So many variables such as barrel diameter, sight location and attachment method, barrel band locations, mag tube design, etc, make it nearly impossible to thread every model and caliber.  The manufactures have made many changes over the years and are constantly revising designs.  Please call to discuss your particular gun and have your model number available. Shortening the barrel on some lever guns is not possible due to barrel band and mag tube designs and limitations.

This is a service offer to thread your lever action barrel and make a custom thread protector.

The photos are examples of our work.

We thread your barrel to the thread pitch requested.  We shorten the mag tube to match the barrel if needed.  If the sight needs to be relocated and is held on with a screw, we can drill / tap new holes. If the sight is in a dovetail, we cannot relocate it since we do not have a way to mill a new dovetail.

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, .578x28


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 sufficent shoulder.


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

Extremely heavy or large items, such as hard cases, may require additional shipping fees. 
We ship to US states, except where prohibited by law. No sales to CA or HI.

Great comms, fast turnaround, and outstanding craftsmanship. Threads and shoulder make each of my suppressors perfectly aligned with the bore. I'll definitely be coming back for any lever rifle threading work I may need in the future, thanks!
Amazing Craftsmanship

I was slightly hesitant to have my JM Marlin 1894ss cut down and threaded since it has become somewhat of a collector's item. As a CNC machinist of 12 years, I must say I am amazed at level of detail and craftsmanship that went into my rifle. It looks better than factory and it shoot DEAD ON. Grumpys is as LEGIT as it gets. He is a TRUE gunsmith. I will be giving me business to him again in the future.

Very Happy

I sent my Rossi 92 in to Grumpy's and he did a great job!. He shortened the barrel and the mag tube, threaded to 1/2x28 and added a Marble's ramped front sight base with a .343" front sight that I sent with the rifle. Dan was quick to answer emails and quick to answer the phone when I called. Highly recommend.
Fantastic job!

I dropped my Marlin 1895 45-70 guide gun off on Tuesday and picked it up on Thursday (please note this isn’t typical, just a combination of perfect timing and dumb luck on my part). Dan did a fantastic job! I will be sending him more barrels.
