The design of these were close to being just right. The problem is the super high gas system. This is why the "shooters kit" was made. When the gas system is brought way down, these function amazingly. Why didn't Germany reduce the gas way back when? They needed super high gas to work in the Eastern Front. The rifle was rushed into service without the bugs being worked out. All bolt rifles are going to be more brawny and stout than a semi auto plain and simple! a K98 is almost indestructible so the G/K takes a reputation hit because of more broken parts. If it had an adjustable gas system originally, you would have seen FAR less broken parts on these. If you are into building these like I am, you find the best parts and you put them together. If there is a stout reproduction part, you may find it to be more reliable than an original because you really don't know how much abuse the original has had in its life time. These are very fun at the range and I keep telling myself that I am not going to build anymore because of the cost of these things, but I just completed two and am waiting on stocks and I have enough parts to build another. I also don't believe that a complete 100% matching gun should be shot. There are plenty of mismatch shooters out there for that. One this is for certain, no matter which way you chose to go with a G/K43, it is going to cost you!!!
