I received the BDS-37 with the KeyMo adapter. The quality speaks for itself…SOLID! The installation was ridiculously easy….I thought maybe I did it wrong, cause it could not have been any easier. The design is nice and It looks fantastic.I have not gone to the range to shoot with it, but I am certain this product will be just as good as any other JMac products I own. The price is definitely up there…no doubt that it’s not cheap, but thankfully I can afford it. Price not withstanding, I give it a 5 stars
