Machined aluminum forearm gives your AK the same kind of tactical accessory mounting flexibility long available for the AR-15/M16 platform. Two-piece design clamps securely to the front barrel trunion and puts four, MIL-STD 1913 rails up front to provide plenty of space for mounting lights, lasers, optics, vertical grips, bipods, quick-detach sling swivels, and other accessories. Top rail won’t interfere with use of original iron sights; bottom rail has cutout to accommodate under-folding stock, and side rail allows clearance for side-folding stock. White, etched alphanumeric slot markings help you make sure accessories get reinstalled in the right locations after temporary removal. Mfg: Samson Manufacturing Corp SPECS: 6061 T6 aluminum, hardcoat anodized, matte black. Model 1 - 9¾” (24.8cm) OAL. Fits most full-size AK-47/AKM with fixed or folding stocks.
