Balance Grips by FFFTech/FFFTechnology A basic set of slim grips for the AR-15. (And other compatible firearms) The design was created to have a grip angle of 20°; between A2's 25° and Magpul K2's 17° grip angles. In theory, this should allow for most people to have a comfortable grip, whether prone or offhand shooting. Two designs are available, a standard smooth grip, and a ridge textured grip.
