    Check out the URX4 install video, too complicated for me. Part of the reason the Mod2 gas tube & gas block were completely changed I think is to make life easier if you ever want/need to remove the URX4 rail... Another thing is KAC is not selling Mod2 uppers, I don't believe anymore mod 1 uppers are being made so you may be need to be very patient in waiting for thr mod2 uppers to leave the factory, I doubt we'll see the uppers anytime this year. As great as KAC stuff is out of the box, IMO it's not really worth that kind of wait.

    They may be mod 1's with the URX4 they are calling "mod 2s", Tom P. from KAC who would be in the know reported on TOS mod 2 uppers would not ship until at least end of year (and KAC is generally a little slower than they predict when releasing new products)... Perhaps they started shipping mod 2 uppers already but I doubt it, so I'll venture to say it's either a mod1 upper with a URX4 or they separated a Mod 2 upper and lower to sell seperate (not a bad idea since many want either or and nobody is really selling KAC lowers or mod 2 uppers at this point). The listing makes no mention of the Mod2 gas system so I'd want hard confirmation from AV if it is indeed a mod2 upper.

    ... And looking at a price of only $1300 makes me believe it is likely a mod1 with URX they are calling a mod2, I believe a true mod2 upper would fetch significantly more ($1,700-1,800) at this point.

    Lastly in this are you aware KAC discontinued the dimpling because of user feed back? Apparently in jungle environments dirt and mud got stuck int he dimples.

    If you're trying to build 'better' consider dimpled might not actually be better. Now if you live in an arid environment it might not be an issue.

    Just food for thought.

    I have read that before on another forum, plus since it is a lightweight barrel already I don't think dimpling it would be necessary unless it's for aesthetic purposes.

    OP if you are interested in a Mod 2 upper, I have some mod 2 rifles in stock but I have a customer who only wants a lower. If I can find a buyer for the upper then i'll part them out. PM me if you are interested.

    If I go with the mod 2 or mod 1 upper what kind of buffer tube kit should I get? I have a VLTOR A5 buffer kit readily available.

    From the pic, that's a genuine mod 2 upper. Must be a take off.

    Lasering on the left side of receiver.
    Gas block relief cut in the URX4.
    The gas block and gas tube retainer nut look correct, but can't say for sure.
    Together, the upper gives a strong impression of being correct.
