LA Capa Customs “S1” Reversible Thread Adapter for Hi Capa - Green Rainbow
The official LA Capa Customs thread adapters! The cap screws in two different ways for different looks.
11mm to 14mm thread adapter allows you to use a wider range of tracers and suppressors.
Supplied O-rings are for keeping the adapter in place, I would recommend loctite on the part that threads in to the outer barrel.
This is perfect for hiding longer inner barrels too if you run 6" ones.
