More rounds than most can afford.How long before the average AR15 bolt needs to be replace do to lug facture???
I've never had a report of a 5.56 bolt failing but have no idea of round counts on any made in the last 12 years. I shut down the CNCs in 2017 so I don't machine any now. I've had 1 6.8 fail probably due to HOT handloads(customers words). I had 2 Grendel bolts fail, 2 in 6 months were due to an receiver that was not square. I squared the receiver for the customer and haven't heard anything since. None of the 6BRX, 270AR,270MSR 800 series or 750XD bolts have failed. None of the Titan Grendel bolts have failed. To get a number, we machined apx 350 bolts a week for 10 years.Are ARP’s bolts no longer a thing?
Seems like LMT Enhanced bolts don’t break, but are questionable in terms of reliability and replacement parts. Very system specific, it seems...
Rifle length, PSA, Carpenter 158, MPI tested, Wolf Gold brass case 55gr fmjHow long is your gas system? Who made your bolt and what material is it? What ammunition do you use? Was a proof round fired in it?
this is the first that I heard of reliability issues with LMT bolts
I’m willing to give the LMT bolt a go, if everyone here says they have no issues. Whenever they come back in stock, that is! I also don’t mind stocking up on wear parts as they become available, either.
I’d have to do some digging, but I recall people tracing bolt issues down to the enhanced bolt and replacing with a standard LMT bolt, a Colt, or BCM/DD and issues went away. I don’t think it was on this board, though, meaning it could very well be the blind leading the blind.
I can’t imagine why a bolt made of improved material would be useful...

1. You'll know when it breaks.How long before the average AR15 bolt needs to be replace do to lug facture???
Carrier, The carrier is what delays the unlock the bolt just rides along. The bolt is made from 9310 and has a dual spring extractor but that does not affect the timing.Check v1 tactical for LMT products.
Also straight from the guys at V1 that have a really
Good relationship with LMT, they were talking with LMT about the EBCG/E Bolt and they said “they don’t know why anyone buys them” they are for a niche style gun and a waste on anything else. They were made for short, suppressed, full auto. If it doesn’t fit that description go with a standard bolt.
Yes for real. Tom Beckstrand former Army Special Forces (Green Beret)/ Sniper instructor graduate of Ranger school andWhen one of the lugs breaks off
Is this question for real?
Do people sit around thinking this shit up? Go shoot instead.

West Point was featured on an episode of Gunsandammo TV that talked about the parts on an AR15 that might fail. Yes he also shoots alot.

Funny, back in the mid 80s I knew a guy that carried a complete spare BCG in his ruck.This question is nearly impossible to answer...literally could be anywhere from 1-20,000+ rounds. There are far too many variables to give any definitive answer. Stick with reputable manufacturers that are commonly known for quality/reliability and have a spare as back up.
PS Gas keys on the Bolt Carrier are also a point of failure. If you are concerned with not having an inop gun, best practice is have a complete BCG assembly as back up....better yet just buy a back up gun.
The ones made by Microbest. Problem will be finding someone who will tell you that is where they get their bolts.@Constructor I got one of your barrel/bolt combos about 10 years ago, in the event either of them eventually go south do you recommend a particular replacement/spare 6.8 bolt?
That is fine for shooting targets and hunting but not duty or combat. You can't hit pause while you go find another bolt of course there is always the sidearm or a pickup. I'm sure it had been back to the armorer several times. The direction of replacing after 4-5000 is so you don't get that "click" at the worst time.When I was Marine recruit, I qualified on a Viet Nam era M16 that probably saw combat, was beat to shit, abused by dozens of recruits before me, and probably had thousands upon thousands of rounds through its barrel. I'd bet that tube was smooth. But everything worked and it was able to hit black from 500 yards and allowed me to acquire a pair of crossed rifles.
Shoot it 'till it doesn't shoot and then decide what to do.
I trust your judgment as you are the real deal-saw combat with the M16 in a life and death situation.

never had a bolt fail and had have that’s got well 10,000 plus rounds on it. It is on my NRA/CMP service rifle that I’ve been using since 1994. It’s a Colt. Just carry extra extractors and springs.
I’d have to do some digging, but I recall people tracing bolt issues down to the enhanced bolt and replacing with a standard LMT bolt, a Colt, or BCM/DD and issues went away. I don’t think it was on this board, though, meaning it could very well be the blind leading the blind.

Anything might fail
I don't GAF what super duper soldiers have to say, bolt lugs should NEVER shear off. If you think that's a maintenance item on a rifle, then get a better rifle.
Sorry to burst your bubble but it is a common failure point. The lugs to the right and left of the extractor break all the time.
