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.
