So i have a UBR with a carbine spring and H2 buffer installed on my lower. I just got Infidel upper today and put it on my lower. my problem is the bolt will not go back far enough to hold open. Its real close but just not there. Any thoughts

Manufacturer of the buffer, spring and BCG? Any chance that the UBR is a fake and not a real magpul?

only things that pop into my mind at the moment.
