It looks like the Typhoon F12 handguards are Keymod and I was not able to find any with an M-lok handguard which means this grip will not work. Please email us at techsales@opticsplanet.com with either an image or link to your model of F12 and we can confirm what options will work.
The Typhoon F12 sport does have m-lok slots on the sides and the bottom of the handguard. The classic model of the F12 is more limiting on customization. So my advice is order the F12 sport model. If you have the sport model this VG will absolutely work. There is NO keymod on this shotgun.
