Welcome to the forum. Never had an AR before?? It's ok. Just let someone here hold onto your wallet for you...it's gonna get a little workout in the near future. Don't worry...these guys will all be there to support you as you spend away on new toys. One just won't be enough, and after you buy a few parts to replace you'll find the parts you took off sorta start to morph into other rifles. Don't feed it after midnight and never let it get wet.
