Well put together rail section

by -

Perfect for what it is. Attached solidly and quickly. Still waiting for the piece to attach to it, but perfectly fine machining with no sharp edges or odd marks

Best bang for the buck aluminum m-lok sections.

by -

I needed 3 sections of m-lok rail for 3 different guns and due to their use on suppressed guns I needed them to be aluminum to withstand the heat. I found these and couldn't believe the price compared to the big name brands plus they are made in U.S.A. I am extremely happy with the quality and all my attachments fit exactly as expected so they are sized to spec. These EXPO Arms m-lok sections will be the only brand I buy going forward.

It's an aluminum section of picatinny rail

by -

What can you say? It's properly made section of M-LOK picatinny rail. It's metal and not plastic of questionable quality. You can mess up machining metal, but this ain't it. It's doing it's job and it's cheaper and in stock compared to the OTHER main brand.

Easy Mount Pic Rails
