The guys at the booth tell me they did not decide until the last minute, literally a week ago today, to show it. I find nothing on their website about it. I do have some pictures of the new action and will attempt to post them tonight.
https://defiancemachine.com/actions/Features of the new action (from Memory just by way of warning):
700 clone, mostly.
The medium length action weighed 1.48# on their scale.
The bolt is one-piece, fluted with more, narrower, and deeper flutes.
The bolt I.D. is also larger to reduce weight.
M-16 extractor
Integral recoil lug
Bolt release and stop are on the side of the rear action ring
The rear action ring is round, (not cut down like a 700) and there are cutouts machined into the sides for weight reduction.
Bolts are all machined to exactly the same length (within .001") to allow complete changeability.
I am sure I am forgetting things but I will try to catch up later on what I have forgotten. Pretty cool piece of work and I suspect I will be looking hard at them soon.
