I am considering buying a Sprinfield Armory Gas Cylinder from Brownells as a spare, but wanted to know what is different when compared to a USGI cylinder, and how close the color of the finish is to the USGI finish. MB |
The bigger issue is the diameter! I had a usgi on mine but I sent the rifle back for a replacement barrel. It came back with a SAInc gas cylinder. I didn't notice for a long time (when I tried to put my GC wrench on it and found out it didn't fit) The SAInc are larger (I beleive because they are cast not forged). Sadlak makes a wrench to fit "commercial" gas cylinders. I was initially disappointed in losing my GI gas cylinder but in the end the one I got works fine and the gun is more accurate that it ever was.

So, from what you are saying they both appear to be the same; the Sprinfield is a little larger in OD. I can live with that, for the cost. With a discount I can get the cylinder for roughly $40 at Brownells. I am not too concerned with it being cast, most modern cast parts seem to hold up very well. MB |
