Most Helpful Positive Review Magpul ACS-L rifle stock
I have always liked Magpul products. I intended to acquire an ACS stock, however, I ran across the lightweight version (ACS-L), tried it and decided it fits the bill better than the heavier model. Now that I have had it for a while I am very happy with the ACS-L on my AR-15 light build. Saves a few ounces and actually looks better.

Just buy the ACS

by Fang333333, Verified Owner from AZ, United States Written on March 28, 2025
I am so ticked off. I wanted the ACS for many many years but never got to ordering it. I have everything for my AR-15 planned to a T, including storage compartments and what I need them for. I needed storage compartments for the batteries. After waiting a week, and with much anticipation and needing it for a planned weekend it finally arrived. After many years of wanting to upgrade my rifle I finally got the stock I wanted! Only I didn't.
I quickly noticed I do not have the much needed battery tubes, the very reason I chose this stock over every other brand and type. No. I got the "L" version, which stands for LOSER version.
Why... FOR THE LOVE OF GOD...Can they not just name the stock a different name to avoid confusion? Or a better question. WHY HAVE A "L" (LOSER) version AT ALL!? If you don't need the battery compartments DON'T USE THEM! At least they are there.
The weight difference is negligible. Its such a dumb concept. Now I have to wait another 2 weeks, have a ruined weekend, get my money tied up, go through a return process, all becuase we have to have the same color, look, branding AND NAME of a stock, but minus the feature that matters most. All so a small group of people can have the placebo effect of savi...

Pretty good

by Cornelius, Verified Owner from TX, United States Written on March 8, 2025
I love the amount space you have for your cheekrest as well as the extra storage space it comes with. However the QD mount that it comes with is a pain to take on and off. Other than that I love it. I would recomed this for a friend.
Pros:
  • Storage
  • Cheek rest feel
Cons:
  • QD attachment point
Would recommend: Yes

Great slimline stock

by ShreikingRobots, Verified Owner from WY, United States Written on January 31, 2025
If you want a solid stock that is bigger than a CTR stock but not as wide as an ACS or an STR stock, this is the one. It's just as sturdy as any of Magpul's other friction lock stocks, but it allows you to get your face closer to the stock that any with battery storage tubes.
Pros:
  • Storage
  • slim
  • Sturdy
Cons:
  • None
Best Used for:
  • large AR15/AR10 rifles
Would recommend: Yes

Fits Very Well
