If the marker is legal (no bounce etc...) and he can get 28 bps then respect to him. I've never used a DM4 so is there some bounce issue I'm not familiar with?
And if it bounces it's technicaly illegal and goes back into the "category 5 illegal firearms" argument. If a marker can be set up to do this then it's more than just tournament illegal...... so most top end markers could be in the crap if someone decided to make an issue out of it. (or if there was an accident/offence involving a bouncy marker).
