Description
Reduced weight safety selector spring for the Springfield Kuna. This spring will reduce the safety selector operation weight by approximately 15% with respect to the factory Kuna spring. We tested many different spring rates/designs in the Kuna selector assembly and found this to be the sweet spot for firm tactile operation without being overly stiff or difficult to use. This spring is a drop in replacement for the factory spring and can be used with the original selectors, or paired up with any combination of our machined selectors for the Kuna. Our springs are manufactured from stainless spring steel for smooth operation and a lifetime of corrosion resistance and maintenance free service.

Easy to install.Such an improvement for 5 bucks. I have arthritis in my thumbs and the stock safety spring was so painful to operate. I have been using HBI products for years and was never let down.

Combine this with the safety offered by HBI, and you will not be disappointed. MUCH easier to get in and out of safety. Easy thumb flicks are all it takes. Installation is easy; (@thegunchannel) has a great video outlining the installation for the regular person.

A must upgrade for Kuna, must better and work best with their thumb selector.

This spring makes a night and day difference on the safety selector, so much easier now.

It’s impressive how much improvement comes from such a small spring. I’m now able to move between safe and fire comfortably using the same hand and thumb. The lever is much smoother and easier to operate.

Wowsa, wowsa, wowsa! I’m dancing for 1,000 hours! (anyone get the obscure reference?) Either way, get one of these beauties right away. It makes all the difference and should be an immediate upgrade. Grab a set of safety selectors while you’re at it.

The stock selector was stiff. You could always cut the stock spring down, but for the price I figured why not grab this and have the stock spring on hand as a spare. The difference is immediately noticable. It’s well worth it.
