need the crown touched up this is worth every penny.

Good tool

This lapping tool restored my enthusiasm for one of my Mosin Nagant rifles. Badly pitted muzzle crown had shots going everywhere except where they were aimed. After a few treatments with this tool, I’m seeing much improved shot groups.

Have been looking for something

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.

Impressed all around!

From the product shipping the day after I ordered it, arriving promptly, to doing the job as promised! I have a S&W that had horrible burrs on the crown from the factory, some pointed out and some pointed in. This caused shots over 6 inches low and left at 20 yards unless I compensated. Less than an hour, mostly charging my drill battery a few times, and the crown is lapped. Shove a few cotton balls in the barrel to save on clean up, I taped my gun with painter's tape to guard the finish. Thanks Brother!

Just used this to remove burrs on the cutting edge on the sprue plate of a new lee mold. Feels sharper. Will see how clean it cuts.

Nice Touch

Ordered this to go along with the spring kit and polishing kit for a new Ruger SP101. Polished through the cerakote on the muzzle to make a very smooth crown. My "new" SP101 is now way better than it was when I bought it. The videos, shipping and customer service are awesome. Thanks!!

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.

Should Have Done This Sooner

Review

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)!

Silicon Carbide ?

Aluminum Oxide is the correct compound, Silicon Carbide will embed in the steel
