Tomi Harley got good things on how ViperTech keeps on evolving its gas blowbacks... "I love how the Airsoft gbbr Vipertech  Company keeps improving their products. You can see how they really care to give you the best product they can. A few years ago there was a little issue because they had a batch of bad materials. But now I think everything is back to normal again and I haven’t heard any bad news yet. We need to keep in mind that quality control fluctuates, we have seen a huge issue with GHK but hopefully with their new generation of Ak’s That would be all solved. I wish Vipertech would manufacturer  an AK variant.

Vipertech is a family owned business, they really care for their brand and what it stands for. High quality and longevity. They are very kind and even sometimes when I order from them parts they would send me some extra parts as gifts."
