Description
Picture this: a threat emerges in the low light of your property. You need a rifle that’s ready, not one you have to build. The Colt LT6720-R M4 AR-15 5.56/223 16″ Barrel BUIS Sights, Troy Battle Rail Rogers Stock Magpul Furniture, 30 Round Mag is that rifle. It’s a factory-configured, duty-ready AR-15 platform built on Colt’s legendary M4 legacy, featuring premium aftermarket components for immediate deployment. This 16-inch barreled carbine arrives with a 30-round magazine, backup iron sights, and a suite of Magpul and Troy enhancements—it’s drop-in ready for serious use.
When it comes to home defense or property security, hesitation is not an option. The Colt LT6720-R eliminates that hesitation. Starting with the proven Colt M4 upper and lower receivers, this rifle is built to mil-spec standards, ensuring reliability you can bet your life on. The 16-inch chrome-lined barrel provides the ideal balance of maneuverability and ballistic performance for the 5.56x45mm NATO/.223 Remington cartridge. It’s a system designed for real-world application, not just the range. At $1253.20, this package delivers value that’s hard to match when you consider the cost of the individual upgrades.
The key features begin with the handguard. Colt ditched the standard plastic for a robust Troy Battle Rail. This free-float M-LOK compatible rail gives you a solid, stable platform for mounting lights, lasers, or grips without affecting barrel harmonics. Up top, you have a set of Troy folding backup iron sights (BUIS)—they’re always there if your optic fails. The furniture is all Magpul: an MOE pistol grip for superior control and a Rogers Super-Stock for a solid cheek weld and quick length-of-pull adjustments. The combination is intuitive; everything fits where your hand expects it to be.
Here’s the thing—this isn’t a parts bin special. It’s a coherent build where every upgrade serves a purpose. The Magpul MOE grip reduces felt recoil and improves handling, while the Rogers stock is a proven design favored by professionals for its simplicity and reliability. The Troy rail and sights are bombproof. This rifle speaks the language of utility. It weighs in at approximately 6.5 pounds unloaded, making it easy to handle for extended periods. And with its mil-spec compatibility, you can easily swap components with a vast universe of AR-15 accessories from brands like SureFire, Streamlight, or EOTech.

Frequently Asked Questions
Q: Is the handguard truly free-float?
A: Yes. The installed Troy Battle Rail is a free-float design, which means it only contacts the barrel nut, not the barrel itself. This improves accuracy by preventing pressure on the barrel from slings, grips, or bipods.
Q: Can I use .223 Wylde or 5.56 ammunition in this rifle?
A: Absolutely. The chrome-lined barrel is chambered to safely and effectively fire both 5.56x45mm NATO and .223 Remington rounds, giving you maximum ammunition flexibility.
Q: Are the iron sights included and installed?
A: Yes. The Troy folding backup iron sights (front and rear) come installed from the factory, providing immediate sighting capability the moment you take possession.
