I noticed that the new and improved Sig556 Patrol Rifle has a shortened gas system on it. Is there any way to get the shorter gas system installed on an older version of the Sig556. (i.e. get the parts and switch it out, get sig to install it, etc.)
FYI I own a Sig556 ER or 007 model. Not sure about the model or numbering cause I don't have my case or the gun with me at the moment so I'll describe it just so you know what I'm talking about - it's the model that came with the collapsible non-folding stock, toothpick BUIS and fixed front sight; no optics; fish-gill forearm.
Looking forward to hearing all your thoughts.
