UTG Pro AR-15 Extended Carbine Quad Rail – 10.5″ FSP Cutout
Features
- Extended drop-in quad rail for carbine-length AR-15 rifles with a fixed front sight base
- Rail extends beyond the front sight base for additional accessory mounting space
- Four Picatinny mounting surfaces provide 92 total rail slots
- Integral alignment ribs provide a secure fit around the barrel assembly
- Drop-in design installs without permanent barrel modification
- Precision machined from 6061-T6 aluminum
- Black anodized finish
- Designed and made in the USA
The UTG Pro Extended Carbine Quad Rail gives fixed-front-sight AR-15 carbines considerably more Picatinny mounting space than a standard carbine-length handguard. Its FSP cutout allows the rail to continue forward around the factory-style front sight base, providing additional room for lights, grips, bipods, and other rail-mounted accessories while retaining the existing front sight.
Note: Designed for carbine-length AR-15 configurations with a standard fixed front sight base. Verify handguard cap, barrel assembly, and front sight configuration before installation.
