RE: apex nitrus 6 pin sight
I've got the Apex Nitrus 4 pin edition and I love it. It's extremely well made, and VERY easy to use. The pins are SUPER bright and each have their own micro adjustment. The sight comes with a LED light for the low light condition. Has a fiber optic ring around the sight to help acquire the pins faster. It also has a screw in allen key to adjust the sight on the fly. I though that was awesome because I always loose allen keys. The gang adjustments are real accurate and crisp and don't ever move. This site has a level built in, I found that using the level has helped my accuracy. If you got the extra coinage it's definetely one of the best sights in my opinion. I would reccomend the 4 pin over the 6, looking through 6 pins is hectic!
