For the budget-minded, this rifle is a definite win, as it includes furniture from the popular B5 Systems. The B5 Systems SOPMOD stock recreates everything great about other SOPMOD stocks without the price tag. With a comfortable cheekweld, 6-positions of adjustment, and QD cups for sling attachment, the B5 Enhanced SOPMOD is one of the most popular stocks on the market, even for high end AR-15s. That’s why the military is quickly adopting B5 SOPMOD stocks onto many issued rifles. The Type 23 Pistol Grip is another noticeable upgrade over a standard rifle, as it improves the shooter’s wrist angle for modern shooting doctrine. An extended tang helps ensure proper indexing and aid in the overall ergonomics of your rifle.
Without a doubt, this is one of the most feature-packed—yet still affordable—offerings that Radical Firearms offers. The only thing you need to finish the build is a set of sights or an optic, which are all available right here at Primary Arms.
