Question: Is it look-through?
Document: This thing is machined well and looks good too. If you don't need a &#34;brand name&#34; riser for twice the price you can't go wrong with this one. I would buy it again if I needed to.
This is the second riser that I purchased from B-Square. I bought the first one without reading the description and made my decision based on the picture alone. The picture was the same as this one, but the riser was only 2.5 inches long! They allowed me to return it for a refund with no problems. I purchased this one and couldn't be happier! It's rock solid on my rail and I like the allen head bolts that it uses for attaching to my rifle.
This is a nice little rail riser. My only wish is that the height would be advertised. I was hoping it was 1/2 inch, but it is more like 3/4 inch. Otherwise, the construction seems good. I especially like the small hex nuts as opposed to the large head round screws that so many rail risers use. I plan to use this more as a permanent riser, so the smaller hex nuts are a definite plus.
RECEIVED MY RISER VIA THE MOST DIRECT METHOD. THIS ACCESSORY TO MY AR-15 IS OF TOP QUALITY  AND MEETS MY NEEDS TO A "T". MY SCOPE AND FLIP UP REAR SIGHTS FIT PERFECTLY. THANKS A MILLION!!! !
