Rifles with full rail systems, stainless barrels, aftermarket stocks as standard, re-designed bolts and barrel extensions, proprietary parts, etc. are not covered herein. Which doesn't mean that I might not use the Chart as a guideline to begin to evaluate these other offerings, but only as a basis for the article or conversation.
