Oleg Volk sums up Range Day at Shot Show quite well in this article in AllOutdoor.com this week. Check it out; he and Sammy the Dwarf give concise reviews of new and different items on display. Sammy's knowledge of firearms is impressive as are his shooting skills.
We received a lot of attention at the show until the very end of the last day. Zenith displayed the D9-Z suppressor for roller-delayed blow-back weapons such as their Z-5 series weapons, the H&K MP-5, etc. The D9-Z and the Defender were hits at the show. Here's a short video compiled from a few clips on Range Day.
Many thanks to the guys from DesertTech for putting the Defender on their 5.56 bullpup. They were our next-door neighbors on the range. The conditions were pretty cramped that day and having an unsuppressed 5.56 x 45 round go off just a few feet from heads was...uncomfortable. They have some pretty impressive weapons and certainly deserve a closer look.
