I am pretty new to the AR Rifle thing, but have the opportunity to get a Double Star M4 flat top, unfired for a reasonable trade offer. I noticed that this brand is not even listed on "THE CHART". Looking into this alittle myself shows that these rifles are Mil Spec manufactured. Am I ok in assuming the Double Star rifles are descent quality, or should I leave it alone? By the way, I am new here and hope to be involved more as I get into the AR Rifle ownership.
