Great product, satisfied with purchase - Command Arms TPR15P Dual Foot Sight Rail For AR-15 Black Finish

Attaches with ease to the standard fixed AR front sight. This front sight rails item is made of polymer and has 3 metal screws that hold it solidly in place when attached via the included tool. It seems sturdy and has held up fine for repeated use at the range. Purchased it to attach a laser to the AR. It works great for this purpose, and the laser is close in alignment with the bore axis due to the position. This makes aligning the laser with the point of impact easy. The rails are solid and have enabled the laser to hold its zero after putting several hundred 5.56 rounds downrange. Because it is polymer, it is lightweight. This product is also available made out of aluminum material (and higher price), but I chose the polymer for my purposes and lower cost. Good service from OP as always.
