There you go folks...Skypup just save you alot of money in ammo and a whole bunch of range time!!
Wow i can't beleive that big lense is lighter than the military 3x that TNVC sells. I'll guess ill find out when i drop them on my feet in the heated blind 
ok so lets recap and please fill in the blanks...
Sony 2x $?????
polaroid 4.5x $76.94 with the step up ring. plus shipping amazon
USGI 3X $ 479.00 plus shipping TNVC and other vendors
The 3x is nice and does slide on and off easily, and can screw in. I can also click it in place with the monoloc. I use electrical to make the 3x ring just slightly bigger to hold the magnifier. This way I can take it in and out fast without having to take off the monoloc.
