I know this question has been asked before I want to replace my lock on my GPR flint lock with a L&R is there a video or a tectorial out there ?
No problem I like the rain guard on the L&RIf the L&R lock is designed to replace the GPR lock, you may have to so some minor trimming to get the new lockplate to fit the GPR lock mortice. It should be a very close fit.
What is the reason for replacing the old lock? No spark from a worn frizzen? Or something even worse?
I’ve installed a few L&R RPL flintlocks in Lyman rifles. Somewhat of a PIA. Lockplate doesn’t match Lyman factory mortice (too large in some areas, too small in others) plus it’s a crapshoot if it will line up with factory touchhole location. This has nothing to do with the wood you have to remove for the locks internal springs.I know this question has been asked before I want to replace my lock on my GPR flint lock with a L&R is there a video or a tectorial out there ?
Thank youI’ve installed a few L&R RPL flintlocks in Lyman rifles. Somewhat of a PIA.

As far instructions on how to install, most any out there showing how to install a lock will help. Me, I disassemble down to just the lock plate and see how things line up. Does it fit the lock plate mortise (none have for me)? Does it line up with the existing factory touch hole in barrel? Had one that was off quite a bit and had to move the barrel. Others have had similar problems. Once you have the lock plate properly inlet, you fit the other lock components into the stock just like with any other lock. I use Prussian Blue and a sharp chisel.
Here are a couple of photographs showing difference in the springs @Zonie is referring to between Lyman and L&R locks. Don’t have any issue with the wood removal required, but can’t say the same about the L&R lock plate’s crappy fit with the factory mortise. Unfortunately they are the only ones I am aware of that are making replacement locks for Lyman and TC.The L&R lock uses a flat mainspring that curves back on itself in place of the coil mainspring used in the GPR.
This flat spring requires removing quite a bit of wood in the bottom of the lock mortise for clearance.
