Purchased above mentioned item for a DPMS LR-308 outfitted with an 18 inch bull barrel and Leupold optics. Easily mounted sling attachment, BUS, and bipod to the rail. I will purchase for other builds should the occasion call for it. I would recommend this product.
Pros: Sturdy, sexy aesthetics, versatile, comfortable, affordable priced, easy to install/modify
Cons: Most module parts are sold separately and can be pricey. Also, these rails (for 308) sell so fast they are sometimes on back order for a while. I know mine was.
