good alternative to magpul polymer offset by Jay, Verified Owner, October 13, 2024
This has one more slot of rail space and is more rigid than the magpul offset rail, and is not as tall as the magpul one, not that the magpul one is bad. But if you need a little more rail space and rigidity, this is the way to go.
