The Cross Armory CRFSPP Flop Stop Pin Pal is a small-footprint take-down pin retention tool built for AR platform rifle builders and shooters who want to keep their hardware where it belongs. If you've ever had a detent spring launch across the workbench—or worse, lose a pin during assembly or field stripping—this melonite steel accessory is a practical fix. It's designed to catch and hold pins in place, making AR takedown less of a frustrating treasure hunt and more like an actual procedure you can repeat without losing parts.
Built from melonite steel, the Pin Pal offers durable corrosion resistance and reliable retention whether you're a gunsmith prepping rifles, a shooter who breaks down their rifle regularly, or just someone building their first AR and wants assembly to go smoothly. The black melonite finish matches modern AR aesthetics and holds up to repeated handling.
Cross Armory built this for ARs, so it integrates with standard platform take-down points and detent systems. It's a straightforward solution to a small but real problem—the kind of thoughtful detail that separates a good build day from an afternoon spent fishing for springs on the floor.

Melonite is a case-hardening process that creates a corrosion-resistant, durable surface on steel. It resists rust and wear from repeated handling during assembly and disassembly.
The Pin Pal helps during AR assembly, break-down, and maintenance by catching and holding take-down pins and their detent springs so you don't lose them on the floor or bench.
