So I am looking for some help in fixing an AR problem I am having. The bolt in my DPMS AP4-308 is not locking all the way back, so the Bolt-Catch is not "catching the bolt". It is about 1/3" short of where it needs to be. There is no obstruction in the stock spring and everything appears to be put together right, but it is obviously not. When pull the charge handle back it feels like it is going all the way back, but something is not right. I hope that I am just an idiot and it is a quick fix. Any ideas? Any suggestions on a local shop to take a look at it (Tigard area)? Thanks.
Jon
