Most Helpful Positive Review Great Solution to California's Liberal Left Demands
As most of you are aware, California has implemented the most onerous rules and regulations in an attempt to corral the already compliant and law abiding citizens of this great State. CompMag has created an ingenious solution to those who possess and wish to participate in the AR industry. This mag will simply clip and lock into place with one swift slap of the palm on the bottom plate. And of course, once in place it is with concerted effort and use of the proprietary pin tool to remove or replace the inserted mag. Definitely a MUST for those wish to remain law-abiding and compliant in Cali...

CompMag for fixed setup

by Mr. Vega, Verified Owner from CA, United States Written on May 28, 2026
For us in restricted zones this is the best choice. It takes a bit to get used to but if you go to a range you don’t have to carry magazines. If you’re looking for the cheapest route this might not be for you since you can just go to Home Depot and DIY a fin grip and pin your stock.
Best Used for:
  • California

It works well and is compliant

by Len082, Verified Owner from NY, United States Written on March 4, 2026
If you unfortunately live in a state that requires fixed 10
Rd mags this is a good option. It has worked at the range with little to no problems.
I think any think that requires breaking the upper from the lower consistently is a good idea. It was never intended for that. So I pick this evil until something else better comes along.
Pros:
  • Allows reloading without separating the upper and lower
Cons:
  • Can jam
Best Used for:
  • range & target shooting
Would recommend: Yes

Easy CA compliance

by Iodoc, Verified Owner from CA, United States Written on August 31, 2025
If you live in The People's Republic of California, you know all about the absurd laws put into place by half brained politicians that know nothing about firearms. This is the easiest solution to appease your communist overlords while maintaining a semblance of your God given rights. It's easy to remove if you ever move to a free state.
Pros:
  • easy to use
Cons:
  • A little bit expensive for a neutered magazine.
Best Used for:
  • Staying out of prison
Would recommend: Yes

Comp mag order

by Phillip Ott, Verified Owner from CA, United States Written on August 27, 2025
I recently ordered this mag and took me a week or so until I was able to open the package (traveling and moving). When I finally opened the package there was the Comp Mag Gen 3 box. I opened the box and saw a black mag. I’ve never seen or handled a comp mag before but as I inspected it something looked off. I then compared it to the photo on the box and aside from being dark black they didn’t look similar. After further inspection the mag that was sent, IN A COMP MAG BOX, was actually a Strike Industries magazine. I had to request a return and shipping it back today. Kind of ridiculous honestly.

Exactly what it is supposed to be

by Tim B, Verified Owner from CA, United States Written on August 4, 2025
Locked right into the receiver and wouldn't pop back out no matter how much I tried. It's going to be secure and unless you use the tool it isn't coming back out so you'll be nice and "legal" when you need it to be.
