Can I get some tips for my AR build?

I went with this company. Sourced a quad rail elsewhere and I’ve got a stock assembly already. Going 10.5” 5.56. Plan on getting a shorter 300BLK upper later down the line.

I got my 300BLK shortie from Palmetto State Armory. Great prices and even better prices on slightly blemished ones.
But they wont ship to you in MA. so you either have to have it shipped out of state to a friend or shipped to an FFL that is willing to do it. They shouldn't charge you anything for it.

Barrel and trigger are the most important parts IMHO. I use White Oak barrels and love Rock River 2 Stage National Match triggers.
