We thread your barrel to the thread pitch and barrel length requested.  Tell us which suppressor or muzzle device you have, so we can use the correct thread specs.  We have thread specs from most of the suppressor manufactures.  The process is single point threading on a commercial lathe, concentric to the bore.


Typical thread size is  1/2"x28 for 22lr & 9mm, .578x28 for 45 cal, Other thread sizes are available.

 A custom thread protector is included for all barrels.  We can knurl or leave it smooth.

Ruger Mark 3 Hunter

Long fluted hunter barrel. Excellent work, including relocating the front sight and the thread protector. Impressively fast turnaround as well. Any other threading jobs in the future... going straight to Dan!
Great to do business with

Dan with Grumpy's took his time to explain all I need to know to have my Ruger Mk2 threaded. The barrel came back perfect and ready to go. Super high quality workmanship. I would highly recommend.
Absolutely amazing work, just amazing!!

I buy a lot of suppressors, but never thought about getting a 22 suppressor until now. So I went ahead and bought my first Ruger Mark II SS Bull Barrel Target handgun. I was searching the internet to see what my options were on getting an adapter or getting it threaded. As I search I came across Grumpy’s Guns, "Best search ever." I noticed he was local, here in Texas. I called him and asked if I could come by to drop off my Ruger. Dan was very friendly and helpful and told me to bring it on by. I showed up on Thursday, talked for a little bit and told him what I wanted done. Dan looked at my handgun and told me he would probably have it ready by the beginning of next week. Sure thing, Monday morning, Dan called and said the handgun was ready. I showed up about noon. Man, I was amazed how beautiful the threading on the firearm turned out. Amazing! Even the thread protector was absolutely gorgeous and crowned. I took it home, screwed on my suppressor and it fit perfect. Dan, I can’t thank you enough for the amazing work on my handgun. Lucky to have you near by. To all that shipped your firearms to Grumpy’s, you guys picked the right man for the job. When I dropped off my gun on Thursday, he had received several guns by mail. By Monday when I picked up my Ruger all those fireman that were mailed to him on Thursday and Friday were all ready to be shipped back out to their owners too. Super fast turnaround! Thank you sir. I will definitely be back to thread the rest of my firearms.
Great Work and Great for "Unconventional" Threads

I recently ordered a Rugged Obsidian 45 suppressor mainly for my AR pistol in 45 auto/acp (5/8x24 threaded barrel). I just got my Mark III 22/45 back from Grumpy's and he was able to thread it in 5/8x24 for me and it looks great. He also moved the front sight back (I'm looking forward to zeroing it tomorrow). I bet no one will be able to figured out this was modified because the work is flawless and looks like "fresh from the factory quality work". 5/8x24 thread is not unconventional threading; however, for 22LR it is (making my Mark III unique). Doing a special thread (5/8x24 instead of standard 1/2x28 for 22LR) saves me the cost of buying the 1/2x28 adapter. Furthermore, it makes it easier to swap my future suppressor from the two guns I plan to use my future suppressor on the most. Finally, I indicated that I was not in any rush to get this done in my comments section on my order, yet his turn around time was very fast. This indicates that he has a great work ethic and turn around is only limited by how busy he is. I will highly recommend him when anyone needs a barrel threaded.
Amazing work at a fantastic price

Dan with Grumpy's Guns is an amazing Gunsmith with fantastic prices and quality workmanship. I recently utilized his services for the first time on a Ruger 22/45 MKIII for barrel threading and the quality on the work is just fantastic. The thread protector comes on and off flawlessly. Using the laser micrometer at work shows that concentricity is perfect (10,000th of an inch). The process for start to finish was easy and fast. I shipped him the barrel that arrived to him by Wednesday and within a week I had the barrel and action in my hands. With this experience I will definitely be using his services again and I encourage others to do the same.
