[QUOTE="Buck Fever, post: 1918290, member: 113501"] The breakage I have read about was in the several hundred rounds range. In a 5.56x45, the bolt life of a good bolt is in the 4,000 round range on guns that are more likely to be abused. That is significantly worse on the Grendle (still intentionally spelled that way) and much less than I would tolerate on a $60+ wear item. When Grendle was proprietary and Alexander Arms was the only game in town, it was worse, the bolts were more expensive and the failures were pretty common. There was no "Eureka!" moment where they fixed it, cheap box ammo just reduced the pressure is the only reason I can see for the bolt breakage to slow down. What does that mean? First, the Grendle bolt is highly stressed. Second, you never know when you are going to lose a bolt. When exactly do you life out a bolt? [/QUOTE]
