I asked about EOTech alternatives a few weeks ago and got some great feed back and i thank you all very much. I personally have decided to stick with a scope and have mounted up with a Simmons Whitetail Classic.
my buddy however is still stuck on the el-cheapo EOtech replicas for his new ar.

i cannot get it through to him, and he should know better, that they prolly wont work for long.
The question i have is will somthing like
this actually stand up to the shock of a rifle. i know that is an airsoft page, its just an example. he has alread tryed to mount an el-cheapo red dot and it now shuts off and turns on with every other shot. that last sentence may have answered my question but, what do you guys think.
oh, his ar is a Stag 16" carbine .223 w/flattop if it matters
here is the exact one he wants
G&P UFC552 Eotech Sand
