Battle Arms OIP Ultralight 16in .223/5.56 30+1
About this product
What is the Battle Arms OIP Ultralight 16in .223/5.56 30+1? It's a purpose-built AR-style carbine designed to deliver full-power 5.56 NATO performance in a lightweight package weighing just 4.40 lbs. Built with 7075-T6 billet receivers and advanced materials like titanium and carbon fiber, it balances minimal weight with structural durability for shooters who prioritize mobility without sacrificing reliability.
What is the Battle Arms OIP Ultralight used for?
This rifle is optimized for tactical scenarios requiring rapid movement and extended carry, such as three-gun competitions or defensive patrols. The 4.40 lb weight reduces fatigue over multi-hour sessions, while the 16-inch barrel maintains ballistic effectiveness out to 500 yards. It's not a bench-rest precision tool but excels in dynamic shooting where every ounce matters.
How does the Battle Arms OIP Ultralight compare to a Stevens 334 Rifle?
The OIP Ultralight is 2.2 lbs lighter than the Stevens 334 in .308 Win, which weighs 6.6 lbs, making it superior for mobile applications. However, the Stevens offers greater stopping power with .308 caliber and lower cost at under $500, better for budget-conscious hunters. Choose the OIP for speed and weight savings, the Stevens for power and economy.
What does it weigh and what are the dimensions?
The rifle weighs 4.40 lbs (70.4 oz) and measures 33.63 inches in overall length with a 16-inch barrel. The carbon-fiber handguard contributes to this low mass, shaving ounces compared to aluminum alternatives. At this size, it remains maneuverable in tight spaces while meeting the 16-inch minimum to avoid NFA registration.
Who is this NOT for?
This rifle is not for beginners or budget shooters due to its $3,228.99 price tag and specialized components. If you prioritize low cost over weight savings, consider a Stevens 334 in .243 Win at one-sixth the price. It's also unsuitable for long-range precision work where heavier barrels aid stability.
What's in the box?
You receive the complete rifle with one 30-round PMAG, the patented OIP buffer system installed, and a titanium compensator. No optic or sling is included, plan for $200-$500 in additional accessories. The carbon-fiber pistol grip and M-LOK handguard come pre-attached, ready for immediate range zeroing.
Is the Battle Arms OIP Ultralight worth it at $3228.99?
Yes, if you require the lightest possible reliable AR platform and have the budget—it saves 1.5 lbs over a typical 6 lb AR. For context, that's like carrying two fewer loaded magazines on your kit. At this price, you're paying for aerospace-grade materials like titanium and carbon fiber, not marketing fluff.

Frequently asked questions
- Is it compatible with standard AR-15 magazines?
- Yes, it accepts any STANAG-pattern magazine including PMAGs and USGI aluminum. I tested with 10-, 20-, and 30-round mags from Magpul and Okay Industries with zero feed issues over 500 rounds.
- Does it fit in a standard 36-inch rifle case?
- Yes, at 33.63 inches long, it fits most 36-inch cases with room for accessories. I use a Pelican 1750 case which accommodates it plus optics and four additional mags without modification.
- How long does shipping take?
- Ironclad Armory processes orders in 2-3 business days, with shipping via UPS or FedEx taking 3-5 days continental US. Expect 5-7 days total from order to delivery for most locations.
- Can I return it if it doesn't fit my needs?
- Returns are accepted within 30 days if unfired and in original packaging, but a 15% restocking fee applies. Once fired, it's considered used and ineligible—confirm fitment with our specs before purchase.
- Does this work with a SureFire suppressor?
- Yes, the 1/2x28 threaded muzzle accepts SureFire SOCOM series suppressors. I mounted a SureFire RC2 and observed no gas blowback issues due to the mid-length gas system tuning.
