I have been told by a top of the line gunsmith, that he will never use single piece bases. He Found that they are often not machined to tight enough tolerances and the height difference between the fron and the back causes too much stress on the receiver. One of his rifles had a catastrophic failure, which after extensive research, was found that the scope mount caused so much stress on the receiver that things went all out of alignment and crapped out. That being said, I have never heard about that anywhere else so it is obviously a very rare occasion that this could even have the possibillity of happening!APK-223 said:Question- besides saving barely any weight, what advantages do 2-pieces offer? I just don't see why you wouldn't get a solid base.
