Great for most people - Geissele Ultra Duty Mag Release Button

First off, the button is very well machined, amazing to touch and worth the price increase if you’re looking for quality. But, if you are getting this button to work with the Hogue Freedom Fighter, it will NOT work because the button is slightly smaller than milspec (Hogue FF requires milspec). Geissele didn’t specify it was milspec so not a knock against them. But since it’s smaller, it still allows you to release mag with upper and lower together. I ended up going with the Strike Industries enhanced mag button, which doesn’t feel as high quality but works perfectly with the freedom fighter kit. TLDR; if you’re looking for quality, the extra cost is worth it. If you’re looking to use with the Hogue FF, it will not work as it’s slightly smaller than milspec.
