TC & GPR different

[ebiggs1]

There has been some discussion on how close the Lyman GPR is to the Thompson Center Hawken in mechanicals. Although this is true they are not exact copies of each other. Just to clear up the difference here is a photo of each.

In my opinion neither the Lyman lock nor the trigger is up to the Thompson Center, although they are quite serviceable as they come.

The point they share in common besides obvious design knock-offs is that they both can be improved by replacement with better after market models. The "edge" one shares over the other isn't enough to make me keep either of them.

Big +1.

Flint locks made of pressed beer can lids and bent paper clips tend to be less reliable in use than those available from lock-only manufacturers. Having written that, the same budget-priced lock design - when adapted as percussion cap lock - functions blandly and uneventfully.

That's my story and I'm sticking to it.

I like neither design. Locks that have "V" springs will always remain in my rifles. It is much easier to modify spring tension than with a coil spring.

Not knowing what "beer can locks” you are referring to but Lyman locks can perform as well as anybodies lock.

Really, all I do is cut one coil or half a coil of and it seems pretty easy. I am not trying to promote either just showing the difference.

the real difference with the 2 is that the GPR has a slower twist. The locks are OK, not a siler, but they can be turned to work better. My dad gave his lock off his renegade to brad at cabincreek. He put a new frizzen and tuned it up and it is almost as nice as my lg siler

I've had no problems with either locks. My T/c rifles have never let me down.I rarley have any misfires and when I do it's usually my fault. Nice post ernie. :thumbsup:
