Most Helpful Positive Review Must have for short eye relief models.
With the standard mount that ships with the 4x32 ACOG scope my cheekbone was pressed against the charging handle of an ar-15. This mount moves the scope back enough for comfortable eye relief and cheek weld.

No more nose to the charging handle.

As an army guy, I was wishy washy about purchasing an ACOG. The optic is great, but I like my length of pull, thank you kindly. This product was the reason that I finally pulled the trigger on it, and I gotta say it was everything that I wanted it to be. A full 2 inches of additional eye relief makes a huge difference, and then having the thumb screws facing away from you means that the optic will spend less time getting snagged on your kit. This is a must have for all acog users who don't like straining their necks. If you are active military looking for a way to make your life a bit better, take your rear iron sight and put it in front of your ACOG, put your ACOG on this mount, and then mount the ACOG as far toward you as you can get it. You will go from fumbling to get a sight picture to having your eye sucked into a perfectly crisp image of a soon to be dead terrorist.

Needed eye relief

by Memoryspade, from SC, United States Written on April 4, 2022
Just what I needed to get the ACOG moved so my nose wasn’t riding the cocking handle. Just be aware this mount swaps sides on the thumbscrews so I was concerned they may deflect brass ejecting. This was unfounded as the brass cleared the port just fine
