Trying to adjust the front sight on your rifle but don't have the right tool? This little guy is your solution. It's a dual-purpose tool with both a 4-prong and a 5-prong end, designed to fit the common square-front sight posts on many rifles (like AR-15s, AKs, and others). It's made of solid metal, about 47mm (1.85 inches) long, so it's tough enough for the job and fits easily in a range bag or pocket. The model seems to be ZHAT-002. Brand new, made in China. Whether you're zeroing in a new optic or just making a quick windage adjustment at the range, this simple tool is a must-have. No more using pliers and scratching up your sight!
