just curious if this seem to be a widespread(relatively at least) issue of late?
http://www.ar15.com/forums/topic.html?b=3&f=118&t=352614
i plan to buy anoth BCG for a backup,and wasnt sure if i should move some other items up on the priority list and give this some time to work itself out(if needed and its indeed a real issue).
hi Jerm!
bah. i wouldn’t worry about it.
i take everything i see on ARFCom with several shakers of salt.
any company can put out a turd, no matter how good their QC is. the measure of a good company is how they deal with that turd.
how has your defender 2000 been treating you so far?
What is that thread up to now, 5 pages? If you will notice he still has not called LMT.
i emailed LMT in regards to getting spare extractors and extractor springs for the enhanced bolt.
i got a reply back in six minutes, literally 6 minutes, not an exaggeration.
even tho mine was a very small order, you’d think i was placing a major government contract by the way it was handled.
knowing ARFCom, it very well might be a Armalite/Bushmaster/Colt (insert brand here) fanboy bashing a brand he doesn’t own. who knows? but it wouldn’t be the first time.
even if its not a hoax, it could be that he got a 6.8 or .204 bolt instead of a 5.56
if it really was a serious problem he would have called LMT instead of posting on the internet.
A 6.8 bolt is the same as a 5.56 bolt, except that the inner diameter has been relieved to fit the larger case-head.
durrr.
thanks for the correction.
i don’t own a 6.8, but i should have known that anyway.
No prob Para9- we all make mistakes.
Exactly. They just like to complain without actually calling up the company and finding out what has happened.
I guess it is much easier to speculate and ASSume for 5 pages than to pick up the phone.
To date, I have not had a single LMT bolt returned for any issue.
Just like every other company in the world, bad products do get out. No one is perfect.

The OP’s poor handling of the situation aside, is anyone else interested in how LMT high pressure test-fired a bolt that wouldn’t lock?
Bolts are HP-MP tested in the white, by hand ala fired by hammer, in a fixture. It would depend on the dimensions of the fixture. If passed moved on to the park line.
didnt know you were over here.
the man who sold me on LMT!
truth is i havent got to shoot it much,last month or two has been crazy…but so far so good.
she’s a beauty…but thats coming from a proud parent so…
thanks all,i suspected this wasnt something i should be too worried about.
One time at Blackwater, there was this one enhanced bolt and carrier combo…
I got an enhanced LMT bolt a long while ago when it first came out. It would not work reliably in any gun I had, with any carrier combination, or buffer combination and using 55gr M193, XM193 and Q3131a…
Just wouldn’t work. LMT took it back and tested it. They told me that the enhanced bolt was designed to work with M855 62gr only, and that 55gr ammo was not up to spec. :eek:
I sold it to someone and explicitly told them what had been found by LMT. That person bought the bolt and used it to great effect with military spec M855.
FWIW, gs430 aka Mike C., is a very prolific internet bash artist. He tried riding ArmaLite for months and months over an AR-10(T) that he had bubba’ed up.
ArmaLite took back his rifle and offered him a brand new one…he still complained for a few months about it.
I’d not place too much stock in what he has to complain about.
So long as he doesn’t contact LMT, he can continue to ride them on this issue. It’s typical agenda-type BS…
He knows they will make it right. He knows that mistakes happen. I didn’t read all 5 pages, but has anyone else chimed in with out-of-spec lugs?
i dont believe so,but i would need to check again to be sure.
I would take it and send it back to LMT for a new one.

Thank God we have rules here against people like gs430.

I just recieved my much anticipated order of uppers and BCG’s from LMT last week. Everyone of the bolts are within spec and fit not only into the LMT uppers but several uppers I had lying around. I call the OP’s post on TOS bunk as if he had a problem the 1st thing to do is call LMT and with their steller CS it would have been fixed without having to bitch and whine about it on TOS.
Naturally; but I’m wondering if this incident (if it’s true) is suggesting that LMT may not be HP/MP testing every bolt. I have no idea at all how the HP testing is done, so I’m quite curious.
Interesting. I figured as much, but assumed whatever fixture was used would mimic the dimensions of a new, in-spec barrel extension. However, I guess I can think of ways a fixture would be set up that would accept a bolt with .011 oversize lugs.
HP/MP testing has NOTHING to do with testing the lugs size. So the answer is yes, they are testing their bolts.

If it’s proof tested, the bolt would have to fire a proof load. Wouldn’t the bolt have to lock up in a barrel extension for that to happen? I believe the thought is, if they were proof fired, the bolts wouldn’t lock and would be culled.
I agree, its not a testing issue, its a machining tolerance issue.
The thread on the TOS is a pile of shit. I’d be concerned that there MAY be an issue but the source smells fishy.
I’ll stand by and see what happens.
