These barrels are a true match-grade barrel, we only have one grade for all of our barrels, our best. All of these barrels are made from 1.25″ diameter 416 alloy rifle-barrel-quality stainless steel. Every barrel is drilled, reamed and rifled in our shop followed by a stress relieving heat treatment operation. They are then hand- lapped for a superior internal finish and diameter uniformity.

I only have 1 profile available for this barrel.
These barrels are made with a new ‘Lilja 3’ chamber made by Manson Reamers. With these drop-in barrels we then turn the shank end of the barrel to the proper dimensions and cut a match chamber. This chamber does allow slight engraving of the bullet in the rifling. Extraction of unfired ammo is not guaranteed with this chamber.
The barrel is then cut to final length and crowned with an 11 degree target-type crown. Each barrel is then polished to a 600 grit exterior finish and then our name and the cartridge designation is engraved on the barrel. And lastly the finished barrel receives a final inspection and is sealed in a 6 mil poly tube and placed on the shelf.
One of our CNC lathes that does the turning work on the chamber end of the barrel and cuts the chamber.
Drop-in barrels do not require any special gunsmithing. Directions for installing the barrel are furnished with each barrel. These instructions can also be found directly below. If you do not feel qualified to install your new drop-in barrel we can do so for a $50 charge.
Here is a link to our Facebook page with a video helping explain the process of measuring your headspace. headspace. https://www.facebook.com/580697272005364/videos/338760933509372/
Installation Instructions
First you will need to measure your headspace. The most accurate way to do this is by using a depth gauge, and measuring from the receiver face, to the bolt face recess while the action is cocked. Let’s say you get a measurement of 1.235” and you want your headspace at .043”. That means you need a shank length of 1.192”.
(1.235 – .043 = 1.192)
Every barrel will have a shank length of 1.200”. So now we know to shim the barrel .008” to obtain proper headspace.
(1.200 – 1.192 = .008)
Now that we know how much we need to shim the barrel, we can use a .005” shim and a .003” shim stacked together to obtain headspace. You can use any combination you’d like, but try to use the least amount possible.
Slide the .005” and .003” shim onto the barrel shank, making sure they are fit up tight against the shoulder of the barrel.
Slide the new barrel, with shims up firmly against the shoulder into the new action, being careful to align the ridge of the cuts for the set screws at the 6:00 position. Tighten the two set screws equally, pulling the barrel into the receiver. Recommended Torque is 35-40 Inch Pounds.
The receiver stock screws are a T-27 Torx Head
Note: We turn the barrel shanks slightly larger than the original CZ dimensions on this diameter. We’ve seen a couple of receivers that had a slight burr where the angled tapped holes break out into the receiver bore. This little burr prevented the barrel from sliding into the receiver with our close fit shank. So if you find the barrel difficult to slide in place initially, check for these burrs.
We offer a .043” Go Gauge made by Pacific Tool and Gauge. Please note that it is not necessary to use a Go Gauge to get correct headspace using this method.
