Frequently Asked Questions

5.56 polymer stripper clips hold 10 rounds of 5.56 NATO or .223 Remington ammunition in a single stack for fast AR-15 magazine loading. SCUSA polymer clips weigh ~3g each — 4× lighter than USGI steel — and feature the patent-pending Color-Coded Ammo ID™ System for instant load identification.
Olive Drab = M855 green-tip (long range, steel core). Black = M193 duty and defensive loads. Range Orange = M193 training and range ammo. One color per load type — no more guessing which clip has which round.
SCUSA polymer clips are compatible with the Maglula® StripLULA® Gen II loader and similar polymer-compatible speed loaders. Do NOT use metal stripper clip guides — metal guides will damage the polymer clip.
Approximately 1,400 rounds of 5.56 NATO on standard 10-round SCUSA stripper clips stacked in aligned rows — vs approximately 1,000 rounds loose. That's 40% more rounds in the same container.
Yes — 5.56 NATO and .223 Remington share the same case dimensions. SCUSA polymer clips work with all standard brass-cased 5.56 and .223 ammunition including M855, M193, and commercial loads.
