Dark Storm Industries DS-15 M4 Assembled Fixed Magazine Lower

Description

The Dark Storm Industries DS-15 M4 Assembled Fixed-Magazine Lower gives you a purpose-built, drop-in solution for compliant fixed-magazine platform builds. Machined from durable billet-grade aluminum and finished for corrosion resistance, the DS-15 is engineered for reliable function, low weight, and clean lines that fit modern M4-style furniture and components.

This assembled lower ships complete and ready for assembly with standard M4 components — precise receiver geometry ensures consistent trigger and bolt alignment while the fixed-magazine configuration keeps the design compliant in jurisdictions with magazine restrictions. Ideal for range builds, duty rigs, and collectors who need a finished lower that accepts common M4 uppers and accessories.

Backed by Dark Storm Industries’ quality control, the DS-15 strikes an attractive balance between performance and value. Add your choice of trigger group, stock, and grip to complete the build — and pair it with Coastal Firearms’ selection of upper assemblies and compliant accessories.

The DS-15 Forged Lower Receiver is designed and patented by Dark Storm Industries to be compliant in all 50 states, including NY, CT, MA, NJ, CA, WA, and IL. This forged configuration combines reliability, compatibility, and compliance without compromise.
