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.

I don’t normally leave reviews ,but this was so perfect and fast I was impressed .he Threaded the barrel on my 45colt Henry Big Boy Color Case Hardened Carbine ,Looks like it was made that way
Incredible craftsmanship, lightning fast turnaround

I sent Grumpy's my Henry Big Boy .357 lever action rifle to have the barrel threaded. The attention to detail on the threads is incredible and the provided thread protector looks like it originally came on the rifle. He also had to shave down the front post sight slightly to accept the threads and you'd never know this wasn't a factory job. You won't be disappointed.
Very Impressed

I sent my Henry 45-70 out for Grumpy's barrel threading service and I am extremely impressed. The threads align perfectly with my suppressor, the thread protector looks like it was factory made with the gun. I will definitely be sending my next Henry rifle out to Grumpy's when I get it. I cannot recommend this service enough. I got my rifle back in less than two weeks!
A great find and superb service

The customer service at Grumpy Guns is above and beyond. When I first contacted Dan, he fully explained the options and what was necessary to have the barrel of my Henry H001 22 threaded. I shipped the rifle to him and within what seemed to be a couple of days I received notification that I was receiving a package from Grumpy Guns. The work was excellent. I sent him a brand-new rifle fresh out the box and he returned it the way he received it. The thread protector appeared to have been made when the rifle was manufactured, and the tolerances were perfect. I was so impressed with Dans work that I sent him another Henry H001 which he returned with the same high-quality work. I’m already getting things ready to send him a Rossi Stainless Steel which I’m sure will look amazing.
