.223/5.56 Ammo — In Stock in Canada

Sep 6, 2026, 10:12 a.m.

.223 Remington and 5.56x45mm NATO are dimensionally near-identical and are frequently sold, and shot, interchangeably — though 5.56 NATO runs slightly higher chamber pressure, and most modern rifles rated for 5.56 will safely run either. This is the standard chambering for the AR-15 platform and its many Canadian-compliant derivatives, which puts it among the highest-volume centerfire rifle cartridges we sell. Bulk case pricing (typically 500 or 1,000 rounds) usually gives the best price per round for range and practice ammunition, while lighter-weight boxes in 55gr or 62gr loads are common for general-purpose shooting. Because many AR-15-pattern rifles and their variants are subject to specific federal classification rules in Canada, always confirm your particular rifle's classification before buying — the ammunition itself carries no restriction beyond the standard PAL/RPAL verification every firearms and ammunition order requires. This board tracks live stock and price per round across our full .223/5.56 range so the cheapest available option is always the top row.
