[ARCHIVED THREAD] - Flip down Front sight, weaver base

Posted: 9/21/2004 9:03:47 PM EDT

Hi,

I'm wondering who makes flip up/down front sights that would attach to a weaver type gas block. And also what the plusses and minuses of such a system might be? Are they reliable and hold zero and so forth.

-Thanks

I was mainly looking at the RRA gas block for this. As of now I can only find their detachable front sight. Are there any other options?

Also, how hard would it be to switch from that gas block to a PRI flip up front sight block?

You can use the YHM-9584 flip sight for railed gas blocks, it's a very tough setup -

here's a true pic of a forearm mounted YHM flip sight -

As long as you're dealing with a .750" barrel you could also use the PRI or the YHM flip up gas block sight assy. -

Thanks BrightFlashlight,

Are there 2 heights of front sights for the YHM-9584 flip sight or is it just one height for rails/gas blocks? Also, how difficult is it to swap out one gas block for another? Is this a gunsmith only type operation or is it something one can do at home with the right tools?

There's the 9584 which should fit most railed gas blocks and then there's 9627 which will mount on railed forearms that match the flattop receiver heights.

Swapping out the gas blocks is really not that hard, the worst part can be getting the pins out depending upon how tight they are.
