Question on M16

SpecOps87 SG

I'm curious, can somebody educate this on me. Lets say I've locked and loaded an M16, the dust cover over the ejection port will be open.But say, I close the dust cover, with a round in the chamber, and i fire off, be it in SEMI or AUTO, will the weapon still be fired?

Thanks

RvnRooRon84 SG

Yes it'll still fire...

When the bolt-carrier moves backward to pick-up another round from the mag, it'll automatically move a latch of the dust cover to make it open so as the expended round can come out..

Yes, I know it is a stylish phrase that GI always say in Vietnam War films.

But "lock & load"?

Doesn't one co.ck weapon first BEFORE putting to safe?

gary1910 SG

Actually it suppose to be "load and lock" and was meant for another weapon, M1 AR.

Read abt it here:

sir sickolot II SG

agreed you have to c o c k yr weapon first, only then can u put to safe ( or change modes)

lock and load is just a term...

R3SsH|n SG

confirm discharge la...
if not how...chamber explosion mehz? Laughing

SpecOps87 SG

No lah...what I meant was, is it possible for the weapon to eject the expended round's cartridge and load in to the chamber a fresh one from the mag, given that the dust cover's closed.

R3SsH|n SG

yes it is possible.
when i did technical handling, they didn't say cannot close dust cover with the danger of exploding. in fact they wanted us to close dust cover whenever we finish stripping the damn rifle. Laughing

the moment the bolt moves across the dust cover area, it will pop out.

When the round is fired, the bolt will be pushed back. Even if the cover is up. the moment the bolt moves backwards, the dust cover will flip open then the round is ejected out. Anyway, chamber explosion is not because of this.

If you never handle the m16 yet why worry?

I thought nowadays all the new recruits only touch the sar21 now? Lucky people then can play with the m203/m16.

not like my time

SpecOps87 SG

Nah, not recruit lah. But cuz I see some naval divers posters/pictures, they show that they emerge from the water in the surf and at the ready with their weapons, and the dust cover close.Thus I'm wondering if its even possible.

R3SsH|n SG

chamber explosion is when 2~3 rounds hit each other when one of the rounds get stuck in the bolt right?
since the run can't be discharge, the gun powder within the round will cause an explosion?

moca SG

Definitely possible to co.ck and then close dust cover. I used to do it all the time. In fact, it is highly advised to close your dust cover after cocking to make sure less dirt get into the mechanism.

Do you think Eugene Stoner would design a dust cover that will cause explosions?

Ah Cek SG

the dust cover only closes with a soft latch. just a finger nail can open it liao. so definitely no problem in expending the empty rounds.

CM06 SG

no lar that is double/triple feeding heh. That's when your whole gun will jam and you need to clear.

chamber explosion as the name states..is the round explode inside the chamber IE outside the barrel. This happens when the bolt got problem and cannot lock in place when it "chambers a round in" ...so the explosion blows backwards into your face instead of forcing out the projectile through the barrel(bigger hole short distance).

Another reason can also be the firing pin is too long and detonate the primer(fuse cap) before the round is completely inside the barrel area.

It's quite rare lah...You kenna means you very sway and can mean needing comestic surgery to look like Andy Lau liaoz.

1.m16 loaded and ready.
2.dust cover closed.
3.trigger pressed
4.projectile flies out through the barrel
5.as the projectile flies out, the bolt carrier moves backwards and dust cover opens.
6.empty cartridge gets ejected out through the open dust cover
7.new round is loaded into chamber as bolt carrier slides back to original position.
8.dust cover still open.

Xcert SG

dust cover closed...cartridge fly out from where?

chamber overcrowded lar... Laughing Mr. Green

beavan SG

no it's possible, the cartirdge / bolt will push open the dust cover before the round actually gets ejected.

|-|05| SG

all it needs is for the bolt to move abit then the dust cover open liao.Like when u half or even less c o c k your weapon it pops open.

Xcert SG

ya lor...must have an open dust cover for the cartridge to fly out.
