Avengers 4x FXD Magnifier w/ Adjustable Flip-To-Side QD Mount (Color: Black)

"As purely a cosmetic magnifier, it works well. For actual use of it is where I give it a 4.

They way its designed makes it wobble a bit upon flipping it to use and can possibly have a non consistent zero. However, the slight shift of zero is although noticeable, still manageable and should be able to plink your targets. The eye relief on it is not super great. You will have to get rather close to it to see through it fully.

Overall, I think you should still be able to use this magnifier in games and as a pure aesthetic attachment.
