Realistic horizontal grip
Aims better than the vertical grip
None for me
Well, there's not much to say about this. It was one of my first upgrades and I'm still using it. It helps me aim and its very easy to install. It's very comfortable compared to the stock vertical grip when you're laying in the prone positon. It also make it eaisier to snap up your marker to your shoulder from a relaxed positon. Another great product from Spec Ops.
If you're into woodsball, I would reccommend this because it is much more comfortable than the vertical grip when in the prone positon (on yer belly). Speedballers might want to try it too.
