    is there any real difference? i know the height difference, placement, visual, etc but is there any real advantage to having one over the other?

    basically im trying to decide between a low profile gas block and forend mounted sight vs railed gas block and gas block mounted sight

    It's "possible" that if you have a front sight mounted on a free-floated rail, you could lose zero as the barrel gets hot. I've never seen this with my own eyes though. I don't really see a point in flip up front sights :dunno:

    I'd like the ability to swap between an electronic optic and a scope and i don't want the front sight getting in the way of the scope :dunno:

    if you are building your own, and thus have to install a gas block, anyway, I'd go that route -- so long as your intended rail system wouldn't cover the gas block.


    I definitely think that "flip up" is the way to go... I have an eotech, and I promptly wanted to cut off my fsb. Much better without it.

    It's already built. I'm upgrading.

    I have a midlength upper if that matters. :o

    So if you have an Eotech then you obviously store it switched off, so when you're not at the range, do you leave your folding sights up? Otherwise in an emergency you'll have to "fix" your rifle by either turning on the optic or unfolding the sights. It's splitting hairs but I prefer simplicity.

    That's why I have fixed sights with a lower 1/3 co-witness. With spank's setup I'd do a fixed front and troy folder :cool:

    They are, the 516. It will run on 123's and have side buttons and no dumb arms levers. Soybomb can't wait.

    Even though I love the idea of CR123s, I'm doubting it now, and would rather have it in AA. :o

    I do have several boxes of CR123s handy. :hs: But they are for flashlights and stuff. But meh, maybe i'll change my mind by the time they come out. :o

    When is the release? dont see shit at EOTech's site.

    No ETA yet to my knowledge. Dealers were backordering them at shot though. I lurve 123's. Long shelf life, they don't go to crap in the cold, they're shorter so the battery compartment can be smaller, I can carry 2 on the gun and they can be put in the light on my gun or the sight. The AA....I can't fathom a reason to have it :big grin:

    Cost and availability>CR123s

    But, if you factory in the cost of lithium AA, then well, moot point. :o

    Exactly, you've probably already got a couple 123's on hand for flashlights anyway, the battery life of the eotech on 123's is supposed to be over 1000 hours (that'd be 125 days of 8 hour shifts!) and if you're really in a pinch you can pay a few bucks more and buy them at walmart or radio shack. I know some guys want AA because they're planning for the world to end and to need to use rechargable AA's when its just them and will smith fending off the night zombie, but I think for most of us the 123 is it

    But I get first dibs so buy aa now. :big grin:

    You know, the past couple of days, I've struggling with myself on what I buy for my new upper.

    I couldnt fuckin decide. I had a plan. Make it tacticool, but practical. :o

    I wanted to plan ahead for what optics I was going to use. I use to own an EOTech 552, but sold it after a while.

    I'm leaning towards picking up another EOTech again. I didnt plan on buying one, until a new revision is out, which would hopefully have a higher mount. And since the 516 is coming out soon, that seems to work.

    But anyways, I originally wanted a flip front and rear BUIS. But I couldnt decide on the front. My choices were barrel mount, or rail.

    Which then creates another issue for me. Now depending on what setup I go, I had to get a different length rail. Well, not really... but it wont be as tacticool. :coolugh:

    I looked at all the major players for the front sights, both barrel and rail mounts. Ultimately, I decided to just keep the standard front site, since I plan on using the new raised EOTech. This way, it's just simplier. Simplicity ftw!

    I currently have a spare LaRue BUIS. I'm thinking I'm going to sell that and put a Troy rear BUIS.

    Oh, one of things I struggled with a barrel mount sight is, I actually like the the pins holding the FSB. Very secure.

    I dont trust clamps. And I didnt want extra work of having my barrel dimpled for set screws.

    :rofl: My vote goes for a gas block under the rails and then you can put a fixed or folding front sight on the rails depending on what you like. If you're doing it yourself I'd just get a regular FSB and dremel the sight off if the rails will be covering it. It'll be low profile and more secure from the taper pins. Most places will pin a low profile block for an additional charge if you're having one built. If you're going to use a scope though I'd consider just a vanilla FSB.

    i'm going to be going between a scope and (for now) a fakepoint and eventually an eotech...
