My bushy 20" Hbar short strokes with some brands of commercial ammo, specificallyAE223 and PMC. Works great with Q3131A, XM193 and XM855 which I know are hotter. Called Bushmaster and they suggested carrier key check. The key is tight and staked on. Then they said to check the gas tube where it inserts into the sight base for carbon. The tube has carbon on it for about 2" behind the sight base as does the inside of the upper hand guard shield. This rifle only has about 200-300 rounds through it. Bushmaster then told me to remove the tube and reinstall same with Loctite. I would think that this should not be necessary on such a new rifle unless that's what they do on their new production. Removed gas tube pin but could not extract tube from base. Have since read a few removal hints posted here and will try them. Would like opinion on the Loctite "fix"or should I just get a new tube and install same. Also, could this be a partial misalignment of gas port to FSB problem. Thanks, Moigr |
