Looking for some help.  Recently completed my build which has a 14.5" barrel and a 12" Midwest Gen 2 T-Series Handguard.  I have a EXPS3 mounted with a PA 3X Magnifier and I kept noticing a blob at the bottom when I was looking through he Magnifier.  When I flipped the Magnifier to the side, blob was there but not a prevelant.  Come to figure out it was the Mappul MBUS front side, which is currently folded.  Just wanted to see if this was normal?

Yes, it is completely normal. The front sight is blurry because your eyes aren't focusing on it, which is the way it's supposed to be.

Thank you
