Advice on Btc Spectre Mk2 (Ngrs) Precocking

[2Wris]

Hi Guys, 

 

Hope this is the right place to ask - I have recently had a BTC Spectre MK2 installed in one of my guns and am unsure how to disengage the precocking? It fires beautifully, but the gearbox appears to stay in a 'precocked' state at all times and I am surprised there isn't a way to let all that tension go at the end of a game day. I have looked through the manuals and cannot find anything on the topic, any help is appreciated.

 

Many thanks

Set precock to the semi position only and not have it on auto.  Fire an auto burst at the end of the day.
