Most Helpful Positive Review Pretty Good Product
I installed this on a Larue lower. It make ejecting the mag much easier than the stock button. It does stick out a bit far from the receiver and could be bumped on accident cause an unintentional ejection. I wish it was half as thick and made of steel or titanium. Overall I like the product and ...

Most Helpful Negative Review Way Too Big
This thing is just way to big, it sticks out way too far from the side of the rifle & it fits a very small amount of lowers. The quality is good but fitment and practicality just isn’t there. I’d recommend the Magpul over this thing any day.

my favorite mag button

by Jayel Dubya, Verified Owner from AL, United States Written on July 26, 2025
Pretty much perfect in size for me. Feels good resting my booger hook on it when not in the trigger guard. Bring your own loctite.

We’ll designed

by Jeff, from FL, United States Written on October 1, 2022
A quality, well designed extended magazine release. I had to replace another custom magazine release on my lower because it was hitting the anti-walk pins. The result was that I couldn’t get a mag to release most of the time. The Armaspec clears the pins, is much more solid when depressed, and the mag releases 100% of the time. It’s also solid and looks great. Easy to install with new screws that are provided.
Pros:
  • Looks great
  • Excellent design
  • solid material
Cons:
  • None
Best Used for:
  • AR Lowers

Large mag release button.

by Hawk, Verified Owner from KY, United States Written on March 15, 2021
This is a great mag release. It's easy to use if you have coupled mags or a Beta C drum mag. Lefties be careful, though, you'll drop your mag if you tend to rest your rifle on your mag pouches. The material is aluminum, even though the pics make it look like polymer.
Pros:
  • American made Allows for quick mag changes.
Cons:
  • Lefties might need to change tactics
Would recommend: Yes
