Young Manufacturing (Y/M) AR15 5.56 pistol upper 7.5" (1:7) with Y/M bolt, buffer tube and spring. Can be used without a buffer when using the 4" buffer tube and carbine spring. Using this buffer tube, the length is just under 22". The last picture is for reference only on how I had the upper set up. As an FYI, you can use a "brace" (KAK brace in last picture) to shoulder a pistol and you are 100% legal (per BATFE). Additional info on the bolt and buffer here .... http://www.jsesurplus.com/youngmanufacturingchromepistolboltcarrier.aspx
