Bio-BBs from G&G are characterized by excellent surface processing and first-class flight behavior. Compliance with the permissible manufacturing tolerances is strictly controlled, so that use with 6.01 or 6.03 precision barrels is possible without any problems. In our opinion, they are the best organic BBs currently available on the market. In contrast to the "organic" BBs from other manufacturers, these are actually 100% biodegradable, in a conventional compost heap the BBS decompose completely within about 120 days.
