Do NOT use with metal stripper clip guides — metal guides will damage the clip. Use polymer speed loaders only.
Common questions
SCUSA polymer stripper clips are built for 5.56×45mm NATO / .223 Remington and feed standard AR-15 magazines using a compatible speed loader.
For the fastest loading, yes. SCUSA clips are fully compatible with the Maglula® StripLULA® Gen II (sold separately). You can also stage rounds with the SLB™ loading block.
No. All clips and kits ship empty. Ammunition is not included and is not sold by SCUSA.
SCUSA polymer clips are lighter than USGI steel and won’t rust or corrode, which makes them ideal for range use and long-term sealed storage.
Use the builder above to compare options — start with clips, then add a loading block, speed loader, ammo can, or desiccant based on how you load and store. The builder shows kit pricing side by side.
In-stock orders ship in 1–2 business days from Texas, and orders over $48 ship free. Return unused items within 30 days for a full refund.
