Jing Gong AK74UN M4 Stock Adapter – Complete Kit

The Jing Gong AK74UN M4 Stock Adapter transforms your AK platform rifle into a more ergonomic, modern platform. Whether you’re running a skirmish loadout or building a DMR, swapping the fixed AK stock for an adjustable M4 unit gives you shorter profiles in CQB, easier storage, and better cheek weld consistency across different shooting positions.

Key Features

• Complete adapter kit – no hunting for parts
• 6-position adjustable stock compatibility – fits most standard M4 stocks
• QD sling attachment point – quick-detach ready
• Full hardware included – adapter, tube, screw, and washer
• Drop-in installation – no permanent modification required

Real-World Use Cases

CQB skirmishers benefit most from the shorter, collapsed position when moving through tight indoor venues. Milsim players appreciate the adjustability for different kit configurations. Long-range shooters gain a stable cheek rest with adjustable length-of-pull. Hybrid loadouts—mixing AK ergonomics with M4 modularity—have become increasingly popular in UK airsoft.

Technical Specifications

Compatibility & Upgrades

This adapter is designed for the Jing Gong AK74UN platform. Most standard M4 stocks—from budget polymer to high-end military-spec aluminium units—will mount without issue. The included QD point accepts standard 1.25″ sling attachments. If you plan to run a heavy optic or magnified sight, ensure your chosen stock tube has adequate picatinny real estate or use a side-mounted rail adapter.

UK Legal & Site Notes

This is a mechanical upgrade—fully compliant with UK airsoft regulations. Two-tone or real-steel finish stocks are permitted in the UK provided the overall replica meets your site’s chronograph standard (typically 500 fps on 0.20g BBs for AEGs). Confirm your site’s rules on M4 ergonomic features before play.
