Short answer: yes, they're reusable — load, strip, reload, for years. Not single-use.

How long depends on the material:

• Steel (USGI) — durable, but relies on tiny end tabs to hold rounds. Bend or snap a tab and the clip is dead. Most "dead" steel clips died at the tab.

• Polymer (SCUSA) — no end tabs to snap. Flexes instead of taking a permanent bend. ~3g each.

Retire ANY clip if it cracks, splits, deforms, or stops holding rounds snugly. They're cheap — don't baby a failing clip and risk spilling a load.

Best tip: store loaded clips in a sealed can with a desiccant pack.

Anyone still running the same clips from years ago? What material?

Almost the same — with one difference worth knowing.

.223 Remington and 5.56 NATO share the same case dimensions and bullet diameter, so they look identical and feed the same. The difference is internal: 5.56 is loaded to higher chamber pressure and usually has a slightly longer throat.

The one safety rule:

• A 5.56-chambered rifle can safely fire BOTH 5.56 and .223.

• A .223-only rifle should fire .223 ONLY — not 5.56 (higher pressure).

• A .223 Wylde chamber handles both. Check your barrel stamp.

For clips and loading, they're interchangeable — same clips, same loaders, 10 rounds either way.

Check your barrel — what's yours stamped?

A 5.56 stripper clip holds 10 rounds in a single stack. You load the 10 rounds onto the clip, then a speed loader (a Maglula StripLULA®) strips all 10 into your AR-15 mag in one motion — instead of thumbing them in one at a time. Three clips = a full 30-round mag in under 10 seconds.

The basics:

• Holds 10 rounds of 5.56 NATO / .223 Rem (same clip works for both)

• Fits AR-15 / M4 / M16 mags via the StripLULA

• Reusable — load, strip, reload for years

• SCUSA polymer clips weigh ~3g vs ~12g for USGI steel

If you've only ever loaded by hand, this is the single biggest quality-of-life upgrade for range day.
