Oh, thanks for your input buddy. The gun I wanted to sell already sold lmao, so it really doesn't matter at this point. Was asking a serious question but it's clear you can't see past your neckbeard. Get off my post kid.
That's the only thing that worries me about 300. With the sbr I'm building in trying to make it quiet as possible for fun, so I feel like 300 is the only way to go.
A buddy of mine builds AR's himself a lot, every time we take them to the range they perform just as well if not better then stock AR's. Haters will hate.
