Tear down and re-assemble your upper $50
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.
 
Assemble an upper $30
This service is to assemble an upper from a box of parts. If you are only building 1 or 2 uppers, it's probably not worth buying the tools. This service includes checking headspace and all of the same reliability checks I perform with the tear-down and rebuild service above.
 
Standard Barrel Threading $40
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. Other shops would consider this a 'precision' threading job. I do the standard thread sizes, 1/2-28 or 5/8-24, with verification from my gauges and tooling. Other sizes will require the precision threading service below. The threaded area will be left unfinished. Picture
 
Precision Barrel Threading $60
This is a more specialized threading service required when the typical threading above will not handle the job. 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, 9/16-24 or any of the 28 TPI sizes like 9/16-28 or 3/4-28 etc. The threaded area will be left unfinished.
 
Shorten Barrel and Thread Muzzle $60
This service includes shortening the barrel to any length you specify and normal threading to 1/2-28 or 5/8-24 and re-cutting the crown. Machined areas will be left unfinished. Opening up the gas port for proper function at your new barrel length is also included. Picture Picture 2 Picture3
 
Shorten Barrel and Precision Thread Muzzle $80
This service includes shortening the barrel to any length you specify and a more specialized threading service required when the typical shorten and threading service above will not handle the job. The barrel gets cut to length and then 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 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, 9/16-24 or any of the 28 TPI sizes like 9/16-28 or 3/4-28 etc. The threaded area will be left unfinished.Opening up the gas port for proper function at your new barrel length is also included.
 
Shorten and Crown $30
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 finished with touchup bluing where applicable.
 
Crown Job $20
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 finished with touchup bluing where applicable. Picture
 
Gas Port Work
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.
Open up gas port$25
Plug oversized gas port and re-drill to correct size$75

Detent barrel $10
This service is to fixture your barrel in the mill and then drill a detent for a setscrew-attached gas block. The dimple ensures that the gas block is located properly to align with the gas port on the barrel. The dimple also ensures that the gas block will not slide forward under recoil. Any gas block being used with a gas piston operating system should be cross pinned to the barrel using one of the services below. Picture
 
Single Cross Pin Gas Block to barrel $20
This service is to fixture your barrel and gas block in the mill and then cross drill and ream for a 1/8" diameter dowel pin.
 
Pin Virgin Front Sight Base to barrel $40
This service is to fixture your barrel and FSB in the mill and then drill and ream for standard 2/0 taper pins. The barrel and FSB must be new parts (un drilled) to use this service. If you are re-using a FSB or barrel that has been previously drilled before, the next service down is what you need. Please include taper pins with your FSB. We can also drill for and provide straight dowel pins if you specify in the comments area of the service form. Picture
 
Re-work Used front sight base or used barrel $60
This service is to fixture your used barrel or used FSB in the mill, locate the center of the old holes and then drill and ream the mated barrel and FSB for standard 2/0 taper pins. The barrel and/or FSB can be previously used with this service. Please include taper pins with your FSB. If the existing holes do not allow for standard taper pins to be used, we will substitute oversized pins. Picture
 
Add M4 feedramps $20
This service is to machine M4 feedramps into a barrel or complete upper that does not already have them. M4 feedramps increase the reliaility of barrels with short gas systems that run the bolt carrier at higher velocity than the original 20" barreled AR-15 design. The feedramps will be left unfinished.
 
Remove Permanently Attached Muzzle Device $30
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
This service includes drilling through the installed muzzle device and into the barrel, installing a blind pin, welding over the end of the pin. This does not include barrel threading. This service is required to convert a 14.5" M4 barrel into a legal 16"+ barrel length. Welds will be finished with oil to protect from rust. Be sure you include your barrel nut and gas block with the barrel as it is usually not possibe to install them after the muzzle device is perm attached. In some cases, the upper must be fully assembled before the perm attach job if the handguard can not be installed over the muzzle device. If you have questions about this, please ask ahead of time!

Permanently Attach Carbon Steel or Stainless Muzzle Device$40
Permanently Attach Titanium, Aluminum, Inconel or Monel Muzzle Device$60

Compensator Indexing $20
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.
 
Compensator Re-Threading & Re-Boring $30
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.
 
Receiver Facing $20
This service is to setup an AR receiver in the lathe and re-cut the front face perfectly square. It is not uncommon to see the receiver face 0.001" or more out-of-square. This service ensures that the barrel will seat square to the receiver's centerline. The machined end of the receiver will be left unfinished. Picture Picture2
 
Partial Barrel Profiling $30
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 $60
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 $40
Any visible profiling work on chromoly barrels 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
 
Glass Bead or Sand Blasting $25
This service mostly applies to stainless steel barrels. As machined, stainless barrels are shiny silver. After glass bead blasting, they will be a nice matte gray. We use glass beads by default on stainless barrels, but we can also use aluminum oxide sand which is a rougher blast more appropriate for painting. Sandblasting leaves a darker finish than bead blasting. Specify sandblasting in the comments section of the service form if you would like the barrel blasted with sand instead of glass beads.
