I started with a 20 inch BM flat top upper.  Took the barrel off and put the 11.5 on.  It was a little challenging at first but with help from here it all worked out.  The only thing I am missing now is a new B/BC assembly and some sights.  Once I get that I will check the headspace and test it out on the range.

My first AR build and hopefully I will build many more in the future.  

Hay man that is a nice build.

Thanks for the comment.  I'm sure more accessories will be added in the future.  I think pistols are great toys.  I should have went shorter the first time out for a pistol but I might SBR this later.  Most of the parts were bought from AR15.com members.

Job well done. It looks great
