it is a 1x magnification red dot type of optic, it uses those small hearing aid/watch type of batteries not the cr 2032 that all those "cheap optics" use.
being it is a vortex i suspect it has some very good glass and will be very good optically. it also has plenty of adjustments for W-E-
vortex has the best warranty in the optics biz bar none.
PA sells a "clone" of this that is pretty good for about 1/2 the vortex price. it has more options on the sight picture like circle dot cross 3-moa 5 moa ect--
the PA comes in red only. the vortex has red and green --i have kinda been spoiled to the green option over the years.
that vortex is sometimes found on sale for about $160. +/- now i don't know if it is made in china or the PIs
i keep saying i am going to buy one --but my eyes have shifted so i like scopes with "fast focus".
i think it is worth buying if your in the market for a dot type of scope that can co-witness with irons.
i have the PA knock off --the PA is very good for the money --i just suspect the vortex is better even thought it costs a little more.
