Which front sight to get?

[Poppy83]

I have a Sig 522 and an MBUS. I want to order a front sight for it, but I want to make sure I get the right one. Most of the sights I see are specifying they are picatinny rails. Anyone have any recommendations fro a front sight that will work with what I have?

*Sorry. I've mainly been shooting an AR with a scope and have not touched my Sig in a long time.

You need a dove tail front sight that works with Sig 556/522.

To be able to use your MBUS, you need a front sight that compatible with AR-15 sight height. Like this one from Midwest Ind.:
MI SIG 556 Folding Front Sight

or this one from Samson Mfg:
Quick Flip FFS SIG - Folding Front Sight for the Sig 556 Sight


If you are not limited to AR-15 sight height, Sig has a solid set of sights:

It's quoted for $70 shipped directly from Sig.
