- description
Red tracer ammunition needs a different charge wavelength from green, which is why most units quietly only list one. The Bifrost R does both, so a bag of red BBs is no longer a waste of money.
Four modes give you more control than the usual two. Rainbow flame cycles the colours, RGB single-colour holds one, flame only works on standard BBs, and tracer only drops the flash when you want to stay unremarkable.
It is CNC machined aluminium rather than moulded, charges over USB-C from an integrated cell, and ships with a 10mm CW adapter alongside the standard 14mm CCW female thread — which covers a lot of pistols that would otherwise need a separate part.

Good to know before you buy
Standard BBs will not glow in this or any tracer unit — they trigger the flame effect only. The red and green support is about luminous ammunition specifically.
Frequently asked questions
How is this different from the standard Bifrost?
The R adds red tracer BB support and a fourth lighting mode, and includes the 10mm CW adapter. The standard Bifrost is green and flame.
Does the 10mm adapter fit pistols?
It covers the 10mm CW muzzles common on GBB pistols, which saves buying a thread adapter separately.
Can I turn the flame off?
Yes, tracer-only mode does exactly that. Worth knowing if you play night games and would rather not light yourself up.
