Description
Picture this: you’re clearing a property line after a storm, rifle slung, when movement in the thicket catches your eye. You need a platform that’s instantly familiar, utterly reliable, and ready to address a threat at a moment’s notice. That’s the domain of a proven carbine. When it comes to home defense or rural property security, having a rifle that operates like an extension of your will isn’t a luxury—it’s a practical necessity. You need a tool that works, every time.
The Bushmaster A3 Carbine .223/5.56 16″ Barrel Detachable Carry Handle 30 Rd Mag is a classic, mil-spec direct impingement AR-15 platform carbine. It features a 16-inch chrome-lined barrel, a detachable carry handle with integrated A2-style rear sight, and ships with a 30-round magazine. This rifle provides a proven, no-frills foundation for defense, sport, or customization, available at firearms-missouri.com for Missouri residents and nationwide.
Built on the legacy of reliability, this Bushmaster A3 gets the fundamentals right. The heart of the system is its 16-inch, chrome-moly steel barrel with a 1:9 twist rate. This twist is a proven workhorse for stabilizing a wide range of common .223 Remington and 5.56x45mm NATO ammunition, from lighter 55-grain rounds to heavier 62-grain loads. The chrome lining isn’t just for show—it resists corrosion and makes cleaning fouling a simpler task after a long day at the range. With an overall length of just 32.5 inches, this carbine balances maneuverability in tight spaces with the ballistic efficiency of a full rifle cartridge.
The defining feature is the classic detachable carry handle, which houses a fully adjustable A2-style rear sight. This setup provides an immediate, robust iron sight solution right out of the box—no gunsmithing required to get on target. The carry handle is secured via a mil-spec Picatinny rail, so when you’re ready to mount an optic, you simply remove it to reveal a flat-top upper receiver. This gives you a clean slate to install a red dot, scope, or backup iron sight system of your choice. The rifle’s controls are all standard AR-15 fare, meaning any training or muscle memory you have with the platform translates directly. The 6-position collapsible stock allows for a solid fit for shooters of various sizes and when wearing body armor or winter gear.
Here’s the thing—this is a rifle built for work. The lower receiver is compatible with a vast ecosystem of standard AR-15 parts and accessories. Want to swap the handguard for a free-float M-LOK system from a brand like Magpul or Midwest Industries? You can. Thinking about a different trigger or a ambidextrous safety? The platform welcomes it. This inherent compatibility is a huge part of its lasting value. The included 30-round magazine gets you started, but the rifle functions flawlessly with any USGI-spec or PMAG-style magazine.

Frequently Asked Questions
Q: Is the carry handle really removable for an optic?
A: Yes. The carry handle is secured to the Picatinny rail on the flat-top upper receiver with two screws. Removing it reveals a full-length rail ready for a red dot, scope mount, or flip-up rear sight. The front sight post remains, but it’s low-profile and often co-witnesses perfectly with a red dot sight.
Q: Can this rifle safely fire both .223 and 5.56 ammunition?
A: Absolutely. The chamber is rated for 5.56x45mm NATO, which means it can safely fire both 5.56mm and .223 Remington rounds. This is a key feature, giving you the flexibility to use whatever quality ammunition is available or best suits your purpose, from training to defense.
Q: What’s included when I purchase it?
A: The rifle ships with one 30-round magazine and the detachable carry handle installed. As with all firearm purchases, an FFL transfer is required. You’ll need to arrange for the shipment to go to a licensed dealer in your state for the background check and pickup.
