Wanna buy MCG Grip. Am I right this is only grip, without a base?

Looks like there is no gunfighter base, avaliable to buy. If so, is it temporarly?

That grip is RevB and won't fit the current version of Gunfighter, which is RevC.
The EU store is expecting new stock though, should be there in about 2 weeks, so you could get a combo base and grip soon.
