Purchase Advice - Carbine and Bullpup

With the election results from last night, we are likely 2 years and 9 months away from an assault weapon / magazine / NFA item ban. I'm planning on purchasing items that I've been putting off, including a SCAR, an SP5, a lower to SBR, magazines for any handgun that I may want in the future, and .223 and 9mm specific suppressors.

To go along with the suppressor, what's the best carbine AR that comes with an adjustable gas block? Since this is "forever" I want it to be the highest quality.

Also, I've always wanted a bullpup and it's between an AUG and X95. The safety on the AUG is very uncomfortable, but I've seen there are ways to mod it. I know the triggers on bullpups also aren't great, so what's everyone's opinion on the best aftermarket bullpup trigger?
