New sign up from out in Aurora. Currently I own a Bushmaster Carbon-15 and typically shoot at the range in Cherry Creek State Park. Signed up to learn more about the system as a whole and what others have done that either worked well or didn't work. I served 7 years in the Army and took the battalion armorer's course, so I am vary familiar with the basics of AR-15 rifles, but I have limited knowledge of accessories. So far my current rifle just uses the red dot sight that Bushmaster slapped on it, but I am looking to change that and the forward grip soon.
