I posted on another forum and someone suggested that I ask over here so here goes.  I have been looking for a carbine barrel and determined them very hard to find.  As an alternative, I am considering using a Criterion barrel.  Does anyone have experience with these barrels and, if so, how would you recommend installing the front sight?  Many thanks and I appreciate any help I can get.

PS - I guess an alternative question is should I hold out and keep looking for a carbine barrel?  I have a 1896 carbine that has most everything but the barrel and a few other bits.  Many thanks again.
