Bill, the two front beads are 1/4" and 7/16" from the bore. The letter from Parker said it left the factory with both 32" barrles choked full and full(280#8 pellets in a 30" circle at 40 yards) and 2 5/8" chambers. The order speciified no saftey and while it originally had double triggers it was converted with what looks like a Miller SST.
