[QUOTE="undeg01, post: 2931597, member: 26476"] 300 BLK. Can be a finicky beotch. I built 2 identical rifles, one for each of my daughters. One ran perfectly from the get go, while I had to tweak the buffer weight of the other to get it to run properly. I built a 300 BLK pistol and that one just about got the best of me. I adjusted the gas block, changed the gas block, adjusted the buffer weight and changed the buffer spring. Still wouldn't run right. In the end, I drilled out the gas port to a full 1/8" and cut one coil off of the buffer spring, then went back to a standard carbine buffer. Now it runs like a champ and has never failed. I know, I know.... The gas tube isn't even 1/8" so why drill the port out bigger? Because that's what it took to make it work. [/QUOTE]
