Questions About This Deal
Is this a good price right now? +
Yes. At $579.99 this matches the lowest price we have recorded for it. Its 90-day average is $644.22. Set a price alert and we will email you if it drops.
How does this compare to other 5.56x45mm NATO ammo? +
It works out to $0.580 per round. The average across the 130 5.56x45mm NATO listings we track is $0.862 per round, and the cheapest credible listing is $0.480. Cost per round is the only fair way to compare ammunition, because pack sizes are not standardised.
How much does shipping add to the cost? +
Ammunition ships by ground and is priced by weight, so it matters. Work out the landed cost: add shipping to the box price, then divide by 1,000 rounds. A pack that is a dollar cheaper but ships for more is not cheaper.
How often is this price updated? +
We re-check every retailer daily and record a new entry whenever the price moves. We have 78 days of price history on this product and have logged 78 price changes in the last 90 days.
