Barrel Threading Service for Rifles

Price: $99.00
Item Number: RBRL


Rifle Barrel Threading Service


This a service offer to thread your barrel.
No parts are included in this service.

The photos are examples of our work. No barrels are included in this service.

We thread your barrel to the thread pitch requested.

The threading process is single point threading on a commercial lathe, concentric to the bore

Typical thread sizes are  1/2"x28, 5/8"x24, .578"x28, etc...

The shoulder behind the threads is what a suppressor or other muzzle device aligns itself against.
There needs to be a minimum of .100" barrel diameter increase over the major diameter of the threads for a sufficient shoulder.  This is a non-issue for heavy varmint and bull barrels, since they are already larger in diameter.


  • 1/2-28 = .600" Shoulder Dia.
  • 9/16-24 = .6625" Shoulder Dia.
  • 5/8-24 = .725" Shoulder Dia.
  • 3/4-24 = .850" Shoulder Dia.

 A custom thread protector is included.

Send us just your barrel if possible. We will accept barreled actions, and complete guns. If you send us a barreled action or complete gun, there is a additional charge to remove and re-install the barrel.

We are an FFL w/ SOT (CLASS 3) dealer, so you can ship us any type of firearm and/or muzzle device. 

No AK-47, SKS or Mosin Nagant.

Free shipping is no longer possible without raising our prices, because UPS, FedEx and USPS keep raising their rates.
  Our shipping fees have more than doubled in the past year.

Complete guns or extremely heavy or large items, may require additional shipping fees.
e ship to US states, except where prohibited by law.


Please include a note in the shipping box, with your name, return shipping address, barrel length, and description of work needed. Write the serial number of the gun on your note or receipt.

Turnaround time varies based on current workload, but will usually be finished and shipped  within 14 business days from the day we receive your barrel. If you would like to confirm the current turnaround time, please feel free to contact us prior to your purchase.

Received a call from Grumpy's, my shipping container (bought at fed ex - tube) was torn apart, my barrel intact, no scratches. Verified work to be completed, received a trk# the next day of barrel completed and shipped. These guys are the real deal, fast turn around time...less than 2 wks! Absolutely awesome, thank you.
Outstanding Service!

I sent my barreled action in to have the barrel threaded. I did not pad the action as good as i should have for shipping (my fault)and the trigger was broken when it arrived at Grumpys. Mr. Dan emailed me about the problem. He was able to find a replacement trigger group and repair the problem an STILL managed to thread the barrel and get it back to me in a about 2 weeks! I can not say enough good things about Grumpys. I would not hesitate to use them again! Great service and a job well done. Thank you Mr. Dan.
Best service by far

If I could rate higher than 5 I would. First rate service, was quoted for a certain turnaround time and was completed and delivered faster than expected. Not sure why he’s called grumpy because mr.Mulder is a super stand up guy and super knowledgeable to boot. I hope he took a liking to me because I plan on sending lots of projects his way. Thanks for the awesome work grumpy, I’ll definitely be using your service again soon.
Great work at a fair price

Dan did really great work on threading 3 different barrels for me so far. The turnaround time was quicker than what I expected and faster than originally estimated. I was very pleased with the quality and was very satisfied. Especially with how quickly he sent me back the Marlin 70P barrel. I was blown away how quickly I got that back, and it looks great! I would highly recommend Grumpy's services and I will at some point be getting more threading done and Dan is the man that I will be contacting to do the work. It will be done right, it will be reasonably-priced, and the turnaround time will be excellent. Give Grumpy's a try, you'll be glad you did!
More Barrels Headed Your Way

Elated to deal with someone who does things right the first time. Unbelievably quick turnaround and quality of work is second to none. Entire process was smooth and without any problems whatsoever. After seeing the great threading job on my Buckmark barrel, getting ready to ship my Lilja 22LR barrel for my CZ 455 and that will be followed by HMR 17 and 22 Mag barrels. Dan responded quickly to my email regarding the threading of a Beretta 92 barrel. That kind of customer service is all too rare these days where businesses often won’t bother to respond. Very reasonable price for quality work. Semper Fi
