Frequently Asked Questions

What makes the Colt 6940 considered one of Colt's best M4 developments?

The Colt 6940 is highly regarded for its innovative monolithic one-piece upper receiver, which provides a rigid, continuous rail system and a free-floated barrel. This design, combined with its reliable performance and updated specifications like the M16-cut bolt carrier group, positions it as a top-tier factory AR-15.

Why was the Colt 6940 previously unavailable?

The Colt 6940 faced market unavailability due to a patent dispute concerning its monolithic upper receiver design, specifically involving Lewis Machine & Tool (LMT). Following Colt's acquisition by CZ, these issues have been resolved, allowing for its return.

What are the key differences between new CR-prefix and older LE-prefix Colt 6940 models?

New CR-prefix Colt 6940s feature an M16-cut bolt carrier group for enhanced reliability, typically come with Magpul MBUS sights, and are available at a much lower street price. Older LE-prefix models might have different BCG profiles and were often sold with Matech sights at higher prices.

What is the significance of the monolithic upper receiver on the Colt 6940?

The monolithic upper receiver is a key feature, machined from a single piece of aluminum. It offers superior rigidity compared to traditional two-piece uppers and allows for a truly free-floated barrel, which can improve accuracy and provides a continuous mounting platform for optics and accessories.
