A lot of people have been salivating in eager anticipation for this one (us included). The Magpul PTS Back-up sight is not any ordinary sight, and as you can see by the photos below, they really are handsome-looking things. There's something quite muscular and "beefy" about the shape of this that give it a futuristic, cutting-edge look. Rather than requiring the sight to be manually flipped-up by hand, it has a neat spring-loaded action that will raise the sight into place once you press the buttons found on the side. Of course, being a Magpul product, the quality of this product is every bit as good as it looks, with a durable DuPont Polymer construction that makes this one solid sight. The pack comes with an additional longer screw to raise the front MBUS sight for sniper guns. Magpul have spent some time fine-tuning this product to make it perfect and it's finally here and available.
