This nice percussion lock was made by Thompson Center, for their Greyhawk rifle. It is the same design as the lock used on Hawken, or Renegade rifles except in stainless steel and could be used on those rifles. The photo is reprentative! This used lock is in perfect working order, very good condition.
Right hand, the lock plate and hammer are factory engraved. This is a later T/C locks with the curled finger spur, and they require the new short nipple.
This lock has a powerful coil mainspring, fly detent for use with double set triggers, and it is tapped for an 8-32 lock bolt, sold separately.
