Typically, the real VSS Vintorez uses 10-round magazines, in order to provide a lower profile when in the prone position. But because the VSS Vintorez is based on the same platform as the AS Val assault rifle, the magazines are interchangeable. Therefore, operators has been know to switch between the 10-round and the 20-round magazines at will. In addition, 30-round magazines now exist for the SR-3 Vikhr in the form of SR-3M, which are also usable on the VSS Vintorez and the AS Val. So now a VSS Vintorez operator has the option to use 10-round, 20-round, and 30-round magazines.
Therefore, in an airsoft MilSim operation, you can load up 10-round, 20-rounds, or 30-rounds in your mid-cap magazine. And there lies the problem. At the time of this writing, Echo1 does not offer a mid-cap magazine for its Red Star IGOR VSS Vintorez sniper rifle. Instead, two 150-round high-capacity magazines are included with the gun. You can buy additional high-cap magazine, but low-cap and mid-caps are not, yet, available.
The idea, then, is to emulate the real capacity magazine with the high-capacity magazines. Based on our testing, the high-capacity magazine should be able to emulate real caps, because we are able to fire off 46 rounds on a full wound. Ideally, the high-capacity magazine should meet these goals, prioritized, when used in this manner:
In this article, we are going to document how to go about simulating the real capacity magazines with the Echo1 Red Star IGOR high-capacity magazine.
Based on our testing, it is entirely possible to simulate a 10-round magazine using the Echo1 Red Star IGOR high-capacity magazine. We have found that 14 BB's are placeholders in the wind up unit. 4 BB's are lost in the magazine well. That totals 18 BB loss.
Therefore, to simulate 10-round magazine, you would load 10 + 18 BB's for a total of 28 BB's. Using a standard speed loader, which load 4 rounds per pump, you would pump 7 times. Yes, it is ironic that you are using a speed loader to load a high-capacity magazine. But if it gets you the result you want...
The end result is spectacular. Winding up the magazine in the staging area, prior to entering the field, works perfectly. There is no BB rattle. The Echo1 Red Star IGOR fires 10-rounds without misfeeding. The magazine makes a little bit of noise do to the winding mechanism, but it's far from BB's rattling in the mag.
Theoretically, with 18 BB's loss, you can simulate a 20 round magazine by loading 38 rounds into the high-capacity magazine. But is it really that easy? The first concern is how to load exactly 38 BB's into the magazine?
A standard BB speed loader loads four BB every time you pump it. So if you pump the speed loader ten times, you loaded 40 BB's. That's two BB's more than optimal. But if you are diligent, you can inject only two BB's during the tenth pump, giving you 38 rounds in the high-capacity magazine.
We tested the lazy theory of loading 40 rounds into the high-capacity magazine. Then we wounded the high-capacity magazine up. We noticed that the BB's hit the mouth of the feeding port after winding 20 times. We proceeded to wind 30 more time for a total of 50 times to simulate winding the magazine all the way up during the staging area. There are a few BB's rattling around inside the magazine.
After winding it 50 times, we insert the magazine into the Echo1 Red Star IGOR and fired off the rounds in semi-automatic mode. After exactly twenty rounds, the gun dry fired once, but proceeded to fire off three more rounds before dry firing. So our calculation is on track. When the magazine has gone dry, there is no more rattling.
Theoretically, with 18 BB's loss, you can simulate a 30 round magazine by loading 48 rounds into the high-capacity magazine. That's pretty easy to do with a speed loader that loads four BB's with every pump; you just have to pump 12 times.
That was exactly what we did for our field test. We pumped 48 BB's into the high capacity magazine. Then we wounded it up to fifty times. There were some BB's rattling inside the magazine after it is wound. Then we proceeded to fire the Echo1 Red Star IGOR in semi-automatic mode until it dry fires. The gun dry fired after twenty some rounds.
That didn't make sense to us, so we thought maybe we didn't wind it long enough. We tested it again with 48 BB's in the high-capacity magazine. This time, we wound the high-capacity magazine 70 time and fired off at our BB trap in semi-automatic mode again. This time, we fired off 31 rounds before the airsoft gun dry-fired. There is no more rattling in the magazine by the time we shot off the last round.
