They seem to be gaining a reputation for busting bolts...
I would wait and see if they get this fixed
They also need to offer chrome lined barrels and chambers
as they do with their AR15s...4150 steel
imo
On my SR-25 I recently had the chromed extractor break - the edge just chipped away. I suspect the hard-chromed parts can be a little brittle. The problem is, I figure that I shot less than 1000 rounds through it. Knight's quoted me $100 for just the extractor. I got an Armalite extractor for $30 and it works just fine.
