Most Helpful Positive Review California nonsense compliant
Great product, looks good, doesn’t jam, great option for our CA 10 rounds magazine compliance. Even though it’s got to be ejected I didn’t have to reach my belt... just flip the mag! The joint in the middle even works as a guide when securing the mag in your hand and into the well. I bought two at ...

Most Helpful Negative Review Not a good product
I bought this because i thought it was clever and wanted to support a company that hasnt completely abandoned new yorkers with our ridiculous laws. Sadly, I CANNOT recommend this to anyone.

Pretty amazing for it's price!

by Zero, Verified Owner from CA, United States Written on April 29, 2021
When you usually see something low in price, one automatically thinks: "There's some kind of trade-off or issue" which was the case for me, but I have to say boy was I off. this thing is amazing especially for the price. handles well, installs easily and is dummy proof.

I highly recommend this, especially for those in dictator states like California.

Poor quality

by Joe, from NY, United States Written on April 14, 2021
I don’t know if anybody else is having the same problem but the couplings on these magazines won’t screw together. Using the provided allen key for the life of me no matter how you line them up I put them together it’s simply won’t screw together. I bought about eight of these and only got about half of them to go together properly
Would recommend: No

CA compliant mags

by Mossberg 590, Verified Owner from CA, United States Written on March 25, 2021
Fab Defense makes great products, these mags are sturdy and thin. Easy to grab and grip. I use these because I live in CA but I would use them either way and recommend them. Plus the deal OP offers on these is great. I own 10 of these now. you can use as a ten round mag or 20. They also function and cycle great no jams or feed issues.
Pros:
  • 20 round compliant
Cons:
  • tool to assemble
Best Used for:
  • AR - 15
Would recommend: Yes

Perfect in California

by RookieShooter71, Verified Owner from CA, United States Written on September 28, 2020
Great product. Easy to assemble and fits great, it gives flexibility of carrying 20 rounds and looks like a regular 30 rounds mag. I have 5 of these now. California only allows 10 rounds magz so these are an option
Would recommend: Yes

Great Add On

by Gary, from TX, United States Written on June 10, 2020
I love this item and for the price it was perfect for me. Tried putting other mags on there but didn't hold on well but the FAB mags fit great. I love the fact that as soon as I open my vault I can get to these mags faster. I do not have to dig around looking for mags, right there in the open. Easy to install. I love this product!
