B5 Systems Precision stock

The new B5 Systems Precision Stock is a fresh look at an adjustable stock for a standard Mil-Spec carbine receiver extension (buffer tube) or an A5 receiver extension. 

The stock utilizes the gross adjustment holes on your Mil-Spec extension and then has tool-less comb height and length of pull adjustments as well to "dial in" the rifle to the shooter.

  • Two (2) Anti-rotation QD swivels, one on either side
  • Two (2) ambidextrous hard points for traditional sling use
  • Tool less comb height and Length of pull adjustments via quick thread adjustment dials
  • Two (2) separate M-LOK sections on the bottom to accept monopod or accessories

While the stocks are fundamentally the same, the 5.56X45 / carbine has a slightly longer cheek piece, the shorter of the two (the 7.62X51) is to allow the operation of the charging handle.
