The swap works just fine, except for cartridge lenght since the 7mm. magazine is some .120" shorter.
In my Colombian 7mm, the gas cylinder opening was large enough and
the headspace improved by .002".
Rifles are marked for caliber on receiver floor, and changed that to 8mm.
To remove old barrel, I cutted a circumferential groove on barrel very close
to the receiver, as to relieve some of the pressure.
The groove was cut with a hacksaw to approx. 1/8" depth.
Wrapped emery cloth to old barrel used a pipe wrench and vise.
It came out easily. new barrel installation was very easy as theads were
time correctly!
I think that you will be happy with it.
The kick, muzzle flash and action gas realese goes up considerably!
good luck!
