Almost returned, but modified instead. - Bastion 5.56/223 AR Threaded Trigger Guard

I don't understand why they would send 3 screws, when it should use all 4 points. To make it worse, the one longer screw didn't even fit the included Allen key. I almost returned it because of this alone. They also missed an opportunity to match the angle on the infamous trigger guard gap. (It is partially filled in, but could be so much better.) I had to buy 2 screws to install it correctly. (3 mm x .5 mm thread pitch x 6 mm button cap hex head screws)
