After almost 1.5 years in the making, I've finally finished my grail gun: an HK MP5SD (remarked and everything). The conversion was done by Dakota Tactical. It started out life as an HK SP5.
It's pictured here in SBR form with a B&T side folder, HK Parts 4 pattern pictogram, Broad River Tactical SD adapter and a CAT MOB. The BRT adapter allows you to connect a normal suppressor to the M18x1 thread pattern on the SD barrel. With the MOB, this is by far the QUIETEST 9mm out there. I shot it with regular 124 grain side by side with my SP5K using 150 grain subs and an Obsidian 9 and it wasn't even close.
The king of SD's reigns supreme!
