BERETTA B-FAST tuning/replacement part for rifle, comb set for retrofitting

B-Fast system for the adjustable buttstock. Via 2 stainless cylinders attached to the stock, the buttstock can be adjusted in almost any desired direction. Using differently thick plastic spacers, the buttstock can not only be adjusted parallel to the stock but also the angle of the buttstock to the stock can be individually adapted. Both cylinders are also adjustable laterally, so that the buttstock can also be extended or retracted. The effort required to install the system is not less than 6 hours and should be carried out by a skilled professional.
