About Duostock Designs Inc
- Patented design provides maximum comfort, speed, and freedom of movement for operators wearing body armor in CQC situations. Same topside contours as a standard M4 carbine stock allow the shooter to maintain a solid cheekweld when firing, but overall length is slightly shortened to maintain correct length of pull. The deeper, curved underside is angled so the lower tip rides comfortably on the upper chest or collarbone in a forward, high carry position near the dominant eye; keeps the sights and barrel close to the line of sight, ready to be engaged with minimal head movement. Forward carry also provides better armor protection than the traditional angled stance that leaves the vulnerable arm holes exposed to threats. Made of lightweight, glass reinforced composite polycarbonate specially formulated for maximum impact and heat resistance. Reinforced at stress points for added strength. Aggressive checkering on contact surfaces minimize slippage. Matte black finish accepts most paints, so you can customize the color of your Duostock to fit your tactical requirements. Universal fits all M4-type buffer tubes. Sand interior to fit oversized tubes. Colt model provides a snug fit without play on the narrower-diameter buffer tube of Mil-Spec M4 carbines.
