I have been looking at these STG's and G3's for some time now and have the money to jump. I was hoping that someone would have input into which one to buy and from where. I cannot afford the DSA version. I was thinking about an STG with an Imbel receiver, as many gunsmiths won't work on one without it. I don't know who is assembling them for the different outlets, like Wholesale Guns, Federal, SOG, and so I am unsure if there is an advantage of one outlet over another. Thanks for the help!
