Depends what the inside looks like.
They didn't have the steel washer inside, its my understanding.
Otherwise around $200 + or - is what they seem to go for.
solely depends on if the breach has been mushroomed or not.
Off topic, what's the forgrip?
venomous designs foregrip i believe.
looks more like an axe forgrip or whatever the other one of those markers were called
No, that is a Venomous Designs product.
The foregrip was a venomous design custom/prototype foregrip which i believe led to the EP grip.
