| has anyone had any problem with their bushmaster xm15 jamming? like the extractor was bad but it wasnt. mine is brand new out of the box and cant shoot two rounds without jamming. i was shooting the winchester 223, and pmc. then a guy at the range was nice enough to give me 5.56 and ss 109 to try and there were no problems after that. what would you say, crappy ammo? i'm hoping thats all. |
Did you dissasemble and clean it before you took it out and shot it? New in box does not mean clean and ready to shoot. Every new rifle I get, is taken apart, cleaned and then lubricated. Most new rifles are dirty and have small pieces if metal left in them from the milling/assembly. If you did, then it probably just needs more lube, and a breaking in period, and yeah ammo does make a difference in operation. |
| it jams by the empty cartridge staying in the chamber and the next round loads underneath. i brought it back to the dealer, he put a new extractor and rings in for me. went back out on the range, started jamming on the 2nd clip and every round after. it seems to work fine with 5.56 or ss 109. |

Sounds like you need to break it down and clean the heck out of the chamber area, sometimes oil left over from milling stays in the chamber and turns to laquer, the 5.56 is loaded a little hotter so it will extract, while the Winchester white box .223 isn't quite strong enough. I had the same problem with an old Commander barrel, it would get worse as the barrel heated and the laquer became "sticky" from the heat. The extractor would actually tear a piece of the rim off. |

It's not a gas problem, how can it be a gas problem when it has enough gas to have the extractor tear through the case head cycle back far enough to pick up and try to load a new round? There was no reason to replace the gas rings, since that fixes gas problems, This is a problem with sticky or undersized chamber. Take a hand drill buy a 1/4" diam brass rod, split the end of the rod with a dremel or hacksaw, slip a piece of green scotch brite in the slot, now insert into chamber and run drill for a bit both directions. This will nock loose what is sticky in the chamber, Now buy yourself a Wolf extra power extractor spring. Now shoot the gun, if it does not work then find a brand of ammo it likes and be happy. |
He did not say it was tearing thru the rim. Nevertheless, it does not sound like insufficient gas. |
| I think your best bet is to call Bushmaster and get an RMA number. Let them go through the trouble of fixing the rifle or at least ask them for suggestions over the phone. I would not go mesing around with drills and such even if it could fix the problem, as there is the potential to damage the rifle and create new problems. I would also be leary about voiding the warranty through any at home efforts to fix it. |
+1 and AMEN to that. Hineline's suggestion sounds worthwhile for a home-built. Even if he's 100% dead-on I wouldn't waste my time and energy on a new rifle I payed a premium for. Bush has good customer service and I am sure they will resolve the matter if it's still screwy after you have properly cleaned & broke the rifle in. |
Damn good advice.

+1 DO IT! |

i shoot like 200 rounds brand new from the box my barrel turn orange and there was orange stuff left on it went home clean it well but when i try to load it gets jam it looks like the ammo is not going into the barral correctly call up bushy and they think i have a had mag but i'm sure i don't what should i do |
What kind of magazines are you using? What do you mean by "jam"? |
|
So did it shoot well after you cleaned it? How many magazines do you have and what brand are they? Did you clean the rifle per the manual and what type of Cleaner/Lubricant/Protectant did you use? After how many rounds did the barrel turn "orange"? Where did the barrel turn orange? How long did the barrel stay that color? Was the barrel very hot to the touch when it became orange? Could you hold it with your bare hand for more than a second? Did you continue to shoot when the barrel became that color or did you let the barrel cool? What do you mean by "Jam", exactly. Does the spent brass stay in the rifle, the next round not get picked up from the magazine, do two live rounds wind up in the weapon at the same time, one on top of the other....please be specific. |
I second this. I emptied five mags through my Bushy right out of the box, no cleaning, no lubing, no shit, and fired flawlessly. I did use a mag I new was good from my other ARs and of course then took it home and cleaned it. Tj |
+1 This is not a garage gun. |

