No. Since what gets modified in the CM300 is effectively the same part as the CP4, you'd have to mod the guns the same way. And since mounting the gun requires a decent amount of grip, I'm not sure that you'd be able to do so and not affect the capsule's ability to function as designed. Besides, the mod was an attempt at making the mic smaller for lower profile applications... not sure you'd have to worry about that if your choice of mic was the shotgun.
So what, specifically, is the difference between the Franken Naks I got from you OCanis, and the mod that Busman does?
Termination?
