r/LR308

Recently purchased a soda LR – 308 complete lower ahead of Rhode Islands AWB law. I didn’t have enough time to research and bought a DPMS upper front and pins went in easily in the BCG functions recitative smoothly. But I noticed I have a noticeable gap between the two is this going to be an issue? I haven’t had an opportunity to test fire. When I researched online sources said that they did fit take a look at the pics below. Tell me what you think.

Pretty much done, just need a flash light/pad and some back up sights.
Just having fun with her.
