Description
When you need a rifle that bridges the gap between a dedicated home defense tool and a reliable all-purpose carbine, you need a platform that’s ready from the moment you open the case. The Adams C.O.R. Ultra Lite AR-15, .223/5.56, 16.5″, Fixed Stock, 30rd is that rifle. It’s a factory-built, no-nonsense AR-15 carbine designed for immediate deployment, featuring a lightweight 16.5-inch barrel, a fixed A2-style stock for consistent shouldering, and a 30-round magazine capacity. This rifle is drop-in ready for Missouri home defenders and shooters seeking a dependable, straightforward carbine that prioritizes function over flash.
Let’s talk about what that means on the range or at the property line. The fixed A2 stock isn’t just for nostalgia—it provides a solid, unchanging length of pull. That consistency translates to faster, more instinctive shouldering when seconds count. Paired with the 16.5-inch barrel, you get a maneuverable carbine that doesn’t sacrifice too much velocity, making it effective for both close-quarters scenarios and mid-range target work. The barrel’s profile is engineered to shave weight where it matters most, up front, so the rifle feels balanced and quick on target. At a total weight hovering around 6.5 pounds unloaded, it’s easy to manage for extended drills or carrying on a sling.
The heart of any reliable AR is its compatibility. This Adams C.O.R. model is built to standard mil-spec dimensions, which is your guarantee of broad parts interchangeability. Want to swap the handguard? It accepts any standard AR-15 drop-in two-piece handguard system. Thinking about optics? The flat-top upper receiver is ready for your choice of red dot or scope mount. This mil-spec compatibility means you’re not locked into a proprietary ecosystem; you can build and accessorize with confidence using parts from trusted brands like Magpul, BCM, or Midwest Industries. The rifle ships with a 30-round magazine, giving you a full standard capacity from the start, and it’s priced at $1340.90.

Frequently Asked Questions
Q: Is the 16.5-inch barrel length legal without special paperwork?
A: Yes. A barrel length of 16.5 inches is above the federal minimum of 16 inches for a rifle, making this a standard Title I firearm. No NFA registration or tax stamp is required, which simplifies the purchase process. An FFL transfer is required for firearm purchases, as with any rifle.
Q: Can I use both .223 Remington and 5.56 NATO ammunition in this rifle?
A: Absolutely. The chamber is designed to safely fire both .223 Remington and the higher-pressure 5.56x45mm NATO rounds. This gives you maximum flexibility in ammunition selection based on availability and intended use, from training to defense.
Q: Is the fixed stock a permanent feature, or can it be replaced with a collapsible one?
A: The fixed A2 stock is a permanent part of the rifle’s buffer tube system. Converting it to accept a collapsible stock would require replacing the entire buffer tube and stock assembly, which is a gunsmithing task. This rifle is best for those who prefer or don’t mind the fixed stock configuration.
