What could you do to protect the trigger assembly when out of the stock? Just in case it's in a hiking bag or worse and taken on a hike while apart. This would be a great trick too for shipping rifles to be worked on.
Small plastic container, rivet a velcro strap to it.
Contour to fit the action and voila, protected.
I know take apart rifles have been around since men have had rifles. They almost always involve an interface near the receiver.
And they all have some change in zero. Even if it is small, there is one
By separating the stock, all the important bits get to stay aligned and intact. Makes for a lighter less complicated package to boot.
I am about to venture into airline travel to get to F class matches (driving just eats too much time and money). For now, I have the big honking case but am looking into personal luggage that I can modify to ship rifles this very way.
Getting the rifle to like 36" saves a bundle in extra luggage costs. The rifle case is extra luggage AND overlength - yikes, pricey, pricey, pricey
But what happens when you arrive and get limited sight in time?
I know that my rifles go back together and are close enough that the first sighter is worthwhile.
See if any of these break down manf will give you a MOA guarantee for 1000yds?
Simple enough for any shooter with a properly bedded rifle to test. Two bolts and 1 minute of your time. It will either work or not.
If not, fix the bedding until it does...
