Don’t pay an expensive gunsmith for a barrel threading job that you can easily do yourself. Our muzzle threading kit comes with all the tools you need to thread your barrel like a professional.
Our barrel threading kit includes: 1) die stock, 2) die (your choice of size), die pilot (your choice of caliber). The die pilot helps you avoid costly mistakes by making sure you thread the barrel straight with the bore.
Save the cash you would have paid to a gunsmith, and treat yourself to another day at the range!

IMPORTANT – MAKE SURE TO USE THE CUTTING OIL THAT WAS INLCUDED IN THIS KIT. APPLY OIL TO THE CUTTING TEETH OF THE DIE. THIS HELPS TO AVOID DAMAGE TO THE DIE AND TO KEEP THE TEETH SHARP.
Watch the instructional video on GunToolRentals.com on how to properly set up the Threading Kit. The video can be found on the Threading Kit’s product description page under the tab ‘Directions.’ http://guntoolrentals.com/shop/barrel-threading/muzzle-threading-kit/
The Threading Kit contains a THREADING PILOT TOOL (TPT) that is designed specifically to facilitate the creation of threads on the outside of rifle muzzles that are both concentric and perpendicular to the rifled bore.
Your TPT package contains four parts:
1. Threaded Pilot Tool (TPT)
2. Threading Die
3. Die Handle
4. Tap & Die Cutting Oil
Warning: Instructions are for right-hand threading.
The TPT is simple to use. Even for the inexperienced, the entire procedure should not take more than five to ten minutes. For your safety, follow these directions carefully:
1. Open the action on the rifle and be sure there is no ammunition in the magazine or the bore.
2. The threading die is split along one side and has screw to adjust the die cut for shallow or deep threads. Open up the die to cut shallow threads in order to start the initial threads on the rifle muzzle.
3. Install the threading die into the die handle, with the lettering on the die facing up. Insert the die into the handle and tighten the retaining screws so that the die is held securely in the handle. DO NOT over torque the screws – you’ll strip the threads in the die stock. Just snug them up.
4. Locate the threaded bore pilot (TPT) and insert the pilot into the threaded die so that the pilot, or the unthreaded end, goes into the die from the side opposite the large chamfer. BE CAREFUL to not cross thread the pilot by forcing it into the die. Go slowly and make sure the pilot is screwing in correctly. The pilot will thread in easily when the die is adjusted correctly. Turn the threaded bore pilot threads two full turns into the die.
5. If you have assembled the TPT properly as described above, the die now has about three turns available on the chamfer side of the die to cut threads. The TPT is now ready to use.
6. Hold the barrel of your rifle firmly during the threading procedure. A good bench vice with padded jaws is desirable to hold the barrel. You can use soft wood blocks, sheet lead, or copper sheet as padding for the vice jaws.
7. Place some tape around the barrel or make a mark ~3/4 of an inch from the top (~5/8″ for the brake and ~1/8″ to 3/16″ for the jam nut. You will cut your threads down to this mark. You can always cut more threads if you need, but you can’t take those cuts back.
8. Lubricate both the pilot and die inside of the muzzle with oil. Now insert the lubed pilot into the bore of the muzzle until the die contacts the muzzle. Grasp die handles in both hands and, using some pressure, rotate the handles in a clockwise direction. You will feel the die start to cut. Keep turning the handles slowly. It is best to rotate the die handle a quarter to half turn, back off the die, then continue with another quarter to half turn. Once you have about 5 threads cut, you should be able to continue without the pilot. Remove the pilot and continue cutting the threads. IMPORTANT, WHEN USING THE PILOT, MAKE SURE TO STOP IF THE PILOT BOTTOMS OUT ON THE TOP OF THE MUZZLE – YOU WILL STRIP THE THREADS IF YOU TRY TO CONTINUE. To continue, adjust the pilot further out of the die to give you more room to cut, or, if enough threads are already cut, continue cutting the threads without the pilot.
9. WARNING: When you encounter any resistance, STOP! Do not go any further, remove the TPT, then continue threading. With proper threading, the TPT can last for years. Damaged die can be replaced at the regular price.
10. Continue cutting your threads down to your stop mark.
11. Now turn the die handles counter-clockwise and remove the die from the rifle muzzle. At this point, you have established the muzzle threads and all you have to do now is deepen the threads so the muzzle brake will screw on. The pilot is not necessary.
12. Remove the threading die from the handle and readjust the die a small amount so that the die will cut slightly deeper threads. To do this, back off the small adjusting screw in the die. Install the die back in the handle. Orient the die so that the side with the chamfer again faces the muzzle. Carefully start the die back on the established threads by turning the die handles clockwise. Continue turning the handles until your reach your stop point. Unscrew the die.
13. Try to turn the muzzle brake onto the threads that you cut. If the brake will not start onto the treads, repeat Step # 10 above and try again. You want a good tight fit on the threads with some resistance. You may have to repeat the procedure several times.
14. STOP when you are able to turn the brake on the muzzle at least four or five turns with resistance. Remove the brake from the muzzle. Now take the die that is still installed in the handles and turn the die over. The side with the chamfer should be facing you now. Again, carefully start the die onto the established muzzle threads and turn the die handles clockwise until the die reaches the stop mark. Unscrew the die from the muzzle. You are now done threading. Clean any thread cutting from the muzzle threads with a soft wire brush and install the muzzle brake. Tighten securely. If you purchased a jam nut with your muzzle brake, thread the jam nut on first, followed by the muzzle brake, and tighten the jam nut against the muzzle brake. Make sure your muzzle brake is positioned correctly.
You are now done. Please make sure to clean the tools, repackage them properly, and return them promptly.
