Hello All. New to the Forum, I've been doin some research and alot of browsing for different items. I have a DPMS AR-15 and I'm wanting to get into defensive shooting and maybe competitive shooting with it. I have a "cheaper" scope, a REX, but it has been doin the job up to 450 yards and has held true. I'm needing some advice on what Light to get. Wanting one with a pressure switch. I've read some reveiws on Brownells on cheaper lights and read reviews on high dollar, name brand lights. I'm torn on which one to go ahead and get. Some are saying the cheaper ones are just as good...? I don't know which way to go. Also wanting to put a Red Dot on the side of my quad rail for close range targets. Don't have a clue on which one of these to get. And lastly I'm going to put a Vertical Grip on the front, I've gathered this is more on personal preference and how much you want to spend, because they all look the same to me. Except for the ones that have a storage compartment, Light holders, etc. Any advice that any of you experts have in ay of the stated topics would be greatly appreciated.
