Night Vision Evolution Meets Precision Engineering

When special operations forces needed to merge precision day shooting with night fighting capability, this innovative SPR rail design provided the solution. Building on the proven Swan rail concept, this 17.5" variant incorporates a specialized front section designed specifically for the AN/PEQ-2 laser illuminator, though modern builders often adapt it for the current-generation PEQ-15.

Key Features

• Dedicated PEQ mounting section for optimal IR laser placement
• 17.5" overall length with .450" height increase
• Three cross-bolt receiver attachment points
• Dual flat head screw connection to handguard lugs
• Hard-coat anodized aluminum construction

Advanced Integration Engineering

In the evolving landscape of night vision operations, proper IR laser placement became crucial for success. This rail's specialized front section positions the PEQ device at the optimal height and forward position for both hand clearance and laser alignment. The removable rail section allows direct mounting of the laser illuminator, providing a more secure and lower-profile attachment than standard picatinny mounting.

The three-point receiver attachment combined with dual lug engagement creates an exceptionally rigid platform - crucial for maintaining laser zero during night operations. This mounting system evolved from extensive field testing, where maintaining IR laser accuracy proved just as critical as day optic zero. The Gen III handguard interface accommodates the larger barrel nut while ensuring perfect alignment of both visible and IR aiming devices.

Modern Adaptation

While originally designed around the AN/PEQ-2 used in early GWOT operations, this rail has found continued relevance with today's PEQ-15 users. The dedicated mounting section provides the same advantages of height and stability that made the original configuration so effective. For clone builders and professional users alike, this rail offers authentic capability alongside historical accuracy.
