Critical Handguard Stabilization

The Gun Engineer Quad Rail End Cap delivers essential stability for your AR-15’s free-float system by mechanically locking the handguard against the receiver interface. This precision-engineered component prevents clocking movement during rapid-fire engagements or impact scenarios, maintaining consistent accessory alignment while creating a debris-resistant barrier at the assembly boundary.

Manufactured from aerospace-grade aluminum and protected by MIL-Spec hardcoat anodization, it withstands thermal expansion cycles and friction wear without compromising dimensional integrity.

Securement Features:

• Rotational Lock Design – Keyed interface prevents torque-induced handguard movement
• Precision Mating Surfaces – Machined to ±0.002″ tolerance for zero-gap assembly
• Debris Exclusion Flange – Seals handguard-receiver junction against particulate intrusion
• 6061-T6 Aluminum Core – Optimal strength-to-weight ratio without barrel harmonics effect
• Thermal Expansion Compensation – Radial gaps accommodate barrel heat transfer
• MIL-A-8625F Anodization – Type III Class 1 finish for permanent corrosion resistance
