Great Investment

Purchased this tool to make a new crown on a used barrel I shortened to 24" in order to restore the rifling on a damaged tip. The tools performed perfectly. Much better than cheaper tools using a brass arbor. I do a bit of gunsmithing and I'm sure this tool will perform well on new barrel blanks as well. Worth every penny, I'll have to buy a few more arbors as needed.

Best crowning tool

Does the job done

Manson Precision Crowning Kit

As a law enforcement armorer I needed/wanted to cut down four (4) precision rifle barrels to 18". The cost of the two (2) arbor kit was close to the cost of having the work done. Once the kit arrived it was very easy to setup and use and it did a very fine job. Best of all a guy can hacksaw cut a precision rifle barrel and finish off the cut with this tool. A straight cut of course makes the finish job much faster. I have owned this kit for three years plus now and have cut down at least 20 barrels and have loaned it out to other agency's. It still cuts as well as it did on day one. The average time from start of cut to finish is about 30 minutes....taking your time. This is a very high quality tool and does a professional crowning job with ease. While the initial cost seems high it is well worth the cost and can pay for itself many times over.

What a time saver !!!!!!!!! WOW !

I use to use my south bend lathe and a 4 jaw chuck. and had to take the gun apart to do it. charged 1 hour labor and always took me two. With this it is done in 5 minuets!! WORTH the money !! Will be buying more adapters asap to do more.

Excellent kit for the money

Used the first time today to recrown a Mosin Nagant that I believe saw action due to the muzzle being so beat up. The set is very easy to use, remember to use cutting oil (as it states in the instructions) and it makes crowning a muzzle really easy.

Excellent kit!

So far I've used this kit to cut and re-crown three rifles, all with excellent results. I just got done cutting an inch off of my .308 Rem 700 varmint, and at the range today I shot a five shot group of .309. Even with the bedded stock and carefully hand loaded ammo, this wasn't possible before the cut/re-crown. I've also cut and re-crowned several Mosin Nagants which dramatically improves the accuracy of these rifles. I can hold under one MOA in the last Mosin I worked on. Previously, I thought you needed a high-end lathe and heaps of experience to achieve this. Not.

Excellent Tool

Since I received this I have done 3 10/22 crown jobs and the results were perfect. This is a very easy gizmo to use, dare I say foolproof. A quick touch-up with Brownell's Oxpho-Blue and I would dare to suspect my 10/22 has a better than factory muzzle now.

The perfect solution to recrown a barrel

I just purchased this kit a couple weeks ago, all i can say is Wow, this recrowning kit is simple to use and does an amazing job! I have been playing with a couple .22 rimfires and they went from ok to tack drivers after recrowning the barrels,one of the best purchases I've made.

You get what you pay for. This is a well-made tool that is very easy to use. The resulting crown is clean and sharp looking.

Worth the money

I bought a cheaper crowning tool to reface and crown .223 barrels. After barrel #8, the pilot tube broke off the face of the cutting tool. Rather than spend another $90.00 to replace a tool that already failed, I bought the Manson Precision refacing kit. I first watched a demo of the tool on You Tube. When I used it the first time, it worked exactly as demonstrated. Made smooth cuts with no chatter marks. The pilot bushing fits well inside the barrel. The brush on the end helps remove chips from the barrel as the bushing is pulled from the barrel. The hand crank and guide work very well to provide steady and even downward pressure to the cutting blades. It cost more but the quality and ability to do .22 and .30 calibers made it worth the money for me. If you plan on refacing many barrels this is the professional grade tool to use.
