I was one of AA extractor and bolt tester back early 2008 and earlier. The bolts after the testing resulted in beefier points in the relief cuts and improvements to the bolt/extractor mfg. process.I will keep it at that. =0)
As I stated earlier. This is the Internet. Do your own research and go from there and use the Internet resources as is - face value. :)
I made my own decision that it's well worth it and left it at that. If I end up not liking it. I will sell it. Simple as that.
I agree with Meat. Have several SWAT and ex-military buddies who have used the SCAR platform in the field and couldnt state more clearly as Meat did. Don't believe everything you read on the internet rather go to the primary sources (if possible) to get your answers.
