Don't would be my advice, they need weight up front buddy, I had a mate machine up a weight to replace one of the hair curler sections in the silencer, made a world of difference to the accuracy...

Drop the short stroke, leave the guides in place, add weight to the silencer and set @ 10.5-11.0...

Ps, they're not much better in .22 either although they will shoot @ 11+ easier...
