Just put this on my SW Sport 2 and I love it! Very easy to put on and its light!

ProMag Quad rail

This was exactly what I was looking for. Perfect fit for my Bushmaster. Gives me plenty of accessory mounting options. Thanks AT3.

Thanks for sharing your feedback, Robert. We're glad you're satisfied with your purchase. Cheers!
Good Quality, low price

Although this is not metal, this product is made of a hardened plastic with an aluminum cover on the inside that helps to defuse the heat away from the plastic. My friends have real picatinny rails that are metal and $150 and they have stated that the rail I use is just as good. As for the company service, I will be purchasing off of them again due to the timely delivery and low cost for products at a great quality.

Thanks for sharing your feedback, Billy. We're glad you're satisfied with your purchase. Cheers!
