Most Helpful Positive Review Great Product and Customer Service
The first magazine I received didn't fit correctly and would cause a jam. I sent Compmag an email explaining the issues and within a few days (I think they were at ShotShow2020 or would have responded sooner) the president of the company responded to me, offered to send a new magazine. The new Maga...

Most Helpful Negative Review It comes out
Hi, as most of you know here in California we need to ether have a featureless ar-15 or a locked mag Ar-15. I bought the compMag because I wanted to keep all of my legal features on my AR-15. I followed the instructions, they ask that we do not do more than a certain amount of turns on the screw. I ...

Too much hassle, too expensive

by Preston Marrott, Verified Owner from CA, United States Written on March 7, 2023
The concept is cool. A magazine that doesnt need to be removed. It fed fine for me and I never had any issues with it working.

With that said, it was very annoying to use. Trying to load it from the side window was such a hassle. The bullets would spin around and then get stuck inside and wierd angles. I would rather just use a takedown pin solution. Way easier.
Pros:
  • compliant
Cons:
  • None
Would recommend: No

false advertising

by Ethan Koch, Verified Owner from NY, United States Written on November 20, 2022
So a little over a week ago i decided to order this item and just the other day I went to use it and my bullets were get jammed and it was not feeding anything so I decided to take a look and the whole top half of the magazine was cracked and scratched so for $70 this mag is so not worth messing up a gun. It has to be the worst mag I’ve ordered. And for the screwing to expand the mag that in fact does not work. Id keep my money and walk away before I buy another one!!

Great Product

by CJ, from PA, United States Written on February 3, 2022
Solid product for what it's worth, I use this on rifles that I want to keep compliant for neighboring states when I go shooting with my buddies. Plus Optics Planet gives the best price I could find!!!

Not sure on it

by JR3HP, Verified Owner from NY, United States Written on May 13, 2021
I would add a separate mag lock for this thing as it pulls right off with some force. You think a LEO that wants to ruin your day out isn't gonna pull hard to remove one of these mags... hence eliminating the compliance with the NY SAFE act. I would buy this only for the neat loading design that could feasibly help clearing a jam....then again I got a weird bolt jam using some steel case and I don't know that the mag didn't contribute to that. Could have been a fluke. If it doesn't jam again I may come back and upgrade my rating. In terms of loading speed you're better off with an ejection port speed loader.
Pros:
  • novel
Cons:
  • False advertising
Best Used for:
  • range toys

Good product but it has room to improve

by Jay, from CA, United States Written on March 6, 2021
I bought one from opticsplanet, fast shipping, reliable stock and there is no fake product from here. As for the mag, I have their Gen 1 and this is the Gen 2, I like the Gen 1 better, Gen 2 is easier to set up you just need to insert the mag and tighten up the tension screw then you are good to go, but the safety pin always drops out when you open up the action, that is why they gave you two(it still works without the pin), I hope they still make the Gen 1 in the future or keep improving the product.
Pros:
  • Make you AR legal in Cali
Cons:
  • Make your AR legal in Cali
Best Used for:
  • Behind enemy line
Would recommend: Yes

one of the best option for restricted states

by OCT, Verified Owner from NY, United States Written on August 5, 2020
Easy installation, easy loading, good looking (better than 10 rounds mag IMO), easy to clear double feed.
Especially if your state only allow you to have a fixed mag or featureless ar15
Compmag also works with my cross armory mag lock system which is even better.
Pros:
  • None
Cons:
  • pricy
Best Used for:
  • AR - 15
Would recommend: Yes
