Anyone with this upper recommend a buis? Troy and gg&g seam to have good reviews. I like the knights but not sure on only having the small aperture. If it helps this will be mainly a range toy and maybe see a few classes.

honestly, i like my KAC flip ups, both the 300 and 600.
My magpul moe buis is good too.
The troy i have is just ok.
Midwest industries has a nice BUIS.
Some folks have also stated that the PSA BUIS is pretty good, and later models have fixed the need to over torque them snug.
I want to get a set of Magpul pro, as those look to be sweet. That may be a good option as well.
On the KAC the 300m you can pop out the small apertuere ring, and have a larger aperture. its not as adjustable as the 600ms though.
I've also read some good reviews of the A1.5's sights.. i cant reember who makes them though.
