Over the years, I tried a number of optics on paramilitary rifles.
Every "el cheapo" I've bought was a mistake.
I am now firmly convinced that if I need a RDS for a fighting rifle, I will hold off and save up my money. For a RDS it will be an Aimpoint or EOTech. For a scope it will be an A.C.O.G.
There are many less expensive optics out there, but I will save for a while and get the best.
If I should ever (God forbid_) need to use the rifle for serious social shooting, these are far cheaper than a night in the emergency room or a funeral.
History fails to record a single precedent in which nations subject to moral decay have not passed into political and economic decline. There has been either a spiritual awakening to overcome the moral lapse, or a progressive deterioration leading to ultimate national disaster.
If you think a strong military is expensive, think about what a weak one would cost
