Just wondering if the current Bushmasters are good rifles. I'm looking at one of these on Atlantic Firearms, specifically the XM15 Patrolman model. I'll be purchasing my first M4 Carbine in a few months, but I don't know much about Bushmaster. I noticed that their parent company is Remington....that gives me pause for concern, thanks to Freedom Group's screwups. I'm also looking at Ruger, Windham Weaponry, Colt (if I can find the 6920), and S&W. Thanks!
