FWIW - I've had a FO front sight on my Trapper for almost 10 years, w/o any issues. (lowermost rifle)
BTW - I believe the front sight in the Williams Firesight Peep Sight Sets are short, since they're designed for regular carbines with ramp-mounted front sights.
Trappers have front sights mounted direvtly in bbl dovetails, so if you're interested in a Williams set (they're available with either a 5D or FP peep sight), I would suggest telephoning William's Customer Service to order, so they can supply the proper height front FO sight with YOUR set.
