I have moved a Bushmaster shaved FSB/Gas Block from one Bushy barrel to another with no ill effects.
I realize that it doesn't work with a sight as it will be off, but for a gas block, it worked for me that time.

It's all about getting the tightest fit between the FSB and the barrel, to prevent gas leaks and misalignment. THAT is why each one is done individually.Originally Posted by OldState
I can't believe they have not standardized this in a platform that's know for its interchangeability.
From what I've read there are some concerns about clamping the block but I have not found any posts claiming actual failures.
The FSB has tolerances, the barrel has tolerances, but by being drilled/reamed together, those tolerances don't matter (as much) and the FSB is held PRECISELY over the gas hole.

I would like to know about failures as well.

I did find this is an old post here:

Being that I intend this to go UNDER a free float hand guard I'm thinking a clamp on will do the trick. Also, I would prefer to not cut/drill the barrel of my new Colt.

If you intend to have the GB under a handguard I would not hesitate to use a set screw type GB.

Unless I dimple the barrel I would think the clamp would be more secure (see link above).
Also if I want to put the rifle back together stock, I can with no barrel modification.

Link not working for me.
By dimpling do you mean dimple for the set screw or dimpling the barrel to cut weight?
Member
Dimple for the set screws.

Gotcha, just checking. Sort of sounded like he was thinking of dimpling the barrel to include the gas block area.
