I'm just getting into my first sbr and wanted to ask for some advice regarding anything you guys think I need to know. It will be an ar chambered in 5.56. I'll be getting an 11.5 lightweight bcm upper once i sell my 14.5 ballistic advantage upper. The lower I registered has an A1 stock with a LAW folder, geissele H1 buffer with the braided spring. I'll be adding a surfire warcomp as I think they do a good job with flash suppression and I have good experience with them.
Should I go for a heavier buffer?
Any good ammunition offerings in 5.56 for an sbr? Lighter bullets? Heavier bullets?
Let me bask in your infinite knowledge.
