Continuously bringing new innovative products to the stagnant AR-15 market, CMMG has created the RipStock adjustable kit. This AR-15 Micro/CQB style stock is designed to be extremely fast to deploy, low-profile, and durable. This stock kit comes with everything you need to attach it to your lower receiver including the recoil spring and buffer weight. The 6061-T6 aluminum buffer tube features 5 positions that lets you set a predetermined length of pull with the P3 indexing screw. This allows you to pull straight back on the stock and extend it to your preferred length every time with no locking tabs to potentially bind. If you are building a compact PDW style AR, this stock kit is a step in the right direction.

  • Micro/CQB design
  • Hardcoat anodized 6061-T6 aluminum buffer tube
  • Quick deploy system
  • P3 indexing screw allows you set your own preset length
  • Collapsed length: 5.75โ€
  • Extended Length: 9โ€
  • Weight: 15.2 oz.

  • CMMG Micro/CQB RipStock
  • RipStock enhanced 5-position tube
  • P3 indexing screw
  • Spring and buffer
  • Ambidextrous sling plate
  • Castle nut

When fully collapsed, the CMMG RipStock only adds 5.75โ€ to the end of your AR-15 and can be fully extended to 9โ€, allowing you to fit your gun in a backpack and then be able to quickly deploy the stock and be on target in a matter of seconds. This stock kit also includes an ambidextrous sling plate and a castle nut for installation.
