What to Look for When Buying Cheap 5.56 Ammo Without Sacrificing Reliability
Cheap refers to price, not quality; budget 5.56 from reputable manufacturers still meets SAAMI pressure specs and runs reliably, making it a smart pick for high-volume range days.
Keep these specs in mind when comparing options:
- Grain weight: 55gr FMJ is the most common and least expensive, great for drills and high-volume shooting. 62gr (like M855) has a slightly better ballistic coefficient but costs more.
- Bullet construction: FMJ and FMJBT both handle training well; FMJBT holds a straighter path at distance.
- Brass vs. steel casing: Brass costs more upfront but can be reloaded, lowering cost over time. Steel is cheaper per box but not reloadable; the right fit depends on your volume and whether you reload.
Buying in bulk brings your per-round price down fastest — multi-box deals and free-shipping thresholds add up, so the more you stock up now, the less you pay per trigger pull later.
One thing to check: 5.56 NATO runs at higher pressure than .223 Rem. Confirm your chamber marking first; 5.56 or 5.56 NATO-marked rifles are good to go. .223 Wylde handles both, but never fire 5.56 NATO in a .223-only chamber.
Use Able Ammo's filters to sort by manufacturer, price, and quantity, and find in-stock cheap 5.56 that matches your platform and budget.
FAQs
Is cheap 5.56 ammo actually reliable, or will it cause feeding issues in my AR-15?
Budget 5.56 from name-brand manufacturers is built to spec and cycles reliably for consistent performance in high-round-count sessions.
How much should I expect to pay per round for cheap 5.56 ammo?
Competitive budget FMJ runs roughly 40–50 cents per round, with bulk orders pushing that cost even lower.
What's the difference between 55gr and 62gr for range use?
55gr FMJ is the go-to for volume training, available and cheapest. 62gr costs more with a slightly better ballistic coefficient.
Can I reload brass-cased cheap 5.56 ammo?
Yes, brass can be reloaded multiple times, cutting long-term cost per round. Steel is cheaper upfront but can't be reloaded.
Will cheap 5.56 NATO ammo work safely in a .223 Rem chamber?
No, check your chamber marking first. 5.56 NATO runs higher pressure, so only fire it in 5.56 or .223 Wylde-marked rifles.
