New, improved design, more durable material, precision wire-formed production, updated strength specification for more efficient operation.
We see this part snapping due to wear occasionally, but more often we see them getting over-stretched and bent by users due to incorrect assembly/disassembly of their guns, so we decided to make some aftermarket replacements available.
Provides a pull strength of 230g for a 50mm extension, compared to 145g pull strength of standard spring. Previous design was around 375g.
This new design also uses a thicker stainless steel wire to increase durability, while diameter was increased to balance the increase in strength from the thicker wire.
