Hi, I have recently purchased. A polymer 80. Warthog,buffer y build and shoot kit. I am brand new to self building and totally turned on to the experience!! Its the funniest puzzle I've ever put together. I am having some serious issues with my build though. I got it all put together, and noticed that when I loaded the clip the bolt was not going all the way back behind the bullet so there was no way the gun would feed properly. I ordered a new heavy buffer from polymer 80. It feeds awsone now. Then I took it to the range. I shoot, and on the second bullet click... No boom. I asked a couple people what it could b. Showed them the dented primers. They said file the firing pin so it hits deeper. Did that. Still didn't work. I was shooting with a kid who was on military leave. He told me that his gun did the same thing back at the base, and he had the armory fix it. They put the right buffer and spring in it... I looked into that and I think that I need a buffer tube for an ar 10. And they gave me one for a 15. I thought the short buffer would fix this. But I think I need the right buffer tube, spring, and buffer. I would b glad to post pics, video of function, anything to get my puzzle working.
Thanks
