Vltor AK Stock Adapter and Extension $76 Shipped Item is in excellent condtion. Comes with manual and installation parts. Here is some info from Vltor: The Adapter and Extension Combo is a direct replacement for the standard fixed AK-type stock. With this adapter installed, the user will have five stock positions, a watertight storage compartment that is accessible from the rear and an ambidextrous single-point sling mount, located near the firearm's receiver. This kit is the adapter/extension only, stock or QD sling-swivel not included. Will fit sheet metal AKM variants only, except the Yugo or the Iraqi Tabuk. The Adapter/extension has a MilSpec outer profile and will only accept Colt or Vltor dimensioned buttstocks. I accept check, money order, and Paypal. Paypal must include 3.5% ($2.66) Ships via USPS within 24 hours of receiving payment. I have positive feedback here as well as several other forums and auction sites, purchase with confidence.
