My Colt HBAR A-2 recently started having an issue. After the last round is fired, the bolt stays open, however, when I place the gun in the rack, the bolt will close. It seems with a little "thump" on the butt stock, the bolt will close. A buddy at the range told me i had too much oil in the gun, and he's probably right. I was told to run the gun "wet" so i have been applying oil pretty liberally. Could too much oil cause this problem, or do i have another issue?

thats normal for about any semi auto firearm. with no magazine to keep the bolt catch in the up position any blow to the butt of the rifle will pull the bolt back enough for the catch to release. its got nothing to do with oil.
