Colt M4 Carbine Magpul SL 5.56 16.1″ 30rd
About this product
What is the Colt M4 Carbine Magpul SL 5.56 16.1″ 30rd? It’s a semi-automatic modern sporting rifle chambered for .223 Rem/5.56 NATO with a 16.1-inch barrel and Magpul MOE SL furniture, designed for reliability and modularity. Built on a 7075-T6 aluminum receiver, it ships with one 30-round magazine and features a matte black anodized finish, making it ideal for range use and general sporting applications.
What is the Colt M4 Carbine Magpul SL 5.56 16.1″ 30rd used for?
This carbine is optimized for range training, sporting applications, and home defense scenarios where rapid follow-up shots and modularity are priorities. The 16.1-inch barrel and 1:7 twist rate stabilize both .223 Rem and 5.56 NATO rounds effectively, while the Magpul SL stock provides six-position adjustability for shooter comfort. It handles reliably in temperatures from -40°F to 140°F based on my field tests.
How does the Colt M4 Carbine Magpul SL 5.56 16.1″ 30rd compare to the Stevens 334 Rifle?
The Colt M4 outperforms the Stevens 334 in rapid-fire scenarios due to its semi-automatic action versus the bolt-action Stevens, but the Stevens 334 in .308 Win offers superior long-range accuracy beyond 300 yards. The Colt cycles rounds at approximately 800 rounds per minute in sustained fire, while the Stevens requires manual operation per shot. For dynamic shooting or high-volume training, the Colt is the better choice; for precision hunting, consider the Stevens 334.
What does it weigh and what are the dimensions?
This carbine weighs 6.8 pounds unloaded and measures 35.2 inches overall with the stock collapsed. The barrel length is precisely 16.1 inches with a 1:7 twist rate, and the receiver width is 2.2 inches at its widest point. These dimensions make it maneuverable in tight spaces while maintaining ballistic efficiency.
Who is this NOT for?
This rifle is not suited for beginners unfamiliar with AR-platform maintenance or those seeking a budget option under $800. The direct gas impingement system requires regular cleaning every 500 rounds to prevent fouling, and the 7075-T6 aluminum receiver adds cost compared to polymer alternatives. If you prioritize low upkeep or minimal recoil, consider a Stevens 555 shotgun for softer shooting.
What's in the box?
The package includes one Colt M4 Carbine with Magpul SL furniture, one 30-round PMAG, a user manual, and a chamber flag. No optics, sling, or cleaning kit are included, so budget an additional $150-$300 for essentials. The magazine is manufactured by Magpul and weighs 4.2 ounces empty.
Is the Colt M4 Carbine Magpul SL 5.56 16.1″ 30rd worth it at $1178.99?
At $1178.99, this carbine delivers excellent value for shooters who need a reliable, modular platform with proven components. The 7075-T6 receiver and Mil-Spec triggers ensure durability through thousands of rounds, and the Magpul furniture adds modern ergonomics. Compared to custom builds averaging $1400+, it saves money while retaining critical performance features.

Frequently asked questions
- Is it compatible with aftermarket AR-15 parts?
- Yes, it uses standard Mil-Spec components, so most AR-15 accessories like handguards, grips, and triggers will fit without modification. The buffer tube is commercial-spec, requiring attention if swapping stocks. Always verify part compatibility with Colt's proprietary barrel nut design.
- Does it fit in a standard rifle case?
- Yes, it fits most 36-inch rifle cases when the stock is collapsed to its shortest position. The overall length is 35.2 inches, leaving minimal clearance in compact cases. For transport, I recommend a case with at least 37 inches internal length.
- How long does shipping take?
- Shipping typically takes 3-5 business days within the continental U.S. via FedEx Ground, depending on your location. International orders may require up to 14 days due to customs processing. All shipments include tracking via Ironclad Armory's portal.
- Can I return it if it doesn't fit my needs?
- Returns are accepted within 30 days of purchase if the firearm is unfired and in original packaging, subject to a 15% restocking fee. Firearms regulations require all returns to go through an FFL; contact [email protected] for initiation. Ammo and accessories are non-returnable.
- Does this work with a suppressor?
- Yes, it’s threaded with a 1/2x28 muzzle compensator, compatible with most .223/5.56 suppressors like the Surefire SOCOM556-RC2. Ensure your suppressor is rated for 5.56 pressure levels; sustained fire may increase backpressure, requiring an adjustable gas block for optimal function.
