mostly all Plastic so longevity may not be that great especially if bumped against object or from a drop. But they do work, easy to adjust and sight in.

Decent sights for the price on a budget build. Being flip up makes them worth it. Nice and sturdy polymer

These sights are probably good for airsoft for looks and being "tacticool" but they are pretty bulky in the sense of the footprint they have on your picitinny rail when folded down. The fiber optics aren't really bright and you need to seriously focus through that rear sight to see the front through it. Honestly for the price I get it, definitely if I was younger and needed some flip up sights for a quick game of airsoft id use these in a heart beat, the quality just isn't there for an actual rifle.

No matter what rail I try to mount these on, they do not securely tighten down. The reason for this is simple: the entire piece that interfaces with the rail is one solid piece with a screw running through it. It is oversized and the screw simply keeps it from falling off, but it does not bite down on the rail even once the screw is bottomed out.I wish they were right because it is a cool design. But they flat out don't work on anything, and I have a variety to pick from.Don't waste your time or money. I'd rather have 3d printed sights or a cheap red dot than these sights

functionality

My ZBULAR Fiber Optic Sights, Flip Up Front and Rear Backup Sights are exceptional! They are easy to install, fit great, and the graduations on the rear sight make zeroing simple. The front sight is easily adjustable vertically due to a built-in wheel, and in the base of both front and rear sights is another set of fiber optic sights for close work, meant to be used with the upper sights flipped DOWN. The ZBULAR Fiber Optic Sights are spectacular, and are a bargain, and I STRONGLY recommend them to anyone looking for sights for their M4 AR upper.
