ACF-L is an AR15/M16 ambidextrous charging handle based on our ACF. Whereas with the ACF, we kept the T handle nearly the same length as that of the TDP spec charging handle, ACF-L (LPVO) has the T handle lengthened to better work with LPVOs and magnified optics.ACF by design has a short T handle. A short T handle combined with a mildly swept back shape is far less snag prone than a long handle with a forward canting angle, it also doesn't stap the user in the chest or back when the rifle is slung. The short handle does have one compromise: LPVO and magnified optics users need a longer handle to clear the occular lens of their optics.ACF-L's T handle is moderately lengthed from the original ACF's 2.2" to 2.6" (TDP's T handle length is 2.0", ACF's handle is 0.2" longer to protect the latches). The slight increase is just enough to make ACF-L easier to manipulate with LPVOs and magnified optics, but no longer than necessary.Proudly designed and made in USA.
