The ones I've looked thru had good glass. The Hakko's had either AR-15, or ring mounts. I'm pretty sure they also sold a BDC in .308 that could be installed in addition to the .223 BDC. They also had a range finding reticle, and a "window" on top of the scope to aid in illumination under low light circumstances.
I have no problems with my Colt short scope. I believe that for a while they also came with a range finding reticle.
Now, the only short scopes are cheap Chinese, (I'm awaiting a Sarco order for a variable power short scope), or very expensive ACOG's.
During Desert Storm 1, new Hakko's were selling in Shotgun News for as low as $150! I kick myself for being too poor back then to buy one!
Why the heck did these guys stop production of these scopes? I really didn't want to buy the Chi-com, but the ACOG's are cost prohibitive, and without a removable BDC, can't be installed on other rifles.
I contacted Hakko/Japan, and confirmed they no longer make the short scopes.
I remember soldiers photographed protecting Schwartzcopf, had these on their rifles. Any ideas as to why the manufacturers of quality no longer make these?
