We think that this is one of the finest and most practical items in the firearms industry. By purchasing a Complete Fostech Echo Sport Lower, you can utilize virtually any AR-15 upper already in your possession and try out the fascinating world of binary trigger shooting in any combo of your choice. The receiver is multi-caliber so as long as the caliber your shooting feeds from standard AR-15 .223 / 5.56 based mags, you should be good to go. The receiver is fully assembled so all you should have to do is drop on a compatible upper and push the pins and you are ready to rock and roll in seconds. Note, the Echo Sport requires a Mil-Spec bolt carrier group which is common to approximately 95% of all AR-15 models on the commercial market.
A word about the " Blems" ... Whenever Fostech offers something under a Blem Sku it means that they have found a visible cosmetic imperfection during their inspection process. In all cases, the blemish will be cosmetic in nature only with the mechanics and function of the item still at 100% and all factory warranties will still apply. However, if this concerns you then the ultra-safe thing to do is don't buy it. Our experience has taught us that there are some people that will search over something like this with a magnifying glass until they think they spot the blem, and then it will keep them up at night because... well some folks are just like that. However, the reality is that the folks at Fostech are simply hyper-critical when it comes to their product and they will segregate an item and call even the slighted imperfection, that most companies would release as a first-run item all day long, a blem. In fact, they will sometimes separate out the entire lot over just a few pieces where they have spotted a minor cosmetic imperfection in the bunch. When we are able to discern what they are calling a blemish it is typically a small run in the cerakote due to overspray in a certain area on the receiver, and this area could even be... and in many cases is... an internal surface, where it can't be seen to start with. We have also seen them call perfect finishes "Blems", due to minor color differences between the shade of color that their color chart calls for, and what the end product resulted in. For example a Stealth Black, as opposed to a Midnight Black. Heck, black is black to me and industry standards in regards to shades in color vary wildly so I wouldn't ever consider this alone to be a blem, but hey, Fostech's attention to detail is what makes their products so desirable so if they want to offer Blem pricing on something so close to perfect, then we will be proud to pass it along.
About the Echo Sport Trigger - The Echo Sport Trigger from Fostech provides the same pull-and-release firing functionality of the original Fostech Echo AR-II Trigger, but the controls have been modified to eliminate the use of the 3rd safety selector position. Instead, a control paddle in front of the trigger guard moves side to side to select single fire or Echo firing modes. Same functionality, but at a significantly lower price! The Echo Sport Trigger allows the shooter to select from 3 different settings: Safe Mode: Firearm will not fire. - Semi-Automatic Mode: Firearm fires when the trigger is pulled. - Echo Mode: Firearm fires when the trigger is pulled and also when the trigger is released.
The Echo Sport is different from Fostech’s Echo AR-II in that there’s an added paddle switch in front of the trigger to change firing modes from binary to standard semi-automatic firing instead of using the safety selector like the original Echo trigger. When the shooter is in the Echo Mode and depresses the trigger firing one round, the shooter can move the paddle to the semi position while firmly holding the trigger rearward and a second-round will not fire upon release.
Patent Pending new ATF Approved design. Not a single drop-in assembly like the original, the Sport functions with any full-auto style bolt carrier.
Note - This product ships with no magazine. This receiver cannot ship to California, the District of Columbia, Iowa, New Jersey, New York, Hawaii, Rhode Island, Flordia, Maryland, Connecticut, Washington, Oregon, Massachusetts.
