I was shooting my LE6920 at a training class this week when I had a strange recoil pulse. As part of the drill, I transitioned and finished. I was unable to run the charging handle after coming off the line. Mortaring the rifle only served to increase the jam, and the bolt appeared to be unmovable without a hammer.
I was able to complete the day with a borrowed rifle (thanks Gunslinger).
After getting home I debated calling Customer Service and decided to try to open the rifle myself. I tapped the BCG forward, back into battery and separated the upper. I tapped the BCG back out of the rifle. I couldn’t see the probem even after cleaning the receiver. I decided whatever it was had fallen out and I missed it. I started to disassemble the BCG to clean it and I found the problem. A blown primer inside the BCG - between the extractor and the cam pin area.
Time for a new extractor:
I also needed new gas rings, which I am not sure if that is related to the failure. Ammo was XM193, rifle is less than 2,000 rds. total.
Bumper Sticker Guy: [running after Forrest] Hey man! Hey listen, I was wondering if you might help me. 'Cause I’m in the bumper sticker business and I’ve been trying to think of a good slogan, and since you’ve been such a big inspiration to the people around here I thought you might be able to help me jump into - WOAH! Man, you just ran through a big pile of dog shit!
Forrest Gump: It happens.
Bumper Sticker guy: What, shit?
Forrest Gump: Sometimes.
I had a primer find its way into the cam pin journal of the carrier once and locked thinks up.Played hell figuring out what happened.That was during my tight chamber issue days.
Ive burned up a two 500 round cases of the XM193C and have had no issues.
Has there been popped primer issues with the ammo?
Hope not…Ive got four more cases of the ammo.
Yeap very good to know.
I’ll have to keep an eye ball peeled on the primers.Guess I’ll use the XM193 for the range and get something else for storage ammo.
A guy running M193 in a course we were in, was blowing primers left and right, so many in fact, that he didn’t finish several drills. After switching ammo, his weapon ran fine. He could have had a bad case of ammo, but man was he frustrated as hell. Talk about perfecting your malfunction drills…:eek:
If I start seeing issues like that,Federal will get the ammo back.
Ive been using cheapo Wolf 62gr. for range/blasting ammo and was saving the XM193C for heavy use.Guess I need to keep up with the ammo discussions huh.
Modern pirate,
By chance do you have a lot# and or production date on the ammo to note?
I hear you. That’s what most of us was saying, send that crap back! I’ve been using Wolf almost exclusively for years for training ammo and for classes. My cases of Prvi M193 (Which I have had no problems with) is reserved for a Pat Roger’s course or willed to family members.
I also had stocked up on XM193 years ago, and it’s always been reliable for me…
However, buddy of mine did a Magpul carbine course in 100+ deg weather recently and said that 4 different guys had primer problems with XM193 (primer from spent casing stuck to bolt, new round chambered with the primer sandwiched between it and the bolt face).
For serious tasks such as hunting I use various Black Hills loads,and also have a bunch of partitions loaded up.Thats also my defensive ammo.But I was holding the XM193C in reserve thinking it was 100% reliable…or should I say it has been 100% for me so far.So yeah it was disappointing to read those reports.I’ll just burn it up and use the brass for more partition loads.
Thanks for the heads up on the ammo - I have fired thousands of rounds of XM193 and this is the first time I’ve had this. I don’t know the lot number, as I tossed all the boxes.
I bought this long before the ammo shortage and decided to shoot it at this class, thinking that the ammo would be better than Wolf or other recent offerings. The weather was warm, but not 100+.
it happens
I’ve got 3 cases of recent xm193 sitting and waiting for a class.
