Precision Muzzle Crowning by Dave Manson

No-lathe high precision muzzle crowning with use of unique hand tools. For rifles, shotguns and handguns from .22 to .50 caliber, .17 and .20 caliber setups are available as a special option. Separate crowning tool for 12-20 gage shotguns is also offered. Delivers fast, accurate and chatter-free muzzle crowning for all barrels, including the ones with chrome-lined bores. Produces concentric flat and 11 degree target style muzzle crowns in less than 10 minutes on average. No firearm disassembly is required for muzzle crowning and no additional equipment and special skills are needed to use these tools. Crowning cutters use very long lasting
serrated carbide inserts, which are also easily replaceable and, if needed, adjustable to fit barrel O.D. For more information, contact Dave Manson Precision Reamers

That has to be the coolest hand powered tool I have scene in a very long time. I can tell you honestly, if I had the money in my pocket right this minute, I would call and order one. I have friends who need this done and don't realize it. Thanks for the actual use video instead of some cheesey info- mercial.

@doug32588 @doug32588 Hello,Doug Thank you for your positive feedback. BTW, Dave Manson will soon be selling "Military Rifle Crowning Kit", which will be much less expensive because of reduced number of components. Watch my other video about this kit. Best to you, Boris

I can see the guide moving a bit left and right on the video while your cranking. I'm no Einstein, but that is not cutting absolutely square and true if I can visibly see that mandrel and guide moving side to side. A power tool would certainly help since that big handle puts too much force on that tiny guide mandrel.

This has to be one of the best tutorials I have seen! Great job Dave! Does this work with air rifles too?

[poisonforlunch]

the bore brush is a nice touch.

[AMDR3A]

where can i get one and how much is it?

[ninja6kid]

very cool

[TimeForGoodCleanFun]

aha, they DO have a polishing tool that uses the same pilot (p.14 of their catalog PDF)

[TimeForGoodCleanFun]

that's a great tool design - brilliant use of the bore brush. the cutting edges look very efficient for a hand-powered tool.

if i may suggest one addition to the kit: brass-faced tools (and/or a softer material) to slide on the pilot and polish the crown without risk of rounding the edges.

"I'm surprised that there was no chamfer where the bore breaks into the crown"

This is done on production rifles, but NEVER on extreme accuracy target rifles. the Mason crown is what you want for utmost accuracy.

I noticed the barrel threading. If you have and attachment (that you don't plan to remove) on the barrel, do you really have to worry about protecting the crown with the 11 degree crown? Thanks for the vid.

this is a great video! Please tell me where i can get one and how much!
