natedavis49686 Posted September 5, 2014 Report Share Posted September 5, 2014 Hello, This is my first post/introduction. I am an enthusiast/hunter/shooter/guide. Ever since my first AR build, I've been hooked! I'm finally starting my first large-frame build, and have a quick question... For a wedding gift, my groomsmen pitched in to get me a lr.308 "custom lower". I purchased a DPMS upper to get this rifle started, but there is a serious gap back by the extension. I know there is always a little gap, but I am concerned with this amount (attached) Is this a lower receiver issue? Or is the DPMS upper out of spec? Thanks a lot for any help or advice on how to proceed! -Nate Quote Link to comment Share on other sites More sharing options...
