    Help me build something better than a KAC SR15 14.5" upper

    Well, the challenge is out there, given that KAC doesn't make the SBR 14.5" dimpled barrel upper anymore I'm looking to build one that's better and I need your help fellow m4carbiners! So lets do this! Money is of no issue but if something better can be built that cost less that would be a plus, otherwise I don't have a budget. Upper will be going on a noveske lower.

    That's going to be tough considering their E3 bolt and new gas block.

    Better? Can't be done. It's like building a hot rod in your garage. You can drop in a bigger than stock engine in an LS460 and be faster in the quarter mile, but without spending the big bucks on R&D and thousands of hours of testing it's not going to be as smooth and dependable as a factory Lexus.
    The beasts of modernism have mutated into the beasts of postmodernism—relativism into nihilism, amorality into immorality, irrationality into insanity, sexual deviancy into polymorphous perversity. And since then, generations of intelligent students under the guidance of their enlightened professors have looked into the abyss, have contemplated those beasts, and have said, “How interesting, how exciting.”

    I'm sure salient or legion will take all of your monies for a super AR.

    Don't know about "better", but I'm planning 3 franken builds soon. I plan to go BCM BFH ELW-F 14.5 mid length barrel when it becomes available, SLR sentry 6 gas block and will have ADCO pin it, along with using their black nitride gas tube... Used in conjunction with LMT enhanced BCG including bolt (will also be using nickel boron can pin), JP enhanced gas rings, VLTOR MUR upper, BCM KMR 13, Raptor charging handle, LWRC skirmish sights and Surefire SOCOM 3 prong flash hider (for SOCOM mini).... Technically part of the lower but I'll be using VLTOR A5 with tubbs CS flat wire spring and either stock A5 buffer or A3. Lower I'll be using the AX556 (better than SR-15 lower IMO). I don't think I'll have to adjust the gas block very much but I want it to be on the razor' edge of cycling Tula brass max .223 and I'll only be running 5.56 after that. I'm imagining it being a very soft shooting, accurate, durable, reliable, lightweight build that requires minimal maintenance but only time will tell if I'm right.

    SR15s are hard to beat. Why not just get Marvin Pitts to dimple the barrel on one?

    Going to be tough to do with out an E3 bolt and barrel extension.

    I have a SR15 upper, literally the only things left I use are bolt, barrel and gas tube. Receiver, carrier, gas block rail, barrel nut, BUIS, and muzzle device have all been swapped out.

    Is it better? IDK, thats subjective, but it is better for me. Its lighter, it has a longer rail, and the Gas block is pinned.

    I'd consider starting with the SR15 upper and replace modify it as you want.
