I dura coated my original SBE barrel receiver. The blueing was getting thin. I also added an extra power recoil spring which I highly recommend. This one was a wedding gift from my wife.
A few years later when the SBEII came out I lusted over the 28" camo version and when I woke up to go duck hunting one morning it was waiting for me on the kitchen table.
On my SBEII I had Briley install a extended bolt release and I put in a Ballistic Specialties bolt on it. I also use ballistics Specialties tubes in everything. The bolt and bolt release are great for cold weather hunting.
