Helpful Positive Review solid sight by Easy going, December 16, 2020
Solid sight when wanting or needing something a little different than the rest. Open view allows for multiple ways to view targets differently/improved than standard iron sights. Fun if you enjoy trying something than standard cookie cutter set up.

Most Recent Reviews ultradyne front sight post by Lbraley56, Verified Owner, May 28, 2024
Haven’t been able to test this out at the range yet however upon receiving the product and doing a cursory look at it through a carry handle iron sight, it seems like it will be very effective for its purpose and a pleasure to use.
