Oleg Volk sure takes damned good photos.

But besides making me look badass, the photo gives you details of the DP28 worth looking. For example, note the front sight; originally the gun was shooting a bit left and since the rear sight is fixed for drift, it is the front one that gets adjusted which was literally done with a mallet. Then you have the ejection port that sends the brass down rather than sideways. And lastly and most interesting is the gas system: If you look right in front of the bipod, you can see that is more like an exhaust pipe coming out of the barrel and sending gases into the bolt down that tube.  The gun is stupidly simple, but that is full auto for you.
