Excellent product - Geissele Super Charging Handle

Ergonomical, fit and finish good, smooth engagement, well made, good choice for gloved users and scoped weapons. Would definitely recommend. Geissele prices gets you Geissele quality. I don’t know about the gas redirection claims for those that use a can. I don’t see anything special about this that would redirect blow back however I cannot confirm because I do not use a can.
