I just bought this last week. I purchased a Kriss Vector pistol, and wanted to add the folding arm brace stock. When I got the gun, it already had the adapter on it, so this one, which cost me $80.33 can be yours for $70 cash. That's better than paying return shipping and a restocking fee. My loss can be your gain. Cash only, face to face in northwest Plano. Thank you for looking, check out my other listings.
