What’s Included
- Stag Arms STAG-15 Model 3 Post-Ban semi-automatic rifle
- 1 × Magpul PMAG 10 Gen M3 10-round magazine
This Model 3 is purpose-built for restrictive jurisdictions. The compensator in place of a flash hider, fixed M4-type stock, and 10-round magazine meet California requirements while maintaining familiar AR ergonomics.
The 16-inch 4140/4150 CMV steel barrel is chrome-lined for corrosion resistance and long service life. A 1:9" twist rate stabilizes a broad range of bullet weights, making the rifle versatile for training, target work, or duty use.
Upper and lower receivers are forged from 7075-T6 aluminum and finished with a durable black hard-coat anodizing. Direct-impingement operation keeps the rifle lightweight and parts-compatible with standard AR-15 components.
Diamondhead polymer flip-up sights provide a distinctive diamond-aperture sight picture and fold flat when an optic is installed. A full-length Picatinny rail on the upper receiver simplifies mounting red dots or scopes.
The rifle retains classic controls: A2 pistol grip, two-piece ribbed polymer handguard, manual safety selector, and STANAG magazine release, offering instant familiarity to anyone experienced with the AR platform.
