Newbie Question - BUIS for SIG 556

Sorry if this is double-posted - I first asked this on a thread that’s been quiet for a while.

I will receive my 556 SWAT in dark earth this week. I’m new to building up my own rifles, and am still not close to being up-to-speed on the various options available out there.

I would appreciate any guidance regarding appropriate BUIS for the 556 that y’all can provide. I prefer HK style sights, or the type that are used on the Stg. 90/SIG 550 (?).

Is Aurora a good choice here?

Thanks,

Joe

Many Sig owners use the Samson Front ( http://www.samson-mfg.com/ar-15_html/product/QF-FFS-SIG.html ) because it allows the use of any of the AR15 rear sights (Factory Sig front sight is too short).

I prefer a Troy for the Rear Sight


Thanks for that.
