I am thinking about collecting parts to build a 300 BO in an AR pistol. I am wondering what you all recommend. My thinking behind this build is just because it would be a fun gun and also deer hunt with it on public ground. I have seen 8.5" and 10.5" barrels are common. I don't plan on getting a suppressor. Any suggestions on using a flash can or A2 hider? I know there are several members on here who have built these guns. I am just hoping for advice on your experiences. Thanks.
