Check out "The Dianawerk Collective "and Steve Kitching's "The Yellow Forum "lots of talk on both sites.Different # of lands and grooves on the Chi/Com barrels.Almost all of the BAM airguns are either RWS/Diana knockoffs or HW not much else is worth copying unless you count the poorly made Turkish Webleys................JMO..........Harold...........At least the Chinese copies don't have RWS barrel droop.I'd have no quams about owning a BAM 28/RWS350 or BAM 31/RWS48 Chinese barrels on RWS/Diana 34 +350 ONLY from late 2008 to present. German barrels 8 lands and grooves/ Chinese 12
