Bought lifters from Bullet once...got 12 of one manufacturer and 4 of another. Drastically heavier than the rest. Sending them back would have been a loss... so now they sit as an example of how sometimes people ,no matter who they are...will just say 'fk it'..and give you garbage to make that dollar.
