I think the Spector is the same gun as a VMX and same trigger. Stock screw go in at an upward angle. Like the Striker/Edge.The Webley Black Hawk I believe is the same gun as a Hatsan 95 and my Webly Tomahawk. Stock screws go straight in 90degrees to the gun.The barrel block on my 135 is longer than the VMX/Striker. Same length as on my Tommy.I'm trying to order wood Striker stocks for my VMX and Striker. Both their plastic stocks broke at the side screw holes. The problem is the VMX has a two piece cocking lever and the striker is one piece so the slots in the bottom of the stocks are different. I'm wondering if a metal pin thru the bottom of the stock will work with the VMX in a Striker stock.There's a longer trigger screw mod for the VMX/Striker. Got it in my VMX and it helps a lot but not like target grade. You can find the mod in the Turkish Gate. It was all the rage about a year ago.
