Anodized aluminum adapter block. Made to insert and fill the angled cut on Vepr rifles so that standard format AK stocks and accessories can be installed. Does not require modification to the rifle. Clamps firmly in place under the grip nut. Will fit older Robinson Arms models.
Like any aftermarket AK accessory, some fitting may be required. Receiver internal dimensions will be reduced by 1.5 millimeters on the sides and bottom. Most fixed AK stocks will need to be modified to fit this slightly smaller space. The Vepr Receiver Adapter Insert will also allow the mounting of a Rifle Dynamics AKM4 stock adapter. The AK to M-4 adapter requires removing 2mm of material from the bottom of the L bracket that mounts inside the receiver. This is easily done at home with a belt sander or bench grinder.
