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.
There is no hardware needed, the grip directly integrates with MLOK slots.
It will depend on which stock model M&P Sport you have as some models do come with an MLOK capable handguard from S&W. This grip can only attach to MLOK.
You would need a 7mm Allen wrench.
The Magpul Industries M-LOK MVG Vertical Grip will only fit your S&W M&P-15 if you have an M-LOK handguard equipped to your rifle. If you are unsure of what style handguard your rifle has, email us at Techsales@opticsplanet.com for assistance.
There is not a cover for the bottom of the Magpul Industries M-LOK MVG Vertical Grip.
The Magpul Industries M-LOK MVG Vertical Grip is compatible with any rifle or pistol that uses an M-LOK rail system. If you unsure of what rail system your rifle has, email us at Techsales@opticsplanet.com, or reach out to PSA directly for assistance.
The Magpul Industries M-LOK MVG Vertical Grip is 3" long.
The Magpul Industries M-LOK MVG Vertical Grip is polymer and not a rubberized grip. However, the Magpul Industries M-LOK MVG Vertical Grip is texturized so it isn't slick.
The Magpul Industries M-LOK MVG Vertical Grip will only attach to MLOK rail. So it will not work with a LVOA rail.
