Geissele AR15 Super Dynamic - 3 Gun Trigger

Geissele AR15 Super Dynamic - 3 Gun Trigger

The Geissele Super Dynamic-3 Gun Trigger is based on the Geissele Super 3 Gun (S3G) trigger. Like the S3G, the SD-3G features a shortened length of pull and a very rapid reset that give it a unique, hybrid trigger pull that is a cross between a traditional two-stage and single-stage trigger while still retaining the safety and durability of a two-stage combat trigger.. The SD-3G incorporates a flat trigger bow that is patterned after the flat triggers of the M1911 pistol. This allows for a perceived lighter pull weight and improves tactile feedback to the user. Constructed from precision-machined tool steel, the Super Dynamic-3 Gun Trigger maximizes trigger speed so that rounds can be sent downrange as quickly as possible while still remaining accurate making it an excellent option for 3 Gun competition shooting.
