Can't help with Tikka either, but..
I just picked one up (used) and it's a great looking handle.
Mine is for a LA LH 700...it comes in at a svelte 20.5 ounces with studs, but without a pad.
Mine is for an ultralight build, should be a fine stock for the purpose...Looks to be a well-built, stiff piece.
You should be happy with the choice.
Have you called Hightech? Their prices are decent.
