Frequently Asked Questions
Armor Piercing Incendiary 5.56 Ammo for Sale
Is armor piercing 5.56 legal?
Federal law prohibits the manufacture or importation of armor-piercing ammunition under 18 U.S.C. § 922(a)(7), though possession may be legal federally. Legality also depends on specific construction and whether the round qualifies as armor-piercing under federal definitions. State and local laws vary, so check your jurisdiction's regulations.
Are there armor piercing 556 rounds?
Yes, armor-piercing 5.56 rounds exist. Examples include PMC's X-TAC Light Armor Piercing and SwissP's 5.56x45 AP TC. Federal law restricts manufacturing and importing armor-piercing handgun ammunition, and state laws vary. Check local regulations before purchasing.
What is the most lethal 5.56 round?
"Lethality" depends on context. The Mk262 Mod 1 77-grain open-tip match round is widely regarded as highly effective against soft tissue due to reliable fragmentation and yaw. For barrier penetration, M855A1 performs well. No single round is universally "most lethal" — terminal performance varies by target and range.
Can a 5.56 take down a deer?
Yes, 5.56 can take deer, though it's considered marginal. Shot placement and bullet selection are critical. Premium hunting rounds like Hornady work better than standard military ammo. Most hunters limit shots to 150-200 yards. Check local regulations, as some states prohibit 5.56 for deer hunting.
How much do 500 rounds of 556 cost?
500 rounds of 5.56 ammunition typically costs between $150 and $300, depending on brand and type. Brass-cased ammo runs around $0.51–$0.54 per round, with premium loads costing more. Buying in bulk usually lowers the per-round price.
What is the military replacing 556 with?
The U.S. Army's Next Generation Squad Weapon program selected the 6.8x51mm cartridge to replace 5.56mm for infantry rifles and automatic rifles. The XM5 rifle and XM250 automatic rifle chamber this round. Full military-wide adoption is ongoing, with initial fielding to select units.
Why don't gun ranges allow green tip ammo?
Most ranges ban M855 green tip ammunition because its steel-core penetrator damages steel targets, bullet traps, and backstops far faster than standard lead-core rounds. Ranges enforce no-steel-core policies to control repair costs and liability. This is a facility equipment concern, not a legal restriction.
Why doesn't Walmart sell 556?
Walmart stopped selling 5.56 ammunition in 2019 as part of a broader policy change following several mass shootings that year. The company discontinued all short-barrel rifle ammunition at that time. Other retailers still carry it; we currently track 15 vendors with 5.56 in stock.
