Product no.: 787375124

Mfr. No.: 375124CM

All the loving care of the best stockmaker and the meticulous attention to detail of the master machinist will not make a gun shoot any straighter than the accuracy capability of the barrel used. And, it is the insides of a barrel, that very small and vital area of lands and grooves over which the gunsmith has no control, that can determine whether the finished work of art is for shooting - or “just for looks”. Craftsmanship . . . not price . . . determines the quality of a barrel. But, by the same token, the customer willing to spend the money for a custom gun is shortsighted indeed, if he starts economizing and orders “just any old barrel so long as it’s cheap”. Furthermore, he is jeopardizing your reputation as a gun builder by making such a request. We, as your supplier, are laying our reputation (and yours, too!) on the line by offering you barrel blanks. They have got to be good or we are in trouble! Big trouble!! We must never sell you anything but that which will enlarge your stature with your trade. And, we feel that the Brownell Barrel, made for us by Ed Shilen, will do just that! Shilen barrels, either chrome moly or Stainless, are rifled with six lands and grooves by the “Cold Forming” process using carbide dies made in Shilen’s own plant under the most rigid controls. This rifling method achieves extremely close inside uniformity from breech to muzzle. Finished barrels are air-gauge inspected (air-gauged sensitivity is .00005" - five-one-hundred-thousandths!) and 6X borescope in- spected. All barrels, .22 through .30 caliber have groove tolerances within .0005" and uniformity within .0003" No straightening is done, and all barrels are completely stress-relieved. All stainless steel barrels are hand lapped at the factory. Only those barrels passing all spec tests are offered to the trade. Any barrel even slightly “suspect” is started through the production process again and bored to a large caliber. In no other way can quality and reputation be maintained. Slightly more expensive to produce - but vastly greater in quality and ultimate performance.

Elevate Your Craftsmanship with the Shilen Contour #4 Barrel

The Shilen Contour #4 Barrel is designed for the discerning gunsmith who values precision and quality in every aspect of their work. Available in both Chrome Moly and Stainless Steel, this barrel ensures exceptional accuracy and performance.

Product Description

All the loving care of the best stockmaker and the meticulous attention to detail of the master machinist will not make a gun shoot any straighter than the accuracy capability of the barrel used. The insides of a barrel, that very small and vital area of lands and grooves over which the gunsmith has no control, can determine whether the finished work of art is for shooting - or “just for looks”. Craftsmanship, not price, determines the quality of a barrel.

However, a customer willing to invest in a custom gun is shortsighted if they economize by ordering “just any old barrel as long as it’s cheap”. Such requests jeopardize your reputation as a gun builder. As your supplier, we stake our reputation (and yours too!) on the quality of our barrel blanks. They must be good, or we are in trouble!

We believe that the Shilen Barrel, crafted for us by Ed Shilen, will enhance your stature within the trade. Shilen barrels, whether chrome moly or stainless, are rifled with six lands and grooves using the “Cold Forming” process with carbide dies made in Shilen’s own facility under the strictest controls. This method achieves extremely close inside uniformity from breech to muzzle.

Finished barrels undergo air-gauge inspection (with sensitivity of .00005" - five-one-hundred-thousandths!) and 6X borescope inspection. All barrels, ranging from .22 through .30 caliber, maintain groove tolerances within .0005" and uniformity within .0003". No straightening is done, and every barrel is completely stress-relieved. All stainless steel barrels are hand lapped at the factory.

Only barrels passing all specification tests are offered to the trade. Any barrel deemed even slightly “suspect” is re-initiated through the production process and bored to a larger caliber. This rigorous process is essential for maintaining quality and reputation. While it may be slightly more expensive to produce, the resulting quality and ultimate performance are vastly superior.

Brownells USA 7mm-08 23/03/2017

Bought this barrel for a project rifle, Remington Model Seven. Had read other reviews about all the tooling marks that are present, they were not lying as the borescope revealed. Started to doubt my decision on buying an inexpensive but reputable barrel manufacturers product. Chambered and installed the barrel. Headed to the range with excellent results. After break-in, shot five groups of five all were under 1/2" at 100yds.

Brownells USA Perfect for hunting! 24/04/2012

I have installed over 100 rifle barrels, and have yet to see a Shilen barrel that is not up to the task set before it. For hunting rifles, these barrels outshoot factory ammo, and sub minute of angle groups with reloads is a common thing. Finish is very nice, reliability is unsurpassed. I highly recommend these affordable barrels for your next hunting rifle! You will not be disappointed!!!!
