BKOs have a 2way valve, so they use a spring to return the ram. B2Ks have a 4way valve which uses air to operate the ram for the entire cycle. BKOs have a larger 'post regulated air' chamber then B2Ks but thats because of the BKOs Low Pressure Regulator set up. BKOs are limited in their rate of fire due to the design of both the LPR and valve assembly. B2Ks might not get as many shots per fill as the BKO but it is a much more consistant and reliable. BKOs tend to chop paint due to their design, they suffer from blowback much like the EM1, although Vapor Works makes a dual O-ring bolt that retails for under $30usd that will fix any blowback you might encounter with either the BKO or B2K. There is much much more for you to fully understand the differences but at the same time I will tell you they are very simular in function... Performance is another issue though.. I would suggest going to pbnation and take a look at the Indian Creek Designs/Bushmaster forum. Make sure you read the FAQ and the other stickies posted at the top before you post though. The regulars there dont take kindly to the repetive questions they see everyday. Just my $0.02
