A3 Tactical Stribog Gen 2 Lower Receiver w/ LRBHO & Aluminum mag Release


This is an all new lower receiver for the Grand Power Stribog. It is designed to use the popular and well established AR fire control group and AR grips. The AR features bring almost limitless possibilities to your Stribog platform, allowing the user to customize the Stribog to suit their individual tastes and shooting preferences.


Additionally, this receiver uses the popular CZ Scorpion magazine instead of the OE Stribog magazine. The improved magwell angle and curved magazine has an inherent advantage over straight mags and has been proven to provide more consistent feeding, as well as better tolerance to various brands/types of ammo. 


Lower receiver ships complete with new steel Bolt-release lever, A3T mag release, new ILWT HK-style takedown pins, New stainless 1/4" grip screw, and selector detent with spring.

NOTE: A3 Tactical recommends a drop-in trigger for this application. Most Mil-spec triggers have a hammer width that is too wide for the Stribog bolt. Make sure the width of the hammer does not exceed .265" and please use anti-rotation pins if not using a drop-in trigger. This will eliminate the risk of "oblonging" the trigger pin holes in the receiver. 


NOTE: While some firearms have serialized lower receivers, the Stribog's upper is the registered receiver. This product is not a regulated or controlled item and is considered an accessory only. This item does not need to be shipped to an FFL.
