The Thompson Contender
and Encores are unique in that they are break open designs and have two firing pins, one
for centerfire and one for rimfire. Our insert barrels place the 22LR cartridge at the
extreme rear of the of the insert. After firing, the action is opened and the extractor
pulls the barrel insert out slightly where the fired 22LR case can be removed easily
without tools.
For break open rifles other than the Thompson
Contenders and Encores, a simple plug with a firing pin is used to detonate the rimfire
round. A rod is then used to remove the fired case. These barrel inserts are only
available in cartridges over 40 caliber. |
