One on the EE out of Vancover .. used Generation 2 .. $250 and has the 2x magnifier ..
2x magnifier allows for old farts like me to take the fuzzy out of the reticle if needed.
Gen 2 has the exposed adjustment measurements, but allows one to screw in the magnifier, also has the older reticles ( not a biggie )
Seller was not shipping when I went a different and more expensive route.
I want to have a unit in place for April so here is one way to do it ..
I run guns dot com .. unit $173.00 US $25 shipping duty
I run guns dot com .. 2x to 5x magnifier $173.00 etc. They do not stock the flip to the side mount for the magnifier, nor do they have the 2x screw in unit for sale.
RedWolf airsoft UK ( actually china ) sells the HD7 $249.00 and the 2x $59.00 . DHL Shipping ... In stock for both ..
My research does not indicate that they are selling knock off units, I did not find any indication of this practice online .. company is HQ, ed in the UK and conversations with them indicated they use the China location for ease of world wide shipping .. I have a 2x magnifier enroute as I type , but not experienced to know if an OEM part .. do not have the optic from I run Guns yet .
Spoke to I run guns guy on phone sees no problem with HD7 to Canada .. now in his hands , fluked the direct link to his cell , seems he is hard to reach.
Had I not ordered the 2× before the EE sale switched to shipping, I may have just gone there for the win, PM's with the seller woud indicate he is knowledgeable and trust worthy .. JMHO ... but I buy from China
Have fun
EDIT: 2× arrived today DHL , from China ..... had a bit of duty at the Door, but genuine Lucid 2x ( now up to I run guns )
