Have you ever received an old .22 rifle from your granddad as a hand-me-down and, when you looked it over, realized the only thing that needs replacing is the barrel? Running out of ideas, you talk with your local gunsmith, and he tells you that he can install a barrel liner and it will be as good as new. You accept. So, what does this process look like? What tools would you need for a job like this? Today, we are going to discuss the tools you need and how to prepare the barrel for drilling. Don’t worry! This will have two parts. The tools for this job include a 3/8” electric hand drill with variable speed, Brownells special 8mm .315 "diameter barrel liner with pilot, a sturdy bench vise with padded vise jaws, cutting oil, cleaner/degreaser, a brush to clear metal chips, .22 caliber cleaning rod with a bronze brush, 22 caliber headspace gauge, chambering reamer, large tap handle to drive the reamer, and finally some dummy rounds. To prepare the barrel, make sure the firearm is clear of any ammo and no ammo in the area. We can start to disassemble the firearm. Ensure that all parts that are attached to the barrel, externally and internally, need to be removed. Then clean the barrel thoroughly, removing any powder, lead, or any residue that is around the chamber. During this time, you will need to determine if the barrel needs to be removed from the receiver. Unless you have straight and clear access to the barrel chamber through the receiver. Make sure you note where the extractor cuts are. Along with the location and shape of any bullet guide or feed ramp. You do not have to be a professional artist, but do the best that you can and sketch out a picture of the muzzle crown that was used on the original barrel, noting if it is concave, convex, or counterbored. Also, make a casting of the original chamber. We will stop here. In part 2, we will discuss drilling the barrel, preparing the liner, bonding the liner, and finally doing the final fitting. |
