GrimmTactical out of Warton, but as I understand he lived to WV now, but still takes work. Supposedly there is an ak smith in Jersey City at Caso's I believe. I picked up a Saiga locally and the prior owner had work done by him. Apparently he worked for Kalasnikov when still in Russia. At least that I was told but don't know how much truth to it.
Wars 10s have shot up. Even used I'm seeing them for about 110 beans. I picked up a Pioneer forged in 5.56. Rock solid. The reviews online seem to give positive marks as well. For under 600 in most cases seems the best deal right now.
Common. It's the hammer profile. Most of the AK style rifles I've owned had this issue, some worse that others. See.s common with the Tapco G2 triggers. I've switched to ALG triggers and seems better. My GenIII Beryl/Archers seemed to have e a nice trigger tight o UT the box...no hangup. Can always reprile hammer to match surplus hammers.
