Matt:

You have now found the universal disclaimer for product liability. Everyone
does this and your logic is not flawed.

The US government made a modification for the US Navy to convert the M-1
rifle from 30.06 to 308 Winchester some years ago. This is a case hardened
part that inserts into the chamber. The magazine well also had an insert to
accomodate the shorter cartridge.

However, with European standards and especially the lack of uniformity
between Russian Manufacturers, would not attempt to use the chamber insert
as provided at a gun show until I had a competent gunsmith look at it and
test the modification with proof loads. Better safe than sorry as your face
is next to 46,000 psi and is hardly worth the lesser expense given medical
bills these days.
