The Kalashnikov USA Triangle Side Folding Brace is designed to transform your KP9 in form and function to the original Vityaz style triangle side-folder. The KUSA triangle brace latches to the receiver when folded by use of the integrated hitch. This is a close as you can get to the original SBR without the tax stamp and waiting period.
