Best laser sight for this gun?

Jim, you are probably going to want something small and compact since you plan t mount it on top rather than below (no issue mounting upside down on top). budsgunshop.com/catalog/product_info.php/products_id/714015280/utg+bull+dot+compact+green+laser ----

Jim, Any laser you can get mounted to have quick access to turn on will work. The top rail is ideal for mounting a light or laser. I would recommend a light before a laser. Mount both.
