its designed to be a top performer on co2.
My only advice to future potential SP1 users. Dont upgrade the reg, bolt, board. The stock reg is designed the way it is to ensure safety measures and work on both co2 and compressed air. Aftemarket bolts get rid of the guns anti-chop features, new boards also get rid of the anti-chop feature of the stock board/bolt combo.
