KAPP Low-Rise Feed Adapter
KAPP Micro Drop-Forward
I had a few problems with the board and battery when I first purchased the Angel.
Both were corrected by Warped Sportz under warranty.
I sold the marker because it never got used.
After having problems during tournies, I never fully trusted it again.
Not to mention that the Ultimate Revenge 2.0 I bought completely eclipsed it in every manner except ROF (which doesn't matter to me).
