What are your opinions on prefit barrels?

Whether or not the action is in hand does not predict the quality of the chamber. I dont need any of the good customs in hand to chamber the barrel and its as good as if I do. The tight thread fit that used to be popular is not desirable to me for accuracy. Its about the time taken to indicate the bore and get a good setup.
 
Here is a review I just posted on Urbanrifleman's Pre fit on a Rem 700:

Groups were very impressive:

Review: urbanrifleman's 6 BRA 8T minimal freebore SS Barrel

About a month ago, I took delivery of one of Urbanrifleman's 6 BRA zero freebore SS 26" Remage barrels. Since I chamber my own barrels, I was very interested in the quality of: A. barrel quality in general B. Machine work Needless to say, I was very, very impressed with both. First, the...

Im thinking to get new brass for a off the shelf barrel prefit would be fine and you might get a really good shooter. You know chamber specs are gonna be different.

Every year I call Brian at Plainfield Precession and tell him I need another barrel for the rifles he built for me 4 yrs ago. He spins em up and mails em to me.

Same action, Same chamber specs ...... As best as can be done ....
Last year I didn't buy new brass (6mm) and it shot better than the year before.

If you get an "off the shelf" barrel, that's someone else's idea of what's right for you.
Get it "the way you want it".
Custom cut chambers cut to YOUR SPECS will make it YOURS!!
Most everybody has their own idea of what works best. What works for me may not work for you. ;)
 
I have a Savage "target" action with a Criterion pre-fit in 243 Win, that shoots better than I am capable of. However, if I were to build a new rifle on a custom action I would not use a pre-fit. That would be kind of like buying a Porsche and putting Cooper tires on it - not that Cooper tires are bad, they just don't offer the performance the car is capable of.

I don't know that it is true, but I have read several times that Criterion will use your reamer to chamber a barrel.

IMO the "ACE" introduces more issues than it offers solutions to. As others have already said, you have a huge potential for alignment issues. Also, you are introducing another joint in the chamber/barrel system, right at the end of the chamber. The other thing I find intriguing is their narrative about "not being held hostage" to a precision gunsmith, but yet the last line in their ad says that only Wolf Precision is capable of threading a barrel for their system. So with the ACE, when needing to change barrels, instead of having 100's of gunsmiths to choose from, you only have them - "held hostage"?

I do applaud them for thinking outside the box, but I think the ACE is a solution looking for a problem.
 
Some people think the nut has something to do with the quality. It is just silly... SILLY.

Straight chambers and good quality barrels shoot. The nut has nothing to do with it.... except setting the headspace. These propaganda ideas that prefits are "sloppy", or are less than quality are total BS. Anyone who has done any machining will be speaking falsely if they say that a prefit is machined "sloppy". It is total BS.

Threads are cut to spec, threads cut straight, chambers are cut straight (some more straight than others), nuts are machined straight...

This is prefit. Think it won't shoot???


It is just another form of SNOBBERY to badmouth prefits. That is all it has ever been. All it will ever be. Good is good, and junk is junk. Lots of JUNK BARRELS that shot like crap had shoulders and were "fit" by a gunsmith.

Who is saying they won't shoot, or that they're sloppy?
 
Not sure I understand the concept here. When I went to that site, what I think I saw and read indicated, at least in my mind, was an extension of the action that was the actual chamber not a prefit barrel.

It may or may not be the best thing since sliced bread.

We all know that when a rifle starts to shoot erratically, most times it is caused by normal wear and tear of the chamber. Done properly I see no reason that it can't work, although I certainly am no expert.

My problem with this is, they guarantee it for life. Does this include fire cracking? Notice, they state you should never have a barrel threaded by any other source but them. Why? Are they saying that no one else has the ability to duplicate their process?

Reminds me of the ad by Mr. Pillow!!!!!!

A lot of people on this board. For years and years. It is not controversial to say that. Many have had to crawfish in recent years and admit that prefits can shoot (or at least stop bashing them), but I very clearly remember a time when bashing anyone with a nut barrel was the standard on this forum.
 
The only difference in a fitted shoulder barrel and a nut barrel in my shop, is that you can clock a shouldered barrel to the action for any curve in the barrel.

Other than that... not a jot of performance difference... specs are the same.
