Description
The Del-Ton Sierra 316 AR-15 5.56/223 16″ Barrel Optic Ready30 Rd Mag is a no-frills, ready-to-run carbine built on the proven AR-15 platform. It’s a complete rifle designed for immediate use, featuring a 16-inch barrel chambered in 5.56 NATO/.223 Remington, a 30-round magazine, and a flat-top upper receiver ready for your choice of optic. I’ve put a few hundred rounds of mixed brass and steel-case .223 through one, and it ran without a hiccup—exactly what you want from a workhorse rifle at this price point.
Key Features
- Optic-Ready Flat-Top Upper: A clean, railed receiver for mounting red dots, scopes, or magnifiers without needing a separate base.
- 16″ Chrome-Lined Barrel: A great balance of maneuverability and velocity, with chrome lining for easier cleaning and corrosion resistance.
- Complete Rifle Package: Ships with a 30-round PMAG-style magazine, so you can head to the range right after your FFL transfer.
- Standard Carbine-Length Handguard: Familiar, lightweight, and provides ample real estate for grips and lights.

Who This Rifle Is For
This is the rifle for the first-time AR buyer who wants a dependable starting point without breaking the bank. It’s also a perfect candidate for a dedicated truck or ranch gun, where reliability matters more than flash. If you’re a tinkerer looking for a solid foundation to build upon, the Sierra 316’s mil-spec DNA means it’s compatible with a huge universe of aftermarket parts from brands like Magpul, BCM, and Geissele. It’s a simple answer to the question, “I need an AR that works.”
Pros & Cons
Pros: The biggest advantage is immediate functionality. You get a complete, shooting rifle that requires no gunsmithing. The chrome-lined barrel is a nice touch for durability at this price. Its standard configuration means endless customization potential. Finally, its availability at firearms-missouri.com for Missouri residents and nationwide makes it an accessible option.
Cons: You’re not getting ambidextrous controls or a free-float handguard, which are common on more expensive models. The trigger is a basic mil-spec unit—serviceable, but often the first thing enthusiasts upgrade. The carbine handguard can get warm during extended firing strings.
Frequently Asked Questions
Q: Is this rifle ready to shoot as soon as I pick it up from my FFL?
A: Yes, it is a complete, functional rifle. After completing the mandatory background check and FFL transfer required for firearm purchases, you just need to add ammunition and your preferred optic or iron sights to the rail. The included 30-round magazine means you’re range-ready immediately.
Q: Can I mount a sling and a forward grip on this model?
A: Absolutely. The standard carbine handguard has slots for attaching a sling swivel, and the bottom rail section is perfect for mounting a vertical foregrip or an angled handstop. It works with standard AR-15 lowers and accessories, so your options are nearly limitless.
Q: What’s the real difference between 5.56 and .223 for this rifle?
A: This barrel is chambered for both, which is crucial. You can safely fire .223 Remington and 5.56 NATO ammunition. The 5.56 chamber has slightly more headspace, and 5.56 ammo typically runs at higher pressures—so a 5.56-chambered rifle can shoot both, but a .223-only chamber should not shoot 5.56. This rifle gives you the flexibility to shoot whatever ammo you find.
