CAA AKTM Aluminum Tube for Milled AK-47/74 Receivers

Turn a classic milled-receiver AK into a collapsible, AR-style carbine without losing strength—or adding bulk.  The AKTM replaces the fixed rear tang with a rigid billet-aluminum, 6-position buffer tube that takes any mil-spec M4 stock, giving armor-wearing or smaller shooters instant length-of-pull adjustment.  Two oversize screws anchor the adapter directly to the receiver for a rock-solid lock-up, and an internal sealed storage well keeps a cleaning kit or batteries dry.  Despite its toughness, the tube weighs only ≈ 184 g and measures 190x30x37 mm, so the rifle’s balance stays neutral.  A built-in QD sling socket lets you swap shoulders fast, while the higher, flatter stock angle delivers a better cheek weld and recoil line than surplus folders.  If your Bulgarian, Russian or SAM-7-type AK has the milled rear-block, the CAA AKTM is the quickest path to modern ergonomics.
