I called the other day and was told you don't stock this product. This might be something you may want to carry. Most places only catalogue the #38, which is much more expensive. For those of us with a really beefy scope on their AR's, the #36 rail fixes the eye relief problem, and is probably more available than the FIRE rail. The Super Extended is probably the way to go, since you can just adjust your eye relief, then cut off all the excess and reblue the end.
