B5 Systems Collapsible Precision Stock Medium OD Green Milspec
The B5 Systems Collapsible Precision Stock (CPS) in Medium OD Green brings competition-grade ergonomics to your Milspec carbine receiver extension, combining a fully adjustable cheekpiece and buttpad with the rugged, battle-tested DNA of B5's legendary SOPMOD and Bravo stocks.
- Adjustable cheekweld and buttpad tuned via precision dials for repeatable fit
- Fits standard Milspec carbine receiver extensions — no special buffer tube required
- 12 internal tensioners eliminate stock wobble for a solid, rattle-free feel
- Ambidextrous fixed sling mounts plus steel anti-rotational QD sling cups
- Underside M-LOK accessory mount for lights, monopods, or support gear
- Proudly made in the USA with color-matched machined hardware throughout
Who This Is For
The B5 Systems CPS Medium in OD Green is ideal for precision AR-15 shooters, competitive marksmen, and tactical operators who demand a consistent cheek weld and length-of-pull shot after shot. It's equally at home on a dedicated precision build or a duty carbine where ergonomic repeatability matters — all without requiring an aftermarket buffer tube.

Frequently Asked Questions
Will the B5 Systems CPS Medium fit my existing Milspec buffer tube?
Yes. The B5 Systems Collapsible Precision Stock Medium is designed specifically for standard Milspec carbine receiver extensions — the same buffer tubes found on the vast majority of AR-15 and M4-pattern rifles. No proprietary or commercial-spec buffer tube is required, making it a straightforward drop-in upgrade for most builds.
What is the difference between the CPS Medium and other CPS size options?
B5 Systems offers the Collapsible Precision Stock in multiple sizes (Short, Medium, and Tall) to accommodate different shooter body types and cheek geometry. The Medium is the most versatile fit for average-statured shooters and works well with standard AR-15 upper receivers. If you run a high-mount optic or have a longer neck, the Tall variant may provide a better natural cheek weld without maxing out the adjustment range.
How do I adjust the cheekpiece and buttpad on the CPS?
Both the cheekpiece height and buttpad position are adjusted using integrated precision dials, allowing for tool-free, repeatable changes in the field. Once dialed in, the adjustments hold securely under recoil. The gross length-of-pull is set by pulling down on the release lever and sliding the stock to your preferred position along the buffer tube, with a lockout to prevent accidental movement during use.
