Michael Garey's Review of Armaspec B1 Extended Magazine Release

3 minute installation. Works perfectly. The oversized button makes it easier to drop your magazine with gloves or "old fingers" without it being in the way or worrying about dropping the mag unintentionally.
Be aware that this is only a replacement button for the Mag Catch. You will reuse your existing mag catch and spring.
I will be installing the Armaspec B1 Extended Magazine Release on all of my ARs.
Pros:
  • Perfect size
Cons:
  • None
Would Recommend: Yes