medalhedd, Send it back to Bushmaster to fix. I had the same problem out of the box. I cleaned my rifle and took it out to shoot. The problem was the spent shell would not leave the receiver causing it to jam as the bolt picked up a new round. Using only 1 rd per mag the bolt would lock back but the shell would still be in the receiver. I was using Malaysian M193 and AE .233. Same problem with both ammo and a mix of USGI mags. Took it home and cleaned it again. Next trip out I had the same problem. If I used the bolt and carrier from my Colt, it worked fine. I sent it back to Bushmaster. They fixed it. My packing slip stated "sealed gas system". All I could tell is they restaked the gas key. I only have 350 rds through it since I got it back but did not have any failures. I used the same ammo and mags to test it. Turn around time was one month over the Holidays. Give Bushmaster a chance to fix. That is what the warranty is for. |

Same thing with a new "restricted" Bushy 20" HBAR I believe is a 2002 manufacture, but only short-stroking with Wolf 55 grn. Malaysian M193 and PMC 223A/D (5.56 marked on camo box) worked fine. I cleaned and lubed right out of the box before shooting. Carrier key is good so I thought I'd give it a couple more tries before getting too excited. It appears some Bushy owners are having/have had your experience and hopefully more will chime in and get you squared away. Scott |

If I were you, I would clean the hell out of the chamber before doing anything else. Dump some CLP in there, and use a good chamber brush, and spend 15 minutes scrubbing out that chamber. You'll get it clean and slightly pollished (not as much as if you were using a polishing compound or shot a few hundred rounds); it may speed up the "break in" time. If after that you still have trouble, then send it in. Seemed to work for me on a new BM barrel. rvb |
Thank you. EVERYONE has problems from time to time. It was assembled by humans. Sounds like a gas problem if it cycles ok with the full power military ammo. I am the proud owner of two non-problematic Olys. Not gloating, but its time people realize there is no perfect manufacturer. |
+1. It (for example) it's an undersized gas port, it would work fine with military pressure ammo and some civilian loads, but it might not work for some lighter civilian loads. This is not uncommong for some makes - but even the 'big' guys will have lemons slip through ( at almost 40,000 ARs a year there are going to be mistakes). Call Bushy and get it fixed. |

Very interesting... I experienced almost the exact same issues with my Bushmaster "M4". It was like the chamber was gripping the cartridge & the extractor was ripping off part of the rim trying to extract it. The chamber is chromed, and was running fine for a couple of trips to the range, that's when it started happening. I was shooting some South African stuff - I changed to other ammo (various types) and never had another problem. I suspect that lot of ammo was not in spec (about 70-80% worked ok, so I think something was drifting out of tolerance on the mfg line?). After trying the different ammo & it working fine, I tried the SA again - it starting jamming frequently. Pretty much narrowed it down for me. |

I know every rifle is different but an AR that is in spec and built right should work with most ammo out there that's dimensions are correct, even if it is lightly loaded like Wolf. My Bushmaster eats everything from SA, to Winchester White Box, to Wolf. It does not require XM193 to run and neither should yours. Try some different mags and the other suggestions here. If you still have problems then call Bushmaster. It could be a problem on their end. Fortunatly they are a great company and will take care of it for you. And yes, all companies let one slip by, but I am a little surprised by the number of people that have spoken up in this thread with extraction problems. Are these specific to recent rifles or spread over several years. |

gvidon, Since you asked, I believe mine was NOS that I helped a distributor free up warehouse space when I purchased. I think it's NOS due to the 02 date on the mag and the 2002 catalog in the case. If someone has a serial number range I can be sure. Serial number is L291XXX. Scott |

My BM Type 97S (GASP!!!h.gif) is at the factory right now for the exact same issue plus one more. I think the barrel (FF) is somehow cocked on the upper (because it was impossible to sight it in under 4" left at 50yds). I too am looking forward to anymore posts... |
