I have alot of experience with firearms mainly hunting firearms nothing complicated mainly bolt action guns I grew up shooting remington 788 there was nothing complicated about it. I have recently ventured into the world of tactical rifles the first hour of reading about ehm my brain felt like it was going to explode. So much stuff to take in at once. So many lmt snobs so many colt snobs they just thought everything that wasn't there brand shouldn't be a AR. So truth be told I don't couldn't get any information so i have around 900 dollars tops to spend I looked into rra,stag,dpms and oly some one please help me out I am trying to learn. Thanks Aaron.
