Choke AdapterWe have taken our popular Saiga 12ga 10 Slot Flash Hider and threaded it internally to accept "Winchester" chokes. The flash hider ships with a DPH Arms Full Choke that has been percision machined from 17-4 stainless steel. 17-4 SS was chosen for its very high anti corrosion properties. The flash hider has been hardened to maintain the integrity of the threads inside. Although the threads are hardened we cannot guarantee the threads from being damaged over time. - See more at:
