Magpul ACS-L Stock Milspec (FDE)
by christopher seaver
Always a customer great service and speedy delivery!
Magpul ACS-L Stock Milspec (FDE)
First Magpul product and like it a lot. Much, much better than the standard stock that came on my M&P 15. At first a little loose on a BCM mil spec extension tube but tightened up with the friction lock engaged.

Quality Product and Service
by William EDWARDS
I am a regular customer and have never been disappointed with the merchandise nor the service. I am building my AR-!5 and have ordered everything from Primary Arms.
I love the ACS but never really used the battery tubes. The ACS-L makes it perfect. Fit is tight even without use of the secondary lock. Very tight and nice fit. Love it!

Magpul ACS-L Stock
The ACS-L Stock in lightweight and functioned well on my FDE build. Looks great too!
Great Stock, but...
by Brett B.
The QD cup that it comes with was meant for the full size ACS with the side battery tubes. If you don't want your face cut up by the QD cup or your sling when shooting, then you will have to order the smaller QD cup, the Type 2 sling mount kit.
This magpul stock is awesome, they reduced some of the bulk and weight by ditching the storage cylinders. Fit is nice and tight with the friction lock, very solid, no wiggle. And Primary Arms shipped very fast, ordered Friday eve and recieved Monday afternoon!!!
Good quality. Easy to install and feels much better than the Blackhawk I was using. Friction lock works well.
Excellent upgrade, nice cheek weld, added Length of pull
by Oregon Shooter -
This is my favorite stock for AR builds. It's got the nice cheek weld like the ACS but the "L" version is lighter and less expensive, and I don't put batteries in tubes in my stock anyway. Has the locking lever which eliminates the rattle, also increases length of pull, and my Mil-Spec stock was too short! Small compartment where you can add battery for lighted reticles, small lens cloth, etc
