After about 5 years of on and off screwing with it..... ....I am finally satisfied with my 10mm AR. I came up with a completely different way to cut the feed cone on the face of the chamber to eliminate the occasional failure of the bolt to fully lock up causing a misfire. I have run it on a QC10 and Green Swamp lower.....but the preferred platform is the new Angstadt large frame Glock mag lower.....Rich and his crew did an awesome job on their new lower.....it works flawlessly with DI 45 and DI10.
Here is a quick video of the DI10....the barrel literally just came off the lathe and got popped in an upper the smoke is coolant burning off..... https://www.youtube....h?v=3MttYVdNwiw
