Anybody wanting to have a gun dipped might consider the option of just buying a hydro-dip kit and doing it themselves. You can buy kits with various camo patterns online (roughly sixty bucks, or so, last time I checked). The kits have all the necessary materials needed for a DIY project, (except a tub, water, and masking tape). You get plenty of camo material to dip a gun, and perhaps another if you are frugal with the material.
There are a number of YouTube videos showing the process. Once you have a feel for the steps involved, the dipping process doesn't take all that long. If you are a DIY sort of fellow, you might attempt it. At any rate, just a thought for those that are into doing this kind of thing on their own. Doing it yourself is likely going to save you a couple hundred bucks or more.
I have only dipped one gun...and it was a bit trickier than the videos make it look. it turned out satisfactorily for me, although there are imperfections in my final product that I can personally live with. On the other hand, if you are a perfectionist, you might prefer to have a professional dip your gun.
