The SB Tactical SBT5K solves the compact MP5K brace problem by integrating the folding mechanism directly into the polymer endplate designed specifically for two-pin K models. This brace works well for HK SP89 and SP5K builds where ultra-compact size matters, backpack guns requiring minimum length, and shooters who want authentic MP5K proportions with modern stabilization. What sets the SBT5K apart is the purpose-built design for 2-pin receivers at just 10.5″ length and 12.5 oz – it maintains the diminutive MP5K profile while adding QD sling capability and side-folding functionality.
Note: Requires 2 push pins for installation. Will NOT fit 1 push pin models. Gunsmith installation or fitting may be required due to varying tolerances between roller lock manufacturers. 9mm only.
