The Victor Company FRGD 556 13.7" complete upper assembly delivers optimized ballistic performance in a compact package designed for modern sporting rifle platforms. This precision-engineered upper features a mid-length gas system that balances reliability with reduced felt recoil across various ammunition weights.
What Makes This Different
The 13.7-inch barrel length represents the optimal balance between velocity retention and maneuverability, maintaining over 95% of full-length barrel performance while reducing overall weapon length by 6 inches. The mid-length gas system provides smoother cycling compared to carbine-length systems, extending component life and improving accuracy potential. Precision manufacturing tolerances ensure consistent lockup and repeatable zero retention.
Key Features
- 13.7-inch chrome-lined barrel with 1:7 twist rate optimized for 55-77 grain projectiles
- Mid-length gas system reduces bolt velocity and improves reliability
- Forged 7075-T6 aluminum upper receiver with M4 feed ramps
- 15-inch free-float handguard with M-LOK attachment points
- Includes bolt carrier group and charging handle
- Compatible with standard AR-15 lower receivers
- Magpul Flat Dark Earth finish for corrosion resistance
Field testing demonstrates consistent sub-2 MOA accuracy with quality ammunition, making this upper suitable for competitive shooting, hunting applications, and tactical use. The mid-length gas system cycles reliably with both standard and match-grade loads while reducing brass ejection distance. Weather-resistant coatings protect against moisture and environmental contaminants during extended use.
