The SI GSR is a tactical light weight, ultra sturdy, inexpensive solution for shooters wanting to add a rear sight to their Glock but don’t want to have to spend a huge sum of money to have one customized installed. It comes with a rail to mount any sight of your choice, screws to adjust height, and a back plate (Back Plate Locking System) to secure the rail and eliminate any movement from vibration.
If you choose to not use an optic, the rail has reference dots you can paint so you don’t have to remove the rail. For the competitive shooter, the rail is also compatible w/ a separately sold ambidextrous charging handle.
In an emergency situation the SI Glock rear sight rail's front surface can be utilized for one-hand cocking to speed up readiness.
(Door way) It works with most solid surfaces...
(Jeans)...sometimes even the not so obvious places will work.
