Proprietary single slot rail - JE Machine Tech Polymer Rail, M-LOK

This is not exactly what I had in mind for a rail section. I gave it 3 stars because it did actually fit into an M-LOK rail section, but the fastener was a disappointment. the hex head fasteners are much smaller than standard M-LOK components, making this product a proprietary rail section rather than an M-LOK rail section. It is quite easy to strip out the fasteners with even the specified 15 inch pounds of torque. So if you want to use this rail section for a bipod or if you will expect it to withstand anything more than very light forces, I would look elsewhere.
