From L&R. The RPL line was developed in answer to tremendous customer demand for a better lock than those found on most factory muzzle loading rifles today. Each RPL lock is all American made by experienced craftsmen and backed by the reliable parts and service of L&R. These precision built locks feature competition strokes, bearing surfaced internals and forged "V" mainsprings. These locks are not "drop-ins". They do require some inletting to allow for the working parts. Patterns for wood removal will be provided in a booklet of instructions packaged with the lock. Depending  on skill level , they can be installed in 15 to 35 minutes using common chisels and gouges.

Replaces the CVA Hawken, Traditions, etc. Plate measures 5-1/16" x 31/32".  Right hand. N0. 42021

Because this unique lock style has an unusually large plate and features a compact internal mechanism, there is plenty of room to customize the plate and shape it to fit many different mortises ranging from the current size to as small as 4" x 7/8". This makes it a great option for antique restoration or some of the less common commercial muzzle loading firearms.  Plate interchanges with flint version.
