I would recommend you just grab a Bushnell TRS-25, save for Holosun or a Vortex.
Those replicas are horrible, and 90% of them don't last even a year, and are not GBB shock-proof.
My personal experience of course, YMMV.
RE: Bushnell.
They go on sale here and there, you can picked them up semi-new on Canada Gun Nutz for like $100 bucks.
