I know it wasn't one of the choices listed, but I am a big fan of the Daniel Defense fixed sights. They are always ready if you have the proper co-witness so you get used to using them even with your optic on.
Picked up a used pelican case on wheels for a decent price and a necklace for the wife (not my first rodeo), was very surprised at how small the crowd was.
I went about 2 or 3 years ago and it was decent then of course that was before all of the madness. It was smaller than the Fredericksburg show is but that was the first show at that location so it may have grown since. I found some pretty good deals anyway.
Here's my question. If you submit a form 1 to SBR a lower prior to Oct 1 you can't legally assemble it to it's final state before you get your stamp back by NFA regulations, but on the other end it needs to be in it's final state before Oct 1 by MSP regulations. I know there is no 77r in this...
I did paperwork on 1-12 and still no word. On a brighter note the holster i ordered after the gun purchase has been here for two weeks and it came from Israel.
