Description
Direct fit SBT arm brace for your Springfield Kuna. Our low profile aluminum adapter integrates the SBT HK or CZ type arm brace directly into the receiver of your Kuna Pistol. The assembly will maintain the side folding characteristics stock/brace. Our brace adapter is machined from billet 6061T6 aluminum and hard coat anodized to MIL-A-8625, the SBT braces are polymer/elastomeric.
Choose from the drop down menu above to order either the SBT HK type brace or the SBT CZ type brace. Both are great options for the Kuna and images of both are available in the gallery for reference.
If you are looking for a true MP5 stock integration (SBR), we offer that as well here: HK MP5 Stock Retrofit kit.
Note: Due to typical production tolerances in the Kuna receiver geometry, your rear takedown pin could fit more tightly with our adapter than with the factory adapter. The factory adapters are polymer, which is a more flexible material, and can account for a wider range of hole locations. Our adapters are aluminum, which is a more rigid material, and therefore have a smaller range in which the takedown pin can be a true “slip fit”. Because of this, we designed our mating geometry to favor the tight side of the tolerance zone, guaranteeing that our adapters will always fall between a slip-fit and tight-fit condition; never too loose. Ultimately, and depending on your receiver, you might need to use a rubber mallet or punch to install/remove your rear takedown pin (nothing more). We believe the risk of being tighter and potentially needing a punch to better than the possibility of your adapter fitting loosely/wobble with a stock/brace attached.
