I've had a Gen 2 556R for about 3 years now with only about 1,500 rounds down the pipe. I went out with some family over the holiday and the tip of the firing pin broke off. I was running some red army standard when it happened. I called customer support and they are sending me a new firing pin; I also opted to buy a spare parts kit for 27 bucks. Has anyone else had a firing pin break on them? I'm trying to figure out if this is a one off thing or an on going problem with the gun itself. When I asked the service rep if this is normal he said you can expect this shooting steel case after 1,500 to 3,000 rounds. Prior to this I've not had a single problem with the gun, not even a single jam,FTF, FTE! This and my SCAR 17 were my go-to guns, but now I am reconsidering. What's your long term experience with the system?
