Since it's been removed from the default Cycler. I'm assuming the SABR gets it, but what about the other burst-fire variants? They should add a way to preview the attachments weapons get before you buy them (outside of the buggy trial weapons).
Cycler S gets it. Cycler S also has the same Fire Rate as the base Cycler as well as a host of other mods (grenade launcher, ammo, etc). Also comes with 3 round burst fire mode and single shot mode in addition to automatic. If you like the Cycler, you'll like the Cycler S. I believe the only down side is it takes slightly longer to reload. Also pretty sure you can still left click on the weapon and see all the unlocks for it even if it's in Red.
You can see which weapon attachments are available, just click the gun name and it will expand to show what is available for it.
Goes for pretty much any weapon, the S variant just offers you more options while not really changing anything.
