Pistol Build ideas?

[EastTexasAg]

So folks, total new guy here. I?ve never built an AR more than buying a complete upper and building a lower myself. That being said, I?ve decided I want to build a 10.5-12? Grendel pistol. I?m tired of toting my 24? monster anywhere but the bench. Lol. Anybody have any ideas or advice on the project? All I know is that it?ll end up with a thermal/NV just to knock down swine at a seconds notice day or night at this point.
