If you study the bolt handle, the design is plenty robust, just looks hinky at first.
Just pray you never have to put any decent pressure on that attachment point, or you may find out otherwise. I pulled on the bolt handle with moderate force to try and remove a stuck case, and ended up with some play in the joint and some wiggle between the bolt body and handle. I sent the bolt in to Barrett to be repaired, and several months later I’m still waiting. A skilled dude with a micro TIG would be my preferred solution if it ever happens again.
