Kygunco.com usually runs really good deals
I have only purchased on gun online, about two years ago, and it was from Kentucky Gun Co. I was very happy with their price and service.
A "good" online gun dealer is as rare as a "good" tax audit....... Trust me.
Go with local dealer you can build that rapper thing with. You'll come out as good or better after fees and shipping. Plus you'll have a throat to choke if things go south.
Unfortunately, from my experience, there is only one "local" gun dealer I would even consider doing business with again, and that is SSP.
