Vertical foregrips?

[Gunhead]

I recently got this swiss baby and I want to pimp it out with some accessories. The carbine will be used on indoor IPSC/3-gun matches. I need your opinion on vertical foregrips (like the K-grip+adapter, or the KAC RAS/MWS) because I think a grip arrangement like this feel more natural to me. Not sure about advantages if there is any...

I know that a vertical foregrip is now on my list for making my shorty AR. Shot 3-gun today, I think the vertical fore would help you get back on quicker for follow-up shots.

I generally dislike vertical foregrips but that's me. It's a matter of personal preference. I like forward slanting grips as these make shooting from the shoulder a bit more comfortable. I am, however, used to shooting without it and since ALL my weapons don't have the grip, it makes it a bit awkward switching between them.

Thanks guys!
