HB Industries® +20% Recoil Spring for Springfield Kuna

The HB Industries +20% Recoil Spring for the Springfield Kuna is designed to increase recoil spring rate and fine-tune the operation of the firearm's recoil system. Compared to the factory spring, it provides approximately 20% greater spring force, helping adjust slide velocity and cycling characteristics. It is a direct replacement for the factory recoil spring and requires no permanent modifications.

20% Increased Spring Rate

The spring delivers approximately 20% more resistance than the factory recoil spring, slowing rearward slide movement and altering the timing of the operating cycle. Depending on the firearm configuration, ammunition, and muzzle device, this can help optimize cycling characteristics and overall handling.

Fine-Tune Recoil Performance

A properly matched recoil spring can reduce the abrupt rearward impact of the slide and contribute to a smoother recoil impulse. The final result depends on the ammunition and other components installed, so a higher spring rate may not be suitable for every setup.

Compatible with Factory or HBI Buffer

The spring is intended to work with the HB Industries Short Stroke Buffer, creating a matched recoil system. It can also be installed with the factory Springfield Kuna buffer if you only want to modify recoil spring characteristics without changing the rest of the recoil assembly.

Direct Drop-In Replacement

The spring installs in place of the factory recoil spring without requiring permanent modifications to the firearm. It is suitable for shooters looking to fine-tune the recoil system for their preferred ammunition or accessory configuration.
