I bought a Wr762 (vz58) by Kodiak defence back in December. About a month ago I had my first opportunity to shoot it. After about 100 rounds down the barrel, my lower hand guard fell out. Upon further inspection I realized that the gas block had slid about 5cm forward. I phoned Kodiak about the issue and was told that if I sent it in, they would simply put a rubber gasket to hold it in place (I don't think he understood what I was telling him, even though I sent them photos and he had them infront of him. Honestly it was terrible customer service and he did not seem to want to help) since then I have gently hammered the gas block into place with a soft rubber mallet. I have not had an opportunity to shoot since then to see if the issue persist. What I'm wondering, is there any way to fix this issue? Or should I send it in for warranty (leaning toward warranty, just a pain in the ass). It was brand new unfired when I purchased it by the way.
