Conditional recommendation - Unity Tactical FAST FTC 4X Magnifier

Friend has one and I was impressed with optics and how it center folds. Purchased for a new AR build and have high hopes. The “conditional” part of my recommendation comes from just unboxing the magnifier. A small spring on the arm holding the optic popped off. Was lucky to find it. Now, just hope I put it back in the correct way. Will update review after install and use.
