UTG 727 destruction

not a clue, but i seem to remember hearing that when you are building a 727 for a vehicle that does a lot of burnouts (think of warming up the tires for a dragrace) you would want to replace the stock sprag with a bolt in one
They are pressed in on a 727 ... riveted in on a 904 which is why you never see this with a 904.

A bolt in sprag is the only way to go whenever building a 727 for any application. I've seen them go out like this in RVs.
