Tear down and re-assemble your upper $40
All barrel machine work requires the barrel to be removed from the upper receiver. If you are not outfitted to do this yourself, we can handle it for you. If you only have 1 or 2 rifles, it's probably not worth buying the tools. If you have several rifles and you feel you are mechanically inclined, I would encourage you to get the barrel wrench, torque wrench, pin punches etc and do it yourself.
 
Barrel Threading $30
This is the most commonly requested service. The barrel gets mounted in the lathe with a live center in the muzzle. The muzzle gets turned down to the required size and then threads are cut with a single point tool. This ensures that the threads will be perfectly concentric and parallel to the bore. After the threads are done and deburred, a new crown is cut to eliminate the damage caused by the live center. I can turn any of the common thread sizes such as 1/2-28, 9/16-24 or 5/8-24 with verification from my gauges and tooling. The threaded area will be left unfinished. Picture
 
Barrel Threading on lightweight barrels $40
This is done like normal barrel threading with a couple exceptions. Lightweight barrels will usually measure about 0.6" at the muzzle. When I turn that down to 1/2" for 1/2-28 threads, it only leaves a 0.05" shoulder. This is too small to properly torque a muzzle device against as most flash hiders have a generous chamfer at the entry of their threads, this chamfer ends up right against the square corner of the lightweight barrel's shoulder and it's not a good situation. This service includes threading the muzzle an extra 3/8" back and making a threaded tapered bushing that will seat against the small barrel shoulder and provide a more proper shoulder to tighten against. The bushing will be finished with touchup bluing and the threads are generally left unfinished. Picture Picture 2 Picture 3
 
Precision Barrel Threading $50
This is a more specialized threading service required when the typical threading above will not handle the job. This is also required when you have a permanently attached muzzle device that we will remove before threading or fixing the existing threaded area. The barrel gets mounted in the lathe with a live center in the muzzle. The muzzle gets turned down to the required size and then threads are cut with a single point tool. This ensures that the threads will be perfectly concentric and parallel to the bore. After the threads are done and deburred, a new crown is cut to eliminate the damage caused by the live center. I can turn any of the common thread sizes such as 1/2-28, 9/16-24 or 5/8-24 to a specified pitch diameter. If you are mounting a sound suppressor, the manufacturer will usually specify a pitch diameter or mating thread class fit. I can also turn any other thread size you could ever need as long as I have a mating part or a similarly threaded part to measure. This includes 1/2-36 as used on 9mm, any of the 28 TPI sizes like 9/16-28 or 3/4-28 etc. The threaded area will be left unfinished.
 
Gas Port Work $25
Gas operated semi-automatic rifles need a specific amount of gas tapped from the barrel to operate the action properly. All kinds of problems are caused when the gas port is not right to include failure to feed, extract, eject etc... Anytime a barrel is shortened radically, it will need the gas port opened up for proper function. This service includes pulling off the front sight base and opening up the gas port to proper size according to our extensive list of barrel configurations and known gas port sizes. If your gas port has already been opened up too far, we can also install a bushing to bring it back down where it belongs. Gas port work does not require the barrel to be removed from the upper receiver.
 
Gas Port Work with Test Firing $50
Gas operated semi-automatic rifles need a specific amount of gas tapped from the barrel to operate the action properly. All kinds of problems are caused when the gas port is not right to include failure to feed, extract, eject etc... Anytime a barrel is shortened radically, it will need the gas port opened up for proper function. If your gas port has been opened up too far, we can also install a bushing to bring it back down where it belongs. This service includes pulling off the front sight base and opening up the gas port to proper size as determined by test firing with specific ammunition to be provided by the customer. We will open up the port to the minimum size required in small steps while test firing for proper function on your upper. This helps to eliminate excessive wear on the internal action parts. Gas port work does not require the barrel to be removed from the upper receiver.
 
Relocate Gas Port $75
Gas operated semi-automatic rifles need a specific amount of gas tapped from the barrel to operate the action properly. All kinds of problems are caused when the gas port is not right to include failure to feed, extract, eject etc... Anytime a barrel is shortened radically, it will need the gas port opened up for proper function. If your gas port has been opened up too far, we can also install a bushing to bring it back down where it belongs. This service includes profiling the back half of the barrel as required to mount a new gas block, drilling a new gas port and closing up the old gas port. You will likely also need a low-profile gas block to hide under the handguards. This is the proper fix for 16" 'dissipater' setups made from 20" barrels or 300x221 barrels that do not function because they have a carbine located port. We open up the gas port to proper size as determined by test firing with specific ammunition. We open up the port to the minimum size required in small steps while test firing for proper function on your upper. This helps to eliminate excessive wear on the internal action parts.
 
