Pre-order item / not available for immediate shipping

This is an MP5SD, ( integrally suppressed ) 9mm parts kit build in semi-auto, using original HK parts, RCM barrel, and the LSC/PTR receiver flat kit. The build was done by Black Ops Defense to our highest quality standard!

The demilled MP5 machinegun parts were refurbished and reused to build this all HK parts ( RCM barrel ), semi-auto version of the HK MP5 SD. ( Similar to the HK SP5/94, MP5SD conversion )

Shown in possible SBR configuration. This would be considered a short barreled rifle and separate suppressor, requiring 2 sets of NFA paperwork and 2 tax stamps. ( Pistol and rifle configurations also available )


Some images show possible configurations with and without barrel extensions, custom engraving, accessories, etc… ( optics and other unmentioned accessories not included )
