The fore end is a Samson Evolution 9"

Because the whole unit dose not attach directly on to the AR barrel nut, they can sell their products without a export licence, you know the one that stops items over $100 being shipped.
They include everything needed including the 2 Allen keys/wrenches, including the thermal bushing which is fitted onto the barrel nut, which in turn the hand guard is fitted to.
If you have ever handled a fore end with 4 rails running all the way down, you will know how uncomfortable they can be, even capable of cutting fingers. The solution is to put the protectors/covers over the top but you end up with something quite chunky and personally speaking I did not like.
This tube only has a rail running along the entire top, which was the same hight as the one on the SGC lever action - as can be seen by the scope being mounted half on one and half on the other.
It comes with two 2" rails and one 4" rail but I am sure that more can be sourced should you need them. Due to the S shaped fixing holes, the rails can be fitted at dozens of different angles around the grip and you are not limited to the 4 of a quad rail. I have mounted one at 45 degrees on the front as I intend to put a small red dot sight up front for close targets.
For my hands, and I think Ovenpaas' we found the diameter of this tube to our liking, the finish is spot on and in case you can't tell I can not recommend it highly enough.
I want to source a flash muzzle break to finish the front end off, some are available but as this is purely cosmetic I will be looking to pay as little as possible, there is of course the option of a moderator but it would have to be very light,
