HBI Short Stroke Buffer Kit for your Springfield Kuna. Our short stroke buffer kit is a drop in replacement for the factory buffer pad and recoil spring. The increased length of the HBI buffer shortens the rearward bolt travel, lightning the recoil impulse and reducing possibility of spent cases becoming lodged in the receiver. When paired up with the +20% recoil spring our Short Stroke Kit is a simple, engineered solution that will always run when you need it.

Please Note: Our Short Stroke Buffer kit includes and is specifically designed for use with our +20% recoil spring. By reducing the rearward travel of the bolt we also reduce the amount of energy stored in the factory spring, which is used to return the bolt into battery with every shot. Our Short Stroke Buffer will run using the factory spring, but recoil impulse/timing will be more abrupt and your bolt will have less energy available to drive the next round into battery.

FRT/Super Safety/Aftermarket Lowers: We can guarantee that our buffer kit will be 100% reliable with every Kuna as it leaves the HS Produkt/Springfield Armory factory. However, due to a VERY large range in aftermarket fire control group options and even aftermarket lower receivers and even magazine swaps available for the Kuna we are unable to confirm compatibility with every combination of aftermarket parts available now, and into the future. Our Kuna short stroke kits have been used successfully with many combinations of aftermarket parts, but ultimately it is up to the end user to determine if our buffer kit is compatible with anything other than factory (OEM or HBI) parts.
