Gun won't fire, upper and lower stuck together

[Hoop]

OK I know what your talking about now.

I replaced mine with .075 stainless steel ball bearings. works better from my perspective .

Thanks for the info.

I may do that, also I plan on seeing if I can use small allen screws to put tension on those springs (the rear one at least, I think it was a threaded hole). That way it'll be easier to pull them when I reload & and when I take the stock off the little spring won't go flying down the hallway again.

Never mind, I figured it out. No buffer spring *duh*. Alright, now when I pull the charging handle back I can get an audible firing pin click, however I can't get the bolt to stay back when cocked. Is this normal?

I hate to say this, but I have forgot the buffer spring a few times. That is why that was the first thing I thought when I saw this thread.

Take your upper off.... push that pin 100 times in and out first.... it will loosen in no time...

Don't reinvent the wheel, and don't try to solve something that isn't really a problem...

Try forgeting to reinstall your firing pin. OH whaat fun it is to remove your stock/buffertube to unjam that puppy. ..

The bolt catch/ release should be the only thing that holds the bolt back.

You can do this by placing in EMPTY mag in the magwell and then pull back on the charging handle. The bolt should stay back.

Or

With no mag, pull the charging handle back and keep it back, then push down on the bolt catch/ release.

Does this help?

I think you meant "pull back/ away"

I've had this delightful experience myself

I'm trying to imagine some soldier in the field fuggering around with his gun and having one of the 2 dozen springs that are in the lower go flying off into space.

My personal favorite was the spring that holds the front disconnector thingamabob, that sucker was fun.

Regular soldier's field stripping, NO springs should be flying around!

I recommend a read of page 7-25 of the M16A2 Op Manual, TM9-1005-319-10

The ONLY spring that you may encounter is the "extractor spring", which should be attached to the "extractor".

NO field soldiers are supposed to dissemble the lower receiver, army armorers do that, if necessary.

My personal favorite was the spring that holds the front disconnector thingamabob, that sucker was fun.

What are you talking about? there should be NO SPRING in the front of the "disconnector". Are you *really* talking about the "disconnector" , or are you talking about the "pivot pin" and its "detent" & "spring"?

When field stripping an AR15/M16 there is only one spring to be worried about, the extractor spring. That one is press fit into the extractor.

Either way works. I push down on the little nub that sticks out on the bolt catch, located below the roll pin.

I think the only good use for the forward assist is to help you get the bolt back in place after getting exicted about finishing a build and forgetting the action spring and buffer. At least that is what I have heard.

Isn't that the ONLY use for the "Forward Assist"???

Forward and rear pivot pins. They're what stop the pivot pins at the 'in' and 'out' positions, and in the Stag LPK's at least, they're kinda pointy, which makes the pins hard to slide. They round off very quickly with use.

Basically, they're the little nubs you put in place at the end of the springs prior to installing the pivot pins. And the ones which folks keep launching and losing. That front one can be difficult.

Then why are all of mine magnetic?

Weird - I was always told they were brass. What company did your LPK come from? I'm gonna be tempted now to go magnet-check the spare ones that came in one of my LPK's.
