I have a night vision kit from Nitesite. Viper kit, only 6 months old and only been on a rifle twice. As new no knocks dents or scratches. I would like £210, but open to sensible offers. Payment by PayPal only.

Hi Peter . Sorry for being so thick, but I assume from you response the adjustment screw can be unscrewed and removed via the access hole without stripping the gun down.

How can I contact bgaltd.

Hi many thanks for your reply. Very interesting. The RFD did fit a allen key headed cover screw which covers the adjustment whole to the transfer port adjustment.
