Glock OEM Firing Pin Channel Liner
Manufactured by Glock
Glock factory Channel Liner. This is a standardized part across all Glock models. If you are installing this liner yourself, you should use a Glock Channel Liner tool. It’s very easy to ruin a channel liner install and permanently damage the liner. It’s also a pain to remove a busted liner. Always have the right tool for the job, as they say!
