LR 308 is a trademark of DPMS, so going by that, I would say the odds are very high that the product you posted the link for are DPMS compatible. More .308 AR type products are compatible with DPMS than any other configuration. Up until about 5 years ago, almost all .308 manufacturers were proprietary in fit(or so they claimed), so it was really hard to get accessories, and you just about had to get your parts from the manufacturer. Then some folks who had some money started doing side by side comparisons, and found out that some manufacturers had been using DPMS specs for some time, and then the market started opening up. I think at one time in the future, everyone will settle on one format, sorta like when the VCR's were the craze and everyone went to VHS and BETA went down the tubes. I believe there are about 5 different formats for .308's- DPMS, Armalite, Rock River Arms, Bushmaster. If you want another source of DPMS compatible .308 parts, Aero Precision has them.
