How do you know you got an A1 bolt? Can you tell the difference?
I’m waiting for someone with both bolts to take them apart and show them side by side, and take some measurements. I read somewhere they made some slight changes to the internal components to make them slide a little easier, which helped the external surface of the bolt slide in the chassis. But the bolts would still be the same dimensions and have the same bolt head connections, therefore being backwards compatible with the A1, Gen2, and Gen 1 chassis.
