Decided to give the Matech rear sight a go on my new upper. Never used a sight like this, always used MI BUIS on my previous builds. Which setting would you use when sighting in at 50 yards? I have read that sighting in at 25 yards would be the same as 300 yards, which is fine, but I plan on...

I know somewhere, somebody on here was looking to get one of these.. http://www.slickguns...ack-friday-2012
