As soon as I pulled this launch rail from the box I could tell it was a high quality unit! Fifteen minutes and it was together. I can’t wait to get it out to the field and give it a trial by fire. A tip for putting the two sections of rail together, put the connector on the two sections loosely. Put the assembly on a flat surface like a coffee table, a counter or dinning table then slowly draw up the allen screws evenly while a helper puts pressure on the connector this will make the two rails strait and even. If they aren’t even then do it again you’ll get it! Have fun!
