I have 2 NIB Bushnell Holo Sight 2x Magnification Adapters. Fits model 400 (sku 50-0020 & 50-0021) They are perfect NIB and never installed. These are the magnification adpters only and not the holosight too. I paid $200 each, but I'll it for $60 shipped or $110 shipped for both. I also have two more that are used but very lightly and have the box and papers. I'll sell them for $45 shipped each or $75 shipped for both. I accept paypal, checks, and money orders. Email me for pictures. I'm open to trades so email me with what you have and we can work out a deal.
These will only work on first generation Bushnell holosights. They won't work on eotech second generation holosights.
