I finished my Pistol build this week and finally got out on Sunday afternoon for a range test. DPMS Lower (purchased from R-Guns Firearms) DPMS Kitty Kay Upper w/ RRA Bolt (purchased from from PK Firearms) The shooting went well, for the first 40 rounds. Then I had a series of Failures to Extract - three in a row - which lead to a pair of double feeds. Total of about 45 rounds expended. The weather was cold - high of 15 degrees and freezing rain/snow throughout the day. I was shooting as the temperature declined so I wonder if the lubrication gummed up a little. I was also limiting my cheek contact to the buffer tube due to the cold. I've now added a D-Ring to increase my extractor power. Hope that fixes it! http://www.grandgeorge.com/images/ARPistol-Dec07-640-2.jpg http://www.grandgeorge.com/images/Range-Dec07-370w.jpg The freezing cold range Thanks to all the posters on AR-15.com - this was a big part of my success in this build. |

Looking good!! What the heck is that white stuff on the ground? Looks like the beaches down here. +1 on the tube replacment. Try taking your drill and putting it on a barrel cleaning rod with a chamber brush and run it forwords and back words a few times to smooth out the chamber just a little and see if it helps some. Gator. Gota love them AR15 pistols!! Most fun you can have with your pants on.
