I recently purchased two new firing pin assemblies for my Rem 700's. One was for and older 700 and one was to replace the jlock in a newer one. Both are fluted steel pins with 2 lb stronger springs and aluminum bolt shrouds.

The look great and work great and came from Gre'-Tan Rifles in Kersey CO. phone is 970-353-6276

I just like to pat a guy on the back that makes very high quality parts.
