    Great rail, most comfortable one I’ve ever felt. Great customer service from B. Kings Firearms too.

    Great item at a great price. Item was out of stock, so it was backordered. Received the item within 3 days of notification. Very please and satisfied with the transaction. Will be recommending to friends and family.

    Putting together an AR for the first time. It is all a fun learning experience. I, as most persons doing this kind of project, want and expect to end up with a high quality, accurate and awesome looking end result. I am on my way to being really pleased with the way my new firearm is looking. The Parallax hand guard and the Ballistic Advantage barrel from B. Kings Firearms are two major reasons for my success. They are quality great looking components that I was excited and very satisfied in purchasing from B. The price break for each I could not find anywhere I looked to be beaten–fantastic buys for sure. I can hardly wait to finish the arm to test its accuracy which I don’t have any reservations about being bang on.

    Many thanks–les.

    This is the slimmest and best looking freefloat rail there is. I have several of these on love them.

    Looks great with my 18” barrel. Very rigid and quality seems on point.

    Very nice rail at a great price compared to other online retailers. I haven’t gotten a chance to do anything rigorous with it yet, but I think it’s going to hold up well. The ergos are good with the rail sections for mounting whatever you could possibly imagine. The rail included the barrel nut, mounting hardware along with a shim kit. The only concern I have and I have no basis for; is there is nothing that aligns the rail to the upper, so only time will tell how the alignment maintains itself under more strenuous usage. All in all very satisfied, especially for the price which I got for $80 less than where I initially ran across the rail.

    Had a few small scratches or I would have given it a 5.

    Shipping was quick, and packaged well.
    Quality of forearm seems good. No tooling marks, nobparts missing, barrel nut screws onto upper receiver threads without issue. Compliments a 16 inch barrel well.
