They hold the flight firmly "They hold the flight firmly on the shaft—sometimes it’s even difficult to get the flight into place. You can't use an O-ring with these, because the shaft sits at an angle when you look closely." — Tomi-Juhani P. (4/5)
Excellent dart shafts. Flights do "Excellent dart shafts. Flights do not fly off when throwing tight groupings. Darts Corner always has what I need." — Luis V. (5/5)
very strong, only used one "very strong, only used one set so far, threw maybe 200 times, still like new, gripping the flight tight, and dead straight. Very recommended" — Rich (5/5)
