BP1212 .22 Caliber Rimfire Barrel Liner - 27" Length

Button rifled. To install, remove barrel from actions, observe the original chamber, the cut of the extractor notches, and determine if the rim of the cartridge is flush or countersunk. With a 5/16” drill, start from muzzle of barrel ad drill as far as possible. Braze a ¼” rod to the back of the drill and finish drilling. If liner binds or is tight, polish the outside until it can be inserted full length of the barrel. The fit should be close for good results. If the liner fit is satisfactory, solder or epoxy the liner into the barrel. After liner is installed, chamber it with a #1 wire drill for a .22 short or .22 long.
