    KAC buis micro or standard rear?

    I'm looking to purchase some KAC back-up sights. I'm having trouble deciding on the rear sight though.

    I'd prefer to have the normal non-micro version for the front sight out of preference.

    Is there any real difference betweeen the micro and standard 200-600m rear sights?

    I've heard the micro is MIM, and the standard is alloy?

    Durability same?

    Thanks

    Micro for sure. Seems like the only real difference in the lower profile windage adjustment (been a while since I've compared side-to-side, sold all my standard for micros). I don't know about you but I don't really dial windage with my rear sight, ever, on an AR.

    Echo front sight. I also like the standard over the micro.

    Durability I can't see being an issue unless you have a habit of torquing your irons sideways while in the up position. I'm not even sure how you'd manage that unless you were trying. I've never had any issues with my KAC's in any situation, from concrete bench to run and gun down in the dirt.
    I'm not cool. I just do this stuff for fun.

    Based on my experience with both, I'd strongly recommend the full size. I had a micro where the windage knob would click when you flipped the sight up and down. It wasn't consistent either. In other words, sometimes it would move two clicks when lowering the sight, but not click back when you raised the sight. See how this can be an issue? I've heard of others having the same issue. I sent the sight back to KAC. Their response was to send me a full-size.

    My 600M Micro's elevation adjustment stalk got loose while shooting and the peep sight portion of the stalk dropped off, never to be found again. I haven't bought a Micro since, but I keep buying the old style 600M BUIS



    KAC sent me a replacement, but shipped via Fedex that required a signature. I couldn't be home to sign for it, and one day left work early to come home to wait for the Fedex guy, only to find he had got here earlier than the last two times. I was furious and called and got a refund

    Micro! Buying these feels like a kick in the nuts but they're definitely worth it.

    Interesting, didn't realize there was that much difference between the two. While using the micros, I never wanted a larger knob...the smaller one worked just fine with my clumsy hands.
