The RMS2 is small enough to fit discreetly on any gun, tough enough to withstand the harshest recoil and light enough that you won't even feel it's there. Machined from strong aerospace-grade aluminum, the RMS2 features super-fast automatic brightness adjustment to adapt to your environment, allowing you to focus on your target. By removing the battery drawer from the original RMS, we've enhanced the overall strength of the sight and incorporated new electronics for a clear, best-in-class shooting picture. Its sleek, low-profile design makes it perfect for any custom pistol build. Additionally, our matching low-profile Glock MOS plate allows the RMS2 to sit so low that it co-witnesses without the need for suppressor sights, all at a highly competitive price.
