does not change the efficiency, i have hit over 60% with a 77k, the TX is not running quite as sweet with the same stroke and piston set port placement is for me nowt to worry about.

I was considering designing a sled system for the 77, one that could be locked also, theory being it totally isolated the action from the stock with the action being held true with no twist in any way.
