Barrel Replacement Rolling Block Rifle

[SteveUSA1]

Barrel Replacement. Have a ' Baby Remington Rolling Block" and want to replace the exiting barrel with a custom made longer one. I will not change the .357 cal. Just longer barrel. Major surgery or a simple unscrew the old and screw in the new?

Replacing your rolling block barrel will require the services of a good lathe operator/gunsmith experienced at rebarreling rolling blocks.

Your gun is probably a Navy Arms .357 carbine, and the barrel threads are vee-metric rather than the standard USA 12 tpi square threads.

The barrel must be headspaced to your action, milled to fit the breech block, timed to orient the sights, sights installed, chambered, and test fired.  I'm not aware of any current sources for replacement barrels that will fit.  Many machinists will shy away from this project because it requires a gunsmithing license and liability protection.

If you have access to the lathe, and special tools, then YES, it's a simple operation.

Do you happen to be in  Florida?   I had a smith build a RRB for myself.  It came aout great.

I have done several of the cute little RBs that came from Uberti before they sold to Beretta. The barreling has to be done properly so that the breechblock in absolutely flush with the breech when the hammer is down. Then you do the chambering and cut the extractor slot. No big deal but a bit of work. I am doing a 7x57 on one of the "big brother" ones now.
