After putting together the 8" BO, I remembered that I have a Iight and laser on a 16" gun that has no business being on it so I pulled them off to put on the 300BO. Having to pull the handguard again, I decided to change out the soft set screws and handguard screws with new ones. Thought that I had some crush washers for a 30 cal but only 223 washer. If I can get to the range on Sunday to test the gun I will put a can on it.
