Most Helpful Positive Review Most Versatile and Adjustable Precision Stock on the Market
This is by far and away my favorite precision stock. I run this on both my Ruger SFAR and a 16" Geissele DMR setup, both with MPVOs on them. What I have to say to get my performance really quick, is make sure your buffer tube (which this attaches to either a standard carbine buffer tube, or an A5) is secured tightly to your lower, then you should have an extremely consistent and stable platform. If you like to Larp like me, this stock has gross manipulation allowing you to adjust length of pull of the stock rapidly like any other carbine stock, but it also has extremely fine adjustments to r...

Love my new stock

by Stephen McCarthy, Verified Owner from OH, United States Written on January 21, 2026
I installed this on my AR. I had the Magpul PSR light and when installing the new B5, I needed a buffer tube end plate. When ordering check to make sure you have a busser tube and plate on your knee AR so you don’t run into the same problem.

fantastic stock, but....

by bretta snob, Verified Owner from AL, United States Written on December 10, 2025
I wanna start off with saying i love this stock, it's on my m5 308 build, great looking adjustable stock, for the price, It's perfect, but the only con, is the buttpad size, it seems small... i went from a magpul dt-pr and while it gave me the upgrades i want, the sizing doesn't fully add up.

by MiiX, Verified Owner from GA, United States Written on November 27, 2024
This stock provides the proper adjustments involving cheek weld and buttpad with precision dials. I can't see myself wanting any other brands out there as this supplies me with increased comfort while at the range. A must have for AR and M4 owners

Rock steady and easily fitted

by RoeDoe, Verified Owner from VA, United States Written on November 3, 2024
I have several different brands and styles of these type stocks. Wanted a collapsible to experiment. This exceed my expectations. Really solid and seems to hold adjustments but time will tell. I like that. The rest is fine tuned with the stock adjustment.
Pros:
  • solid
  • Most of the LOP adjustment can be done by moving the stock on the receiver extension
  • Easy install, no adapters needed
Cons:
  • none yet
Would recommend: Yes
