The Fostech Echo Sport Trigger brings pull-and-release firing to the AR-15 platform without the premium price tag of the flagship Echo AR-II. The idea is simple but seriously fun at the range: one round fires when you pull the trigger, and a second round fires when you let it go. That kind of cadence puts a big grin on your face, and it keeps you in full control the whole time.
What sets the Sport apart from its bigger sibling is how you swap modes. Instead of using a third position on the safety selector, mode changes happen through a paddle mounted inside the trigger guard, just ahead of the trigger itself. It is a cleaner, less complex setup that a lot of folks find quicker to operate once they get a feel for it. The trigger runs three settings: Safe, Semi-Automatic where the gun fires on pull only, and Echo where you get the pull-and-release action.
Built from durable 4140 steel with a black finish for corrosion resistance, this trigger is made in the USA and designed to hold up to steady use. It fits standard mil-spec AR-15 lower receivers, so it drops into most builds without drama. One thing worth knowing up front: the Echo Sport does not include a bolt carrier group, and you will need a full-auto style M16-cut BCG for it to cycle correctly. Most current-production ARs already run one, but it is worth confirming before you order.
Installation is straightforward for anyone comfortable working inside a lower receiver, and Fostech offers video and written instructions to walk you through it. Folks who have run it report smooth function right out of the gate with hundreds of trouble-free rounds. If you are building a range toy or want to add some extra excitement to a rifle you already love, the Echo Sport delivers the goods at a price that leaves room in the budget for more ammo.
The Echo Sport delivers the same pull-and-release binary function as the Echo AR-II. The main difference is how you select Echo mode. Instead of using the safety selector, the Sport uses a paddle mounted inside the trigger guard. It is a simpler, more economical design that offers the same core performance.
Yes, you need a full-auto style M16-cut bolt carrier group for the Echo Sport to cycle and function properly. The trigger does not come with a BCG. The good news is that virtually all current-production AR-15s already run a full-auto profile carrier, so most builds are ready to go.
In Echo mode, your rifle fires one round when you pull the trigger and a second round when you release it. If your target moves after the first shot, you can move the selector to safe and the release shot will not fire. It gives you a fast cadence while keeping you in control the whole time.
The Echo Sport is designed to fit standard mil-spec AR-15 lower receivers, so it works with most common builds. It is intended for the AR-15 platform only and is not compatible with AR-10 or .308-style lowers. If you are handy inside a lower receiver, installation is a manageable job with the included instructions.
