Capital 3D have made our own K25 replacements called the Drop Bear springs which come with closed ends. This range will be expanding as well.
Over time we will stop importing the K25 from the USA due to the cost difference between the Drop Bear springs and importing.
Upgrade your homemade Nerf-style blaster with the K25 Main Spring imported straight from the USA, designed for enhanced performance and reliability.
- 5.5" (~140mm): Perfect for Talon Claw 4 and similar setups.
- 11" (~280mm): Full-length spring—cut yourself to your desired size for custom builds.
