Most Helpful Positive Review Magpul never disappoints
Bought this stock and loved it from the get go. Installed it and had a perfect fit with my mil spec buffer tube. Literally, no play at all. Compartments to store condoms and viagra is a plus. Cant compare this stock to others because I only have magpul. But I'm super picky and there was nothing to n...

Most Helpful Negative Review Great, except for a couple unacceptable flaws
First the good. Very comfortable cheek rest, easy on/easy off, multiple battery compartments, price is lower than closest competitor (VLTOR) The biggest flaw for me is idiotic design of the release mechanism for sliding and removing the stock. I need to be able to remove and install the stock easil...

classic quality

by B1NICE, Verified Owner from GA, United States Written on June 27, 2026
I see why this one got great reviews! Perfect for my Geissele build. Love the storage options with batteries on each side plus the corner spot. In addition you get a locking position squeeze and set. A little on the heavy side so it you want light weight this is not it.
Pros:
  • None
Cons:
  • Heavier and bigger than most AR uppers (even most pistons)
Would recommend: Yes

Stock locks up awesome with adequate storage. Perfect cheek weld without risers that would obscure the operation of the charging handle.

Great Stock for Storage and Adjustability

by Ben Young, Verified Owner from MS, United States Written on March 3, 2026
The stock is well built and much more rigid than the factory unit. Instalation was easy, and instructions can be found on youtube and Magpul's website. Be advised that the storage compartments are water resistant, not waterproof. The is typical Magul quality which is excellent.

Magpul never disappoints

by Ant, Verified Owner from CA, United States Written on July 1, 2025
I love how the cheek rest feels. Storage is easily accessible. I have two 2032 a couple Allen’s and a mini screw driver in it and it works great. Going to find a cloth so it doesn’t rattle so much. It was a bit difficult getting it on the buffer tube since the tube storage cover the spring that you normally pull down to install and uninstall but used a flat head and it wasn’t so bad.

Good solid stock with the lockdown.

by gunguy531, Verified Owner from NC, United States Written on April 2, 2025
I've used Magpul stocks for about 10 years,I have several models both top of the spectrum to the lowly MOE BUT This is my favorite. Good constant cheek weld.some guys don't like the locking mechanism but it works for me. The only thing I don't like is the way Magpul did the rear swivel mount. I hope in the future the figure out a way to just integrate it into the stock so you can mount it from the right or left without moving that barrel. Other than that is great especially if your using LVPO optics.
