We do not recommend Re-Chambering 357 Threaded Barrel Blanks for a different round, for instance, changing 380 auto to 38sp.

Button-rifled! Made for people who would like to restore accuracy to older guns due to rusted, pitted or just worn out barrels. To install, first drill out existing rifling with a drill a little larger than the liner you are installing. For best results, we would recommend grinding or having someone grind a pilot on the drill about the size of the current rifling because this will keep it centered better , then solder the Barrel Liner in place. Or you can also use JB Weld or Acraglas gel because we have had many customers say they worked well.

Because we are not gunsmiths, these are just suggestions based on what we have learned over the years and from the nice people that we have come in contact with. A skilled gunsmith with proper tools should be able to install these with no problem.

357 Threaded Barrel Blanks are specifically for custom builds.

Chambered end Threaded 9/16-18 NF, Muzzle end is Threaded 1/2-28 UNEF  as a result it is easy to thread into a barrel block or frame.  In addition the muzzle end is threaded to attach a thread protector, muzzle break, Compensator or a  Flash Hider.

WARNING: Our Gun barrel liners are made and tested for the rounds they are chambered for.  Only use with the specified rounds. It is dangerous to chamber these gun barrel liners in other calibers and can cause serious bodily injury.

    Not only was the product exactly what I’d wanted, but the staff was extremely helpful on multiple occasions!
    I’d contacted them because their site had said they’d been out of stock of the .357 barrel blanks since I first looked for them in October. A guy got back w/ me, we talked a bit, & at 1 point I’d said something about only needing 1. He’d said, if I only need 1, he’s got a single barrel lying somewhere around the shop & he’d text me the link to buy said barrel the next day.
    On another occasion, I had questions about the threading on 1 end & about a nut I was looking at & whether or not that’d fit it. He really helped me out & I got everything figured out for what I need.
    So on multiple occasions, their staff has gone out of their way to help me & make sure I get everything I need w/ no mistakes!

    I bought two of these for a gunsmithing project and they are excellent!!! Very high quality product, I plan on buying from this company again. The only negative is they are out of stock frequently.

    I purchased the 357 magnum 6″ threaded barrel for a project I’m working on, I am a ways away from finishing my project so I haven’t got to fire any rounds through it yet. But the barrel is flawless, finish is great, the threading is spot on. Can’t beat these barrels for the price, and shipping is fast. They have a lot of calibers to choose from. I recommend Chaszel.
