Wolf Gold isn't known for being lightly loaded. This is a full BCM upper? What buffer? It sounds like you are getting an occasional short stroke. BCM is known for small gas ports specifically cut to run on 5.56 pressure ammunition. You could probably switch to a 5.56 pressure ammunition like M193 or open your gas port. |

Full BCM upper and lower. The buffer is whatever comes stock in a BCM lower I am assuming.

O-ring extractor upgrade, you need it.

I would go ahead and check it for gas leaks. Carrier key should be tight, gas rings should hold the bolt tight enough it doesn't collapse under it's own weight. I would make sure the ammunition is locking the carrier back every time at the end of the mag. It's possible you just got a couple of light charges in the ammunition. I would guess BCM is shipping with an H buffer. You can check by looking at the front face of the buffer. In the middle it will have a stamping - H, H2, H3 or no stamping for a standard carbine buffer. You can also check your ejector spring. While standing, hold the bcg with the face of the bolt towards the ceiling. Take an empty piece of brass and hook it under the extractor. Use the brass to compress the ejector until the empty case is straight in line with the bcg. Then let the brass fly. It should throw the empty five or six feet. Anything shorter than 3ft and I would replace the ejector spring. If the extractor looses it's grip on the case I would put an O ring on the extractor spring and try again. |

Quote HistoryQuoted:
This is a possibility. A better description of the malfunction might help. Is the empty case stovepiped to the side or is it above the new case? Is the new case on the bolt face or is it under the bolt - being driven forward by the carrier - if this happens it should have two deep marks in the case from the bolt lugs. Quote HistoryQuoted:

O-ring extractor upgrade, you need it. I have pics but using my phone I can't post them now. The spent round would be partially ejected with the live round buried under it. The live round would be just fine but the spent shell casing would have a pretty crimped neck. The BCG is a new replacement from BCM, and I am going under the assumption that is is working properly... my original one would give me a FTE'S every single time on a hexmag and every few mags with a PMAG. My new BCG just twice every 150 rounds... |

BCM 14.5" LW middy upper w/Precision Armament AFAB, AIM nitride bcg. Only 40rds of Wolf Gold through it so far (new build) but those were 100%.

i wouldnt go opening the gas port just yet. how does xm193 or IMI 193 run? as i recall wolf gold was running abotu3100 from a 20" barrel in one report, which is a reduced load from full on 556 mil spec but WG isnt that either so....
and i would certainly put on o-ring under the extractor first and see if that helps. you should be able to find one at the hardware store that fits, i did. |

If you don't have an O-ring and want one, IM me. I'll put one in an envelope and mail it to you.

I'm going to install an O ring that BCM also sent me. I also have Federal XM855 and 193 I can shoot as well and see what happens. 4 FTE's in 300 rounds is not alot that would hinder my shooting, but at the same time it is probably still 4 times too many...

Wolf gold is stout but not quite 5.56. Try some 5.56 for a while and then try the o ring. Maybe after a little break in the new upper will cycle with Wolf Gold... but maybe you'll find 5.56 is what the rifle really wants and if so at least you know now and not when it's failing in a HD situation.

You are in Good Hands here ... 4 FTE is too many as 1 FTE every other Mag is a stoppage and way too frequent for brass. Lubed up OK? That neck of the chamber clean from carbon ? Good luck with that O-Ring from BCM. |

Try a standard carbine buffer. The H is for milspec ammo. The 14.5 middy needs more ass to run the H buffer

Would there be any downsize to putting in that O ring and trying it out ?

The newer bcm bolts already come with an enhanced/stiff 5-coil extractor spring.
If this is what you have, I doubt you need the o-ring too. |

I have a DD 14.5 mid that will cycle wolf poly/steel cased ammo just fine. Any rifle that won't cycle steel cased wolf is defective IMHO, and Wolf gold should definitely work.
I vote for checking gas ring tension. I had a gas ring break once and the rifle shortstroked infrequently. |

It's hard to tell for certain from the pic, but it doesn't look like your bolt carrier assembly has enough lubrication.

I didn't say all weak ammo, I specified Wolf poly coated steel ammo. Tula ammo is outright garbage, and I'd be hesitant to run any kind of commercial reloads through my rifles.

When I got my new BCG, I had to fire almost 100 rounds each session before I had any of those FTE's. The old BCG was giving me FTE's left and right.. I've been using the SLIP 2000 ELW on this BCG. But it always seems after I'm done shooting and I'm cleaning my rifle, so much of the lube just seems to burn off while I'm shooting. I used to use these old Colt branded lube that was more of a paste. (Still have some.) That stuff never seemed to burn off like this SLIP 2000. Still going to install that O ring and see what happens. Looks like installing the O ring is going to make it a litter more of a pain putting the extractor back in the bolt... |

This gun needs to be sent back to Bravo. I have that exact upper and it shoots Tula up through Mk262 like it's going out of style. Including 200+ of WG. You shouldn't need an O ring in a brand new BCM bolt as it should have the upgraded extractor spring already.
Stop wasting your money and time brother. Time to let the manufacturer get this squared away. |

Finally shot my BCM rifle again. I shot 100 some odd rounds of American Eagle M855 with zero issues. I also put some extra lube on the BCG, as I noticed the lube was always burning off on my previous shoots. And for one or both of those reasons, the rifle finally shot perfect :)

I've got similar issues with my suppressed DD MK18 upper. It runs IMI M193 or Federal XM193 no problem, however swap to wolf golf and it's all kinds of trouble. Spent case actually gets stuck in the chamber and the extractor rips the rim off. Happens without fail, swap back to M193 and the rifle runs like a top.
My colt 6920 however runs the wolf gold without any trouble. I just make a point to shoot the wolf gold in the colt and only use M193 in the MK18. |