Shorten Barrel and Thread Muzzle $40
This service includes shortening the barrel to any length you specify and normal threading to 1/2-28, 9/16-24 or 5/8-24 and re-cutting the crown. Machined areas will be left unfinished. Picture Picture 2 Picture3
 
Shorten and Thread Muzzle on lightweight barrels $50
This service includes shortening a lightweight barrel to any length you specify, threading to 1/2-28 and re-cutting the crown. Lightweight barrels will usually measure about 0.6" at the muzzle. When I turn that down to 1/2" for 1/2-28 threads, it only leaves a 0.05" shoulder. This is too small to properly torque a muzzle device against as most flash hiders have a generous chamfer at the entry of their threads, this chamfer ends up right against the square corner of the lightweight barrel's shoulder and it's not a good situation. This service includes threading the muzzle an extra 3/8" back and making a threaded tapered bushing that will seat against the small barrel shoulder and provide a more proper shoulder to tighten against. The bushing will be finished with touchup bluing and the threads are generally left unfinished.
 
Remove Permanently Attached Muzzle Device $20
This service includes machining away your old muzzle device and cleaning up the threads to prep the muzzle for a new muzzle device to be permanently attached. In most cases, the old muzzle device will be destroyed so it will not be salvageable.
 
Permanently Attach Muzzle Device $20
This service includes drilling through the installed muzzle device and into the barrel, installing a blind pin, welding over the end of the pin and machining the surface of the weld to match the profile of the muzzle device. This does not include barrel threading. This service is required to convert a 14.5" M4 barrel into a legal 16"+ barrel length. Machined areas will be finished with touchup blue where applicable. Picture
 
Shorten and Crown $25
This service includes shortening the barrel to any length you specify and re-cutting the crown as described below. Barrels that have been radically shortened will also require gas port work priced elsewhere. The crown face will be left unfinished after the cut is made. I can add touchup bluing upon request.
 
Crown Job $15
Many poor shooting barrels can be traced to problems with the crown. The crown needs to be absolutely perpendicular to the bore. When the bullet leaves the bore, gas is released at very high pressure all the way around the bullet's base. If the crown were uneven, gas would release on one side first and this tends to disturb the bullet just as it sent on it's way downrange. Obviously this will show up as poor accuracy. Try this inexpensive service before you abandon a barrel that seems to be poor shooting. I use a specially ground high relief angle tool that only gets used for crowns and it gets re-sharpened before every job. The tool is pulled straight out from the bore so that no burrs are created at the end of the bore. The bore-crown junction will be flat, with a radius about half way out on the crown face. This creates a slightly recessed crown job. The crown face will be left unfinished after the cut is made. I can add touchup bluing upon request. Picture
 
Compensator Indexing $10
The typical method to index a compensator to the barrel involves the use of peel washers or crush washers. Neither method leaves a nicely finished look. This service is purely cosmetic, but it's one of those small details that you come to appreciate on custom rifles. I can index a muzzle device to your existing barrel by facing off the rear of the muzzle device, or by facing off the barrel torque shoulder if the barrel will already be in the lathe for other operations. Simple facing of the muzzle device does not require the barrel to be removed from the upper. I will add touchup bluing where appropriate.
 
Compensator Re-Threading & Re-Boring $10
Typical Flash hiders are threaded 1/2-28 internally. 1/2-28 threads are not appropriate on barrels larger than 6mm I typically recommend 9/16-24 or 5/8-24 for barrels with larger bores Typical military flash hiders have two grooves on the outside that only allow them to be opened up to 9/16-24 The minor diameter at the bottom of the grooves is 5/8" and opening them to 5/8-24 causes them to break in half. Aftermarket compensators come in many different sizes and many can be re-bored and re-threaded to work on larger calibers. Internal threads will be left unfinished.
 
Partial Barrel Profiling $50
This service is to turn your heavy barrel down to any lighter profile you specify. This includes the diameter under the handguards or the diameter from the front sight base forward. I can turn any kind of profile that includes basic straight cylinders and short tapers not to exceed about 2" in length. This service does not provide for changing the gas block seat diameter. This service can be combined with basic threading to turn a heavy 'post ban' barrel into a medium weight 'no-ban' barrel without the need for a tapered bushing to support the muzzle device. Machined areas will be left unfinished.

Full Barrel Profiling $75
This service is to turn your heavy barrel down to any lighter profile you specify. This includes the diameter under the handguards and the diameter from the front sight base forward. I can turn any kind of profile that includes basic straight cylinders and short tapers not to exceed about 2" in length. This service also provides for changing the gas block seat diameter from 0.940" down to 0.750". This service can be combined with basic threading to turn a heavy 'post ban' barrel into a lightweight 'no-ban' barrel without the need for a tapered bushing to support the muzzle device. Machined areas will be left unfinished. Picture
 
Blast and Parkerize $35
Any profiling work that is visible will generally require the barrel to be blasted and parkerized. This also fixes barrels that were parkerized with the front sight base assembled instead of separately. Barrel threading and crowning can generally be touched up with simple touchup bluing, but the finish does not match parkerizing. If your barrel has a few scratches and you just want it to look new again, this is what you need. Picture Picture 2
 
Full HBAR package $120
De-HBAR your HBAR. This is almost everything you can do short of replacing the barrel. We will fully profile to any profile you specify, shorten, thread the muzzle for standard muzzle devices, permanently attach your muzzle device if required, blast and parkerize the barrel.
