DANIEL DEFENSE M4 URG, V11 PRO

Product Description

The DANIEL DEFENSE M4 URG, V11 PRO is a complete upper receiver group built for shooters who demand accuracy and reliability. This 5.56 NATO configuration pairs an 18″ S2W profile cold hammer forged barrel with a rifle-length gas system for flatter trajectories and reduced recoil. It’s ideal for 3-gun competitors and long-range precision work.

Additionally, Daniel Defense’s proprietary Muzzle Climb Mitigator Gen II vents gas strategically to counter muzzle rise. This keeps your sights on target between shots. Faster follow-ups and tighter shot groups are the real-world result.

Furthermore, every Daniel Defense upper is hand assembled, quality assurance tested, and test fired before shipment. You’re purchasing proven performance from a manufacturer trusted by professionals and serious shooters nationwide.

Frequently Asked Questions

Q: What ammunition performs best in the 5.56 NATO chamber of this upper?

A: Standard 5.56 NATO and .223 Remington both function reliably in this upper. Quality mil-spec 55-grain and 62-grain loads deliver consistent accuracy. For 3-gun work, most shooters favor 55-grain rounds for flatter arcs and less recoil.

Q: What lower receivers does this upper receiver group work with?

A: This upper is mil-spec and accepts any standard AR-15 lower receiver. Daniel Defense uppers are compatible with Aero Precision, Colt, Spike’s Tactical, and other established mil-spec lowers. Simply verify your lower uses a standard mil-spec bolt catch and upper receiver pocket.

Q: Does this V11 PRO barrel outperform other Daniel Defense 5.56 barrels?

A: The 18″ S2W profile excels at longer ranges and 3-gun stages where flatter trajectories matter. The rifle-length gas system cycles softer than carbine-length peers. Daniel Defense builds each barrel to identical precision, so choice depends on mission, not quality.

Q: What’s included when I buy this complete upper receiver group?

A: You receive the assembled upper, barrel, bolt carrier group, charging handle, and gas tube—everything needed to mate to your lower receiver. No magazine or ammunition is included. You’ll need a stripped lower and a standard mil-spec bolt to complete your rifle.
