I have the PK-A now and I also have the Aimpoint but I don't have a mount for the Aimpoint. I have not zeroed the PK yet but I had the Aimpoint on an AR and it did great. I have read that the PK's are pretty hard on batteries and the Aimpoint adverties 50,000 hrs plus on one battery.

So, my choices are:

1. Keep the PK; sell the Aimpoint and buy a boat load of batteries.
2. Sell the PK; buy a BP-02 mount with some of the money and use the Aimpoint.

Any and all opinions appreciated.....
