I saw that Wes is selling full auto bolt and carrier groups with the Crane extractor mod for $250. I did a search but came up with nothing. What is modified, and what does it accomplish? Thanks |

Quoted: IT'S NOTHING MORE THAN A SIMPLE, HEAT AND SOLVENT RESISTANT O-RING. IT FITS OVER THE EXTRACTOR SPRING AND PROVIDES MORE RELIABLE EXTRACTION. "WORKS FINE. LASTS LONG TIME." WHY DIDN'T YOU JUST ASK ME? WES GRANT [URL]MSTN.BIZ[/URL] Thanks Wes. I figured you'd be one of the first to answer this. [:)] The reason I didn't simply ask you is because, after doing my fruitless search, I figured it would be best to start a thread with a searchable title for others to find in the future. I thought that this might be a newly designed bolt with the extractor and spring in a different configuration so that centrifugal force doesn't fling the extractor open anymore. Can you tell what the inside diameter, outside diameter and thickness of the O-ring is? I ask because I did this mod to my extractor about 2 years ago with a 13 cent ring from the hardware store. It throws the brass at about a 45 degree angle behind me and I've been starting to wonder if the o-ring is too thick. BTW, I clean my bolt with brake cleaner and after X-thousand rounds and several cleanings in the last two years, the O-ring still looks brand new. |

THE CRANE EXTRACTOR MOD IS FREE. WE INSTALL THEM IN ALL SPR AND FULL AUTO BOLTS WE SELL. THE COLT M16 FULL AUTO BOLT CARRIER GROUP IS WHAT COSTS $250. CHECK OUT THE PRICE FOR THE SAME UNIT AT S.A.W., THE ONLY OTHER SOURCE FOR THEM AT THE MOMENT, AND YOU WILL SEE THAT $250 IS A GOOD PRICE. IN OUR SEMI SPR'S, WE PREFER THE LES BAER CUSTOM HARD CHROMED BOLT CARRIER. IT IS THE SAME AS FORMERLY MADE BY YOUUNG MANUFACTURING. PATENTED, IT IS THE ONLY SEMI CARRIER THAT WEIGHS IN AS HEAVY AS AN M16 FULL AUTO CARRIER. ITS WORKMANSHIP IS FLAWLESS. YES, IT IS EXPENSIVE. WES GRANT [URL]MSTN.BIZ[/URL] |

Crane made a presentation last week in Kanas City about their successful 10" CQB Carbine program. They briefed a new "5-coil" extractor spring in lieu of the standard 4-coil. They did not mention any "o-rings", but did say the 10" upper incldes the "one-piece coil gas ring", and it looked by the test data they were replacing gas tube at about 5,000 rounds. ColdBlue was there... |
