    There's more to the extended forend that just being able to blaze like Chris Costa. The extended rail allows for additional mounting options. This is nice when mounting a flashlight since you can mount the light closer to the muzzle so the light doesn't cast a big shadow. Also, the longer rail allows for mounting slings and lights without giving up space that would otherwise be needed for the support hand.

    I also like a longer forend for carrying the rifle in a patrol-type fashion. If you've ever walked a good distance with a little weight on your back, you know it's nice to be able to move your arms around a little once the straps on your ruck start biting into your shoulders and making your arms go to sleep. The old A2 long handguards were good for this since they allowed you to move your support arm to a more comfortable spot while still maintaining the rifle in a ready position.
    That 7" looks real sweet. One of the many reasons I went with the SIG516 was the fact that SIG would actually sell me the 7", 10", or 14.5" SIG516 Uppers. Try doing that with the HK MR556, FN SCAR, or Rurger SR556 if your non-military or non-law enforcement.

    Good point. The other companies you mention are ignoring a small but growing NFA/SBR market.

    Dontcome2myhouse,

    What did it run you, if you don't mind my asking. I went to PSA's site and they're out of stock. I am just wondering if the FDE edition is a premium price compared to the black.

    It was $1450. I don't think there was much of a price difference b/t the black and FDE. I do know if you ordered the FDE you would be getting the Gen2 like mine. If you got the black it could be either Gen1 or Gen2.

    What light would you recommend for this rifle?

    There are a bunch of good choices.

    You might want to try something like this:

I'm pretty sure I read somewhere that Cerakote is applied OVER the hardcoat anodized finish. The FDE finish is also on the INSIDE of both the lower and upper receivers as well. I like this as it helps me see any fouling/grime with ease. There is zero play b/t the upper and lower receivers, but this aided by the rubber thingy in the lower that creates tension b/t the two halves. The tension is so tight that I can't remove the rear take-down pin without using the tip if something (like a bullet) it push it through so I can grab the other side.
    Hate to sound like a broken record, but do you have any pics of the interior of the receivers?

    Also, is it an accuwedge between the halves that you're referring to? Or is it something SIG made? This is looking like a really nice rifle, I haven't found one at a local shop yet to handle it.

    It's something SIG made that does the same exact job as an accuwedge. It's not removable. I'll get some pictures.

    Thanks. Do you like pressure pads (either attached to the rail or vertical grip) with the wire attached to the flashlight tailcap or do you prefer to just activate the light by pressing the tailcap with your finger or thumb?

    A pressure pad attached to the top rail is nice if you want something that will allow you to easily activate the light with either hand.

    With that said, I'm currently running a Gear Sector light mount and tail switch light on my PWS and my Ruger. I like that the mount/light combo is simple and relatively cheap. I have the light attached to the left side of the forend so I can just push my left thumb forward to turn the light on. Also with the light in this location it is fairly easy to sort of roll my right forearm up over the top of the rail and push the switch with my right thumb when shooting off the support shoulder.
