Hybrid AR-15 Receiver Crush Test

We first touched on Tennessee Arms Company's Hybrid AR-15 Lower Receiver in early October and they are due to start shipping initial orders this week in a variety of colors. They have now provided a video showing a vice crush test to show any potential deformity/breakage from stress on the magwell and trigger group compartment of the receiver. For a quick rehash, the Hybrid Receiver consists of a reinforced polymer material with Marine Grade Brass threaded inserts to attach the pistol grip and buffer tube. 

As with any polymer lower, we are curious as to the fit with other parts as well as the durability at those key connection points when put under stress. With their introductory pricing we are sure a fair amount of folks will be trying them out. Tennessee Arms Company will be releasing complete lowers as well. See their complete product lineup at
