О чем постоянно забывают многие, включая конструкторов.

"SAR: What was the most challenging part of that project?

Knight: Building a good magazine ranks right up there. Plenty of challenges anyway, and then the military match ammunition, not even the M118LR yet, was thirty-two thousandths longer than SAAMI spec. We built the SR-25 to use original AR-10 aluminum “Waffle” magazines, which I had 10,000 of. Thankfully, I didn’t have to build a magazine at first. When we started to build the magazine, then it became very challenging, how to make the magazine work. The magazine is a part of a firearm that looks to be quite simple, and people think it’s pretty easy and straight-forward, but it’s a feeding mechanism that is dynamically moving and there are so many nuances that affect the reliability of a magazine. Because it appears to be so simple and straight-forward, I think that it’s often overlooked as being as important part of a weapon system as it really is. Very few people spend a lot of time on designing and developing a magazine, and that comes back as trouble later. The event of feeding the cartridge out of the magazine into the chamber happens very quickly. Feeding the round and presenting it to the chamber, and extracting and ejecting the old cartridge case happens in such a short period of time, and it’s all happening at that intersection of the firearm. This is generally right at the throat of the chamber, it’s almost Grand Central Station for interior activity, it’s at high speed, and anything that doesn’t keep up the pace or gets in the way and the system doesn’t work. The magazine has to be top quality and properly engineered or your reliability goes away."
