I am looking for a pistol grip for a bolt action chassis with the closest to vertical design I can find...sure I can mail order but I am anxious to get something andgo play asap. Wanted to see if anyone had run across any of these?

BCM gunfighter grip mod 0
Tango Down flip grip
Magpul K grip
Umbrella Corp grip 23

or others I may not know about?

Thanks!
