The UTG Pro RBUS1BM delivers mil-spec reliability with enhanced ergonomics for AR-15 and M16 platforms. This 6-position collapsible stock system provides precise length of pull adjustment while maintaining the durability standards required for professional applications. Black synthetic construction resists impact damage and environmental exposure better than standard polymer alternatives.
What Makes This Different
Built to true mil-spec dimensions, this stock kit ensures proper fit with standard carbine buffer tubes without the wobble common in commercial-spec alternatives. The reinforced synthetic polymer construction weighs 30% less than comparable aluminum stocks while providing superior impact resistance. Internal steel reinforcements at stress points prevent cracking under heavy use that destroys cheaper polymer stocks.Key Features
