The Receiver Extension for the Grand Power Stribog is a popular addon for both function and aesthetics. The added length covers up the odd gap between the handguard and the end of the barrel while extending the rails and adding additional MLOK slots for greater accessory compatibility/options.
Weight: 1.8 oz
This part is manufactured in the USA from Nylon using a process called Multi Jet Fusion or MJF. The parts are then sandblasted, dyed and shotpeened for a strength and finish that is comparable to injection molded nylon. The part is black throughout.
MLOK NOTICE: Spacing between the added MLOK slot and the existing slots wasn't possible to be made to spec. within the given space. For this reason bridging MLOK accessories between the new and old slots likely will not work without modification to the accessory. It is recommended that 1-slot MLOK accessories be used on the new extension and 1-2slot MLOK accessories be used on the receiver. Bridging between the new and existing slots may require modification to the accessory or rail to fit.
INSTALLATION NOTICE: This part requires additional accessories to help secure it to the firearm. Please read the installation instructions listed in the Grand Power section of our INSTRUCTIONS page for more information.
Basically, the top of the extension is held in place by the factory front sight rollpin. This will hold the extension in place alone but to eliminate any wobble Haga Defense recommends securing the bottom of the extension with a rail mounted accessory such as an AFG or VFG. To be effective the accessory needs to have two separate locking tabs or screws that secure to both the Extension and the Stribog receiver creating a solid link between the two (see image below for examples). The examples below can be found on the Accessories page.
