What is the procedure to get these parts to align perfectly? Thanks. Pete. |

I have a couple of rifles, gas tubes are straight. If I remove the bolts from the carriers, and the charging handles, I can slide the carrier keys right on the gas tubes. The issue is, that the rifle that occasionally jams, a Bushmaster, I can feel when the key is sliding onto the gas tube. Holding the upper reciever muzzle down, the weight of the boltless carrier is enough to slide all the down on the gas tube. Pete. |

Quoted: I can feel when the key is sliding onto the gas tube. I had one rifle with an oversized gas tube. Boltless carrier wouldn't drop completly into the upper even when vertical. Took a while to track it down, but the rifle would still function 100%. Can you describe the jam in detail? |

The jam is a failure to feed. I haven't really looked at what has happened when it was happening, because I go into an immediate action drill, smacking the the bottom of the mag, then pull/release the charging handle. At this point, I have two cartridges really gumming up the works. I was thinking that somehow the carrier velocity was being hindered. I have had this occur using four different magazines, that previously worked in the rifle, and still do in a FA upper. Pete. |
