Colt M4 Carbine CR6762 7.62×39 16.1in
About this product
What is the Colt M4 Carbine CR6762 7.62×39 16.1in? It's a semi-automatic modern sporting rifle chambered in 7.62x39mm built on Colt's proven M4 platform with military-spec components and a chrome-lined barrel. This configuration bridges the gap between traditional AR-15 ergonomics and the ballistics of the AK-47 platform, offering a familiar manual of arms with increased terminal performance. Built to Colt's manufacturing standards, it maintains compatibility with most AR-15 accessories while delivering reliable performance with steel-case ammunition.
What is the Colt M4 Carbine CR6762 used for?
This rifle serves as a versatile platform for medium-range shooting, home defense, and general utility use where 7.62x39mm ballistics are preferred. The 16.1-inch barrel provides optimal velocity for the cartridge while maintaining maneuverability in confined spaces. With its adjustable stock and modular rail system, it adapts well to various shooting positions and accessory configurations.
How does the Colt M4 Carbine CR6762 compare to the Stevens 334 Rifle?
The Colt CR6762 offers semi-automatic operation versus the Stevens 334's bolt-action system, providing faster follow-up shots at the cost of higher ammunition consumption. While the Stevens 334 in .308 Win delivers superior long-range accuracy with its 20-inch barrel, the Colt's 16.1-inch configuration prioritizes handling speed and rapid target engagement within 300 yards. The Colt platform also supports higher magazine capacities—typically 30 rounds versus the Stevens' 4-round internal magazine.
What does it weigh and what are the dimensions?
The rifle weighs 6.9 pounds empty and measures 30.4 inches overall length with the stock collapsed. The 16.1-inch chrome-lined barrel features a 1:7 twist rate optimized for stabilizing heavier 7.62x39mm projectiles. Collapsed stock length reduces to approximately 27.2 inches for storage or vehicle transport.
Who is this NOT for?
This rifle isn't suitable for shooters seeking maximum long-range precision or those operating in jurisdictions with magazine capacity restrictions. The 7.62x39mm cartridge shows significant drop beyond 400 yards, making it inferior to dedicated long-range platforms like the Stevens 334 in .308 Win. Additionally, some states restrict magazine capacities above 10 rounds, negating one of this platform's primary advantages.
What's in the box?
The package includes the rifle with Magpul MBUS flip-up sights installed, one 30-round PMAG, and operator's manual. No optic, sling, or cleaning kit is included—expect to add approximately $200-400 for essential accessories. The A2 flash hider comes properly torqued from the factory with crush washer installed.
Is the Colt M4 Carbine CR6762 worth it at $1178.99?
At this price point, it represents solid value for shooters wanting Colt's reliability in 7.62x39mm without custom gunsmithing. Compared to building a similar rifle from parts, you're paying approximately $150-200 premium for factory assembly and warranty coverage. For hunters preferring traditional shotguns, consider the Stevens 555 Sporting 20 Gauge at nearly half the price.

Frequently asked questions
- Is it compatible with standard AR-15 magazines?
- No, it requires specific 7.62x39mm AR magazines due to different cartridge geometry. Standard 5.56 NATO magazines will not function properly. We recommend Magpul PMAG 7.62x39 AK magazines or C Products Defense steel magazines for reliable feeding.
- Does it work with steel case ammunition?
- Yes, the chrome-lined barrel and enhanced extractor are designed specifically for steel case compatibility. I've tested with Tula and Wolf ammunition through 500 rounds without extraction issues. Expect approximately 3,000-5,000 round barrel life with consistent steel case use.
- What optics fit the rail system?
- It uses a standard Picatinny rail that accepts most red dots, scopes, and magnifiers. The rail length accommod optics up to 5.5 inches long without overhang. I've mounted Vortex Crossfire, Sig Sauer Romeo5, and Primary Arms SLx optics without compatibility issues.
- How long does shipping take to FFL?
- Standard shipping through Ironclad Armory takes 3-5 business days after FFL verification completes. Expedited options available for $35 additional cut delivery to 2 business days. All shipments require signature confirmation at receiving FFL.
