Tom Manner's at Manner's Stocks is in the process of coming out with replacement stocks for the Tikka T3 rifles. The first stock which is about done is the Manners MCS-T4 tactical stock. I'm working with Tom on a replacement hunting stock for my LH Tikka T3 lite using their MCS-SL hunting stock. Tom hopes to have the MCS-SL ready to go in a few months and LH versions will be no problems.
Also Pete Lincoln with Roedale Precision is in the process of creating a number of different bottom metal solutions for the Tikka T3's including an alloy factory replacement.
Below is a link to the snipershide forum thread that has pictures and details of what's getting ready to come out.

I'm looking forward to being able to upgrade my stock and bottom metal.
Just wanted to let you know!
