>>9469462There are some springers and flywheel blasters that have magwell options for angled talon mags. And there are angled magwell adapters that will work in plenty of blasters with full-length magwells.
The Hummingbird is a flywheeler that's no mag-in-grip.
The Talon Claw U Bullpup has an angled magwell option.
The Freedom Blasters Lamia has one (but reversed).
And a few other platforms have remixed magwells for them.
