Yea I thought about mounting them to the frame instead of the LCA but didn't. I think there may be some benefit to enlarging the strike plate as well, when squishing the soft timbrens, they will conform around the narrow strike plate, but this may be a good thing, allows a little more compression of the bumpstops. I am on my second set of timbrens, the first set showed no signs of wear but they were seized to the LCA so I had to rip the rubber from the threaded metal collar to remove them from my old LCA's so timbren sent me a new set because they consider that a failure(great customer service).
