The Waldo Dynamics Crimson 70° is a GBB bucking for heavier BBs (around 0.30 to 0.45 g and up) and heavy or steel bolts, where it works better than the Crimson 65°. It is designed to prevent over-insertion in the chamber.
Fits: Most GBB hop-up chambers that take a standard GBB bucking (VFC, TM-style, and many clones). Not for AEG hop units.
In the box: 1× Waldo Dynamics Crimson 70° GBB bucking
Tip: Seat it fully without forcing it past the stop, and clean the chamber first for consistent hop. For mid-weight, all-round use, the Crimson 65° is the better fit.
