What to Compare Before Buying
- Thread fit: Check that your setup uses a 14mm counter-clockwise (CCW) thread, or that the included 11mm adapter is the right option for your fitting.
- BB type: This unit supports standard BBs, green tracer BBs and gel BBs, so compare that with the ammunition you use.
- Lighting mode: The Bifrost MKII includes RGB and multi-colour flare effects, so compare the lighting style with the look you want.
- Operating behaviour: It powers on through vibration detection and enters sleep mode after 5 minutes of inactivity, which affects how it behaves between uses.
What Else You May Need
Check that your compatible toy shooting device accepts the stated thread size, and make sure the ammunition you plan to use matches the unit’s BB compatibility.
Before You Decide
Confirm the 14mm CCW thread, the included 11mm adapter and the BB type you plan to use before choosing an offer. If the thread size or ammunition type does not match your setup, a different tracer unit will be needed.
