B5 Systems Collapsible 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. 

• The stock features internal tensioners to help optimize fit on Carbine or AR10 Mil-Spec receiver extensions
• 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
