The larger the button, the easier it is to break the post the button is mounted to. This post is welded into the body of the stamped sheet metal latch. If you hit it hard or twist it, it can break the weld and you end up with a shitty fidget spinner.
I broke a GG$G years ago when unscrewing the pad without holding the pad with a wrench. GG$G did replace it for me.
I wish FFT had spent more time improving the latch so that it was easier/smoother to load the M4. They’re set up with a plater too, wouldn’t hurt to have the latch Np3 plated. This added value would make the price point more palatable and would possibly convince owners who already have a GG$G to upgrade.
