I have a Like New, ARMS SIR #45 Military version for sale that was purchased, and installed, but NEVER used. It's been sitting on my AR15, in the safe, where it will remain until it's sold - $345, DELIVERED.
It comes with original box and all accessory rails. My needs have changed, and this one is just collecting dust.
Email any questions to email@example.com. I accept MO's and PayPal (add 3%) and will ship USPS Priority Mail upon receipt of funds.
