The Geissele S3G trigger installs in your lower receiver in the same way that a Mil-Spec trigger is installed. It uses a standard .154” trigger and hammer pin so it will fit in any Mil-Spec stripped lower receiver. It features a curved trigger bow that gives you optimum trigger control and ergonomics. Not only does it work in 5.56 or .223 AR-15 rifles, but it also works in .308 AR-10 pattern rifles. Each trigger is precision EDM wire cut from heavy-duty tool steel with a durable black finish giving you the reliability and durability you can depend on.
