Fostech 6100-TUN-4140: Build the rifle of your dreams with this Fostech lower receiver. This receiver is made with Forstech's proprietary LITE material, making it 30% lighter than traditional aluminum receivers, and it is just as strong. Fostech fits this receiver with an MFT Minimalist Stock and their own Fostech Saber grip. The main feature of the receiver is, of course, the ECHO Sport binary trigger that comes installed. This trigger is amazing, to say the least. Three settings are safe, semi, and binary, which allows the gun to fire with every pull and release of the trigger. The speed at which you can send lead downrange is astonishing. This fantastic receiver is ready to be mounted with any AR-15 type upper receiver. 
The Echo Sport is an economic binary pull and release trigger for the AR-15 Platform. The Echo Sport has the functionality of the Echo AR-II. The only difference is that you select the echo mode from a paddle rather than the safety sector. The Echo Sport is designed to function in the AR-15 Platform. The Echo Sport gives you all the functionality of the original AR-II at a more affordable price. In addition, it is more efficient, less complex, and, most importantly, less money.
Note - Fostech is listing these under a Blem SKU meaning that they will have a very minor cosmetic blemish of some kind that will in no way affect the function of the product. In our experience, this typically amounts to a minor run in the cerakote or a slightly different color variation than the norm. In most cases, we can not see why they are called blems. They ( Fostech ) have even told us that the blem in the finish could be hidden away due to it being on the internal surface of the receiver.
