these are both brand new never mounted.i have a barska mounted on my gsg/mp5 .22 knock off and it holds zero good.

i have the same aimpoint mounted on a AR10 and it holds zero.
the m4s has both red and green optics w/glare shield.
yes,im fully aware this is aimppoint knock off but it is the ONLY unit that actually uses real aimpoint parts and holds zero on something larger than .223.
this is NOT for airsoft.this is right at home on a ar/m4
150 for the m4s
35 for the barska
175 for both
