Strike Industries AR Castle Nut & Extended End Plate Steel Blue

The Strike Industries AR Castle Nut and Extended End Plate delivers enhanced functionality and distinctive blue anodized finish to AR-15 platform builds. This steel construction upgrade provides multiple sling attachment points and improved aesthetics over standard mil-spec components.

What Makes This Different

The extended end plate design incorporates dual QD sling swivel attachment points, eliminating the need for separate sling mounts. Strike Industries engineers the castle nut with precise threading and anti-seize coating for smooth installation and removal. The blue anodized finish provides corrosion resistance while adding visual appeal to custom builds.

Key Features

• Steel construction with blue anodized finish for durability and corrosion resistance
• Extended end plate with dual QD sling swivel mounting points
• Anti-seize coating on castle nut threads prevents galling
• Standard mil-spec threading fits all AR-15/M4 buffer tube assemblies
• Precision machined surfaces ensure proper torque specifications
• Low-profile design maintains standard buffer tube length
• Compatible with all standard AR-15 buffer systems and stocks

Field performance shows reliable function across temperature extremes and high round counts. The steel construction withstands the stress of rapid-fire sequences and maintains proper buffer tube retention under recoil forces. Competition shooters benefit from the quick-detach sling points for stage transitions, while tactical users appreciate the secure mounting options for single and two-point sling configurations.
