Well I bit the bullet
 

I went into the gun shop and ordered my Lyman Great Plains Rifle .54 flintlock LH (left hand). It should be in on Monday. I wanted a dedicated .54 PRB shooter so I decided not to fuss around with the Renegade. Even though I got a new stock for it. So with that being said, I am going to sacrifice my wallet a bit and let it go for $250 tyd if interested. (.54 Renegade flintlock). Now that's a good price so first come first served.
Now once I get the Lyman, What peep do you recommend?

Congrats. I have thought about getting the lyman peep site for my .54 Great Plains caplock. I don't know what other peeps are availiable for it.

I have the Lyman 57 on mine. I don't know how you could do any better. It's a great sight. Easy to adjust, and once you settle on a load and have it set for whatever range you want zero to be you can experiment with the scale to quickly click it up for a number of longer range zeros. Sort of like a BDC.

Good for you! I enjoyed my GPR FL but just didn't make any sense having a FL since i hardly ever have the real stuff on hand.

I sure like my Lyman. And if I were going to put a peep on it, it would be the Lyman 57. watch for them on Ebay.. the come up pretty cheap sometimes.

Lyman 57 I have one on my 54 Lyman works very well

I got an offer to but the rene. Someone is going to be happy with it.
