I have 2 of the armoured vehicle mounted PKT's to dispose of. These are the ones that go in the co-axial mount of a BMP-1, OT-90, SKOT-64 and possibly the T55/72 (not sure about these last two - you'd need to check first). They are electrically fired hence have no butts, pistol grips or triggers - see photos!
Both weapons are deactivated to latest UK standards and have appropriate certificates
