Description The Definitive Arms AKM4 Stock adapter series is the lightest and strongest way to allow the usage of M4/AR15 style stocks, buffer tubes, and pistol brace tubes on common AK variants with a simple to install completely drop in assembly. The Yugo Fixed Stock series version is compatible with original spec Yugo fixed stock AK variants (M72, M70, M77, M76, M21, M90, M91 and other fixed stock variants) Completely Drop-In part, installs in minutes with zero alterations or fitting required. * Machined from solid Aluminum. Anodized Finish (MIL-A-8625 Mil-Spec Hard Coat Anodized) Includes hardware and tool for installation (Alloy steel bolt, allen-key tool) Single bolt attachment design combined with aluminum sheer lug for a breaking strength that exceeds buffer tubes themselves. Aligns buffer tube closer to bore line for better recoil management via flatter recoil impulse. Increased stock height for improved use with optics equipped AKs and still allows comfortable operation with open sights. Accepts Mil-Spec and most after market buffer tubes, end plates, and castle nuts. Weight: 2.0 oz (including mounting hardware) * Note: 100% Drop in installation assumes you have an In-Spec rifle with proper rear trunnion, receiver dimensions. Some rear trunnion variations may require you to lightly fit or lubricate the wedge fit mating surfaces for a clean installation. No fitting is required on a quality in-spec properly built AK.
