| Overall Length | 32.5″ – 35.75″ (stock collapsed/extended) |

This carbine uses a standard 16.1-inch barrel with a 1:7 twist rate, optimal for stabilizing both lighter .223 rounds and heavier 5.56mm ammunition. The rifle weighs in at a manageable 6.55 pounds unloaded, making it easy to handle for extended range sessions. The heart of the value here is the Colt name on a complete, functional rifle without the premium often attached to more specialized models. It’s mil-spec compatible, meaning a vast universe of aftermarket AR-15 parts from brands like Magpul, BCM, and Aimpoint will fit with little to no gunsmithing required. That said, the out-of-the-box configuration is more than capable for most shooters.
Who This Rifle Is For
This is the rifle for the shooter who wants a “do-everything” AR-15 from a legendary manufacturer without breaking the bank. It’s ideal for the first-time AR buyer seeking a trustworthy foundation, the budget-conscious prepper who prioritizes proven reliability, or the Missouri sportsman wanting a versatile carbine for varmint control. If you’re comparing a $600 budget build to a $1,500+ premium rifle, this Colt sits in a compelling middle ground—offering brand heritage and proven performance at a mid-tier price.
Pros & Cons: The Practical Tradeoffs
Pros: You get the Colt rollmark and its associated resale value and reputation. The Stealth Grey finish is a practical upgrade over standard anodizing. It’s a complete, functional system—just add ammunition and optics. The mil-spec design guarantees wide compatibility for future customization. For many, the biggest pro is peace of mind; this isn’t an unknown quantity.
Cons: At this price, you’re paying for the name and reliability, not premium features. Expect basic furniture: a standard M4 handguard, collapsible stock, and A2 pistol grip. The trigger is a standard mil-spec single-stage, which is functional but not target-grade. You could build a similar-spec rifle for less, but you’d sacrifice the factory warranty and Colt pedigree.
Frequently Asked Questions
Q: Is this a true “M4” carbine?
A: While it’s often called an M4 carbine colloquially, the Colt LE6920 is the semi-automatic-only civilian version of the military’s select-fire M4. It replicates the look, feel, and core functionality with a 16-inch barrel (the military M4 has a 14.5″ barrel with a permanent muzzle device).
Q: What does “MPS STG” stand for?
A: This is Colt’s internal model designation for this specific configuration. “MPS” likely denotes the model series, and “STG” is the abbreviation for the Stealth Grey finish. It distinguishes this model from other finishes in the LE6920 product line.
Q: Can I use .223 and 5.56 ammunition interchangeably?
A: Yes. The chamber is stamped 5.56mm NATO, which means it is safely designed to fire both higher-pressure 5.56mm rounds and the slightly lower-pressure .223 Remington rounds. The reverse (firing 5.56 in a .223-only chamber) is not recommended.
Look, if your goal is to own a dependable, no-nonsense AR-15 from the company that defined the platform, the Colt LE6920 MPS STG makes a strong case. It forgoes flashy upgrades to deliver core reliability at a price that underscores its bang-for-buck mission. This rifle is available at firearms-missouri.com for Missouri residents and nationwide, with an FFL transfer required for firearm purchases. Ready to see if this Colt fits your needs?
