Ok product, but no with standard "thin" headguards - MFT E-VolV Picatinny Rail 2.205" for Standard and Thickened Heat Shield

This product did not work "as is" with the thin heat shield on my Ruger AR-556 rifle. I had to add a rubber "shim" on the flat portion of the rail to take up slack so that the screws would tighten down. That's ok, and the product was usable, but buyers intending to use this rail on a think heat shield should be forewarned.

Otherwise the product worked as expected and was reasonably priced.
