Broad River Tactical - CAR-15 SD Hub Adapter Bravo (1.375x24)

We are proud to finally offer our SD Hub adapter, which converts your standard suppressor into a SD suppressor. The adapter acts as the expansion chamber in a SD style suppressor for the barrel ports to  bleed gas into. The barrel is completely inside the adapter so it adds over 4" of expansion chamber without adding overall length. We are offering these in three hub thread sizes, Alpha, Bravo and P-Series (Wolfman). We may consider more options, if there's enough interest. These adapters were designed for our 9mm SD uppers but can also be used with other SD platforms with m18x1 threaded barrels. If using on the MP5SD, you'll need the enhanced cocking tube support as the adapter is 1.625" OD. We are also planning to add other calibers to the SD line that can take advantage of this adapter for maximum suppression. These adapters are Grade 5 Titanium with a 17-4 Stainless adapter end.
