Alecto guide

Morning all

I've just joined and searched the workshop but couldn't find the info I'm looking for. Is there a guide to dismantling the Alecto? I could quite happily wade in remiving bits but I always like to make sure i'm doing thing properly rather than just wading in to repent at leisure.

I'm looking to seperate the top portion of the pistol containing the barrel from the remainder of the weapon with the minimum amount of hassle.

Thanks in advance for any assistance that you may be able to provide.

Cheers
Nigel
