Guest pierce09 Posted June 19, 2018 Share Posted June 19, 2018 I've got a VFC GB and receiver'd MK18 Mod1 that I've built over the last few months. The gearbox is from my old VFC 416 that I purchased in the US so it'll need a lower spring in it to get it under 325/330 fps with .20s. Does anyone have any recommendations for a tech in the Cambridge/Huntingdon area that could change out the spring and get the rifle firing like a dream?

Supporters Prisce Posted June 20, 2018 Supporters Share Posted June 20, 2018 FireSupport are nearby, never used them myself, but a few people I play with have had them do the TM NGRS “upgrades” and have had no problems with them. Link to comment Share on other sites More sharing options...
