DDM4 V7: A Reliable 5.56 Platform for Tactical Builds
The DDM4 V7 is a no-nonsense AR-15 rifle built for performance. Its 16″ cold hammer-forged barrel and M-Lok rail system balance durability with modularity, making it ideal for range use, competition, or defensive applications. Chambered in 5.56x45mm NATO (.223 Remington compatible), it feeds reliably from standard 32-round magazines. This rifle ships with a threaded barrel (1/2×28) for suppressor or muzzle device compatibility.

Feature Breakdown
The cold hammer-forged barrel provides consistent accuracy and extended service life. The chrome-lined bore resists fouling and corrosion, even with high-volume shooting. A mid-length gas system reduces felt recoil compared to carbine-length setups, improving follow-up shot control.
M-Lok slots along the rail allow direct attachment of lights, grips, or other accessories without bulky adapters. The slim-profile handguard maximizes grip options while minimizing added weight. Machined aluminum construction ensures rigidity under hard use.
Upper and lower receivers feature a precision fit to eliminate play between components. Controls include an ambidextrous safety selector and oversized magazine release for gloved-hand operation. The rifle ships with a standard carbine buffer system compatible with most aftermarket stocks.
A threaded muzzle accepts common flash hiders, compensators, or suppressors (adapter may be required). The 1:7 twist rate stabilizes both lightweight varmint rounds and heavier 77-grain projectiles. Test-fired at the factory to ensure proper cycling before shipment.

This rifle accepts all MIL-SPEC AR-15 components:
- Standard AR-15 lower parts kits

Installation Overview
No assembly required – the rifle ships fully functional. Field-stripping follows standard AR-15 procedures: remove takedown pins, separate upper/lower, and clean barrel/chamber as needed. Apply light lubrication to the BCG rails and cam pin during routine maintenance.
