Wireless Model: The Series 4000 Plössl 9mm Wireless
Illuminated Reticle Eyepiece includes a red LED illuminator,
operated from internal batteries, with variable brightness
control; batteries are included with eyepiece. I've only used this eyepiece 2x. And the reason for selling is that I don't care much for the X,Y adjustment. It's in excellent condition and as stated above I've only used it 2x. These sell for $149.95 but this one can be yours for $110.00 including shipping in the USA only. I'll accept PayPal, Money Orders, Cashier's Check and Personal Check (Must Clear First).
