5.56×45 NATO Bullet Keyring | Real Bullet Keychain

The Plain 5.56 NATO Keyring

This is our standard 5.56×45 NATO keyring – no engraving, just the round. Each one starts as a once-fired brass case, cleaned and polished, resized to full length and fitted with a seated bullet, then finished with a 25mm split ring.

The 5.56×45 NATO

NATO standardised the 5.56x45mm in 1980, after trials that settled on FN’s SS109 bullet. It grew out of the .223 Remington used in the early M16, and today it is fired by the British SA80 family and AR-15 and M16-pattern rifles around the world.

Which 5.56 Keyring?

• Plain 5.56×45 NATO – this listing
• Fired 5.56 blank keyring – a real blank with its crimped end and no bullet
• “Light but lethal”, “Standard issue” and “Suppress the Threat” – engraved designs
• .223 Remington keyring – the civilian round it grew from

FAQ

Q: Is it a real 5.56 round? Yes – a genuine once-fired 5.56x45mm NATO brass case with a seated bullet. Not a replica.

Q: Is 5.56 the same as .223? Closely related but not identical – the 5.56 NATO runs at higher pressure and the chambers differ slightly.

Q: Is it safe to carry? Yes. It is fully inert and legal to own and carry in the UK without a licence. Always check with your airline before travelling abroad with this item.

Q: Can it be engraved? Yes – see our laser engraving page, or choose one of our engraved 5.56 designs.

Q: How big is it? About 57 mm long – see the Additional information tab for full specifications.

Q: Does it make a good gift? For a serving soldier, veteran or AR shooter, yes. Our gift box is available separately.
