B5 Systems Enhanced Sopmod Buttstock

B5 Systems has taken the venerable design of the Crane NSWC designed SOPMOD buttstock and incorporated the features sought by military professionals and firearm enthusiasts.

The Enhanced SOPMOD features color matched steel hardware, one piece anti-rotation quick disconnect sling mounts, non-slip cushioned buttpad, sure grip stock latch, and dual water resistant storage compartments.


  • Ergonomic cheek weld
  • Color-matched steel hardware
  • Overmolded steel anti-rotational QD sling mounts
  • Fixed sling mounts
  • No slip cushioned butt pad
  • Suregrip stock latch
  • Dual storage compartments
  • Made of Milspec materials and finishes
  • Fits all Milspec AR15 receiver extensions

Pull the adjustment lever down and away from the stock body. While holding the adjustment lever away from the stock body, slide the stock onto the receiver extension. Once the stock is on the receiver extension, then release the adjustment lever to allow the stock to fully engage with the receiver extension.

Battery Tubes:
1) Remove the stock from the receiver extension tube.
2) Twist the battery tube cap towards the slot opening (center of the stock).
3) Pull the battery tube from the buttstock. Note: the flat side of the battery tube must be positioned towards the center of the buttstock.

1) Pull cap from battery tube.

    Love it. So much more comfortable to shoot my AR rifle with the better cheek weld.

    Another Great Product for Your Buck!

    The stock is somewhat smaller than expected; which turned out to be even better for my application use. The Goods: Constructed HEAVILY Tight FIT Very ERGONOMIC Built-in QD The Bad: I need 3 more for my other rifles!

    Purchased this stock because I was looking for a better cheek weld and more stability than the Magpul MOE stock I previously used. Stick fits super firmly on mil spec buffer tube, positive locking, and the cheek weld you could almost take a nap on. Very satisfied with the fast shipping and excellent quality of this stock. R/

    Lowest price anywhere and super fast delivery. Very pleased with whole process and glad that I didn't get HAMMERED with a ton of emails... Like a lot of other online stores! I will definitely be using SKD for future products purchases and even got a cool SKD sticker in the deal. Keep up the good work and low prices... You guys are awesome!
