Improved accuracy
So much better than the orange ramped sights. My old eyes could hit the target when they were all over the place before. Highly recommend. Easy to install, i used a cordless drill, went half way through and then loosened the chuck a bit so it spun when it grabbed instead of breaking the bit. I've done tons of drilling & tapping over the years and with snap i bits it's better to let it slip when the drill grabs rather that have it break the bit off. Take your time, hold everything tight in a vise and it'll be fine
