The buffer works nicely and helps to reduce the metal to metal slap when the bolt recoils back. I also like that you get three of these for when they wear out. Hopefully not soon.
Pros: Great for protecting metal to metal contact on recoil.
Cons: Took a little bit to align the product into second hole and push it through.
