Ok, forgive me but my google fu is week today. I ordered the JM Pro 24" Barrel for my 930 (came with the 28" ported Barrel). When I was looking at the 24" Barrel, I saw that this barrel does not have the spring on the muzzle side of the gas block. The Barrel did not come with a piston but does have the screw in plug on the muzzle side of the gas block.
So do I take the guts out of 28" Barrel and move them to the new one, or is it safe to shoot with just the piston and barrel as it stands?
Thanks
