Screws sized and cut for fitting RMR, SRO, and Doc sights onto any Army Armament branded pistols.
They come in a pair of two.

Designed for models such as DVC-P (R604), Sand Viper (R605), and Alpha Master (R601-3) to name a few.
For some reason, AA decided not to provide end users for screws meant to screw into the mounting holes of their pistols. We had to do their job for them. I love made in China products, don't you? :DDDDD
