Same here - Techt L7 is a great bolt IMO, only weakpoint being the inner bolt stop o-ring. This is a special size (not std. SP kit) and only needs to wear a little to give leaks, because seals fit on bolt tail isn't very tight when new.techt L7 is deffinatly a good bolt to get,
can be slightly difficult to install if ur not sure how to, but once its in, its a one of the best
also, how did you brake your bolt?
