What do we reckon to this?

VFC BCM, comes with an ETU. Seems to refer to pre-cocking as "pre-pull"

 

However the way to disengage it, is somewhat confusing. Surely it's not a case of letting off several bursts in full-auto!?

 

I understand holding the trigger for a moment (like on my Perun'ed G&G DMR) or a single quick burst of full-auto (like on my SSR4).

Thinking about it, it’s quite sensible; you don’t need precocking in auto, so I guess the etu senses this and disengages the feature.

Yeah, that bit I understand....however "several" individual trigger pulls?
