Question about C7 malfunction

Or ask someone who uses the damned things for a living.

Blanks require a plug at the end of the barrel so the bolt will cycle. That leads to all sorts of s**t flying back into the weapon's operating parts and tends to gum up the bolt pretty good. I mean, I've had a C7 so badly fouled by firing blanks (last time I borrow someone else's rifle when they need an extra body for OpFor in a hurry) that I had effectively a straight-pull bolt-action C7 and shortly thereafter I couldn't even manually #### it anymore. That's one gun I had to clear using some violence and that made it's way right to the plumbers the moment we got back in garrison.

And the problem in that video looks like a mag issue to me. Since he says the "router", which to me I think is the follower, is crooked, maybe it's an issue with the "clips" holding it against the spring being busted. But that's just my guess.

I figured that one who "uses a C7 for a living" would at least know what is going on with his weapon.
Blanks do not send any more
"blow back" than firing a live round, the BFA doesn't seal the barrel it just retards (much like the above comments and the user on the clip) the gas enough so that some can go down the gas tube and function the weapon, in effect taking the place of the bullet. You get more stoppages with blanks for 2 reasons:

#1. The blanks are shorter that live rounds and have a flat face compared to a bullet, the get hung up when being forced into the chamber causing maffunctions;

#2. Most idiots on the trigger do not bother to properly lube the weapon, or insist on firing blanks like an idiot burning off any lube, crap only builds up on a dry weapon.
 
Blanks

I've been shooting blanks in the military since 88. I've had my share of jams but in the end it is either a loose BFA or crappy mag as there are lots of those in the military.Out side of that the C7 will function very well with them.....People in the military come up with strange rituals just the same to compensate for the perseived problems anyways...."your gas ring are aligned so the splits let gas through and cause it to jam" (i take apart my bolt and align them on purpose and have never had a problem) "fill the action with CLP or transmission fluid to stop jams" (WTF?) never understood that one....can't even find it in the manual.What am I getting at.....good question....nothing really...C7 has its moments but they are ussually mechanical and thats about it or operator induced.

C7's are garbage. No, I didn't draw that conclusion from a video.

Care to expand on that then??
I have not had or witnessed any issues with the performance of the C7 or C8 FOW, from the Canadian Arctic to Afghanistan. Every issued C7,C7A1,C7A2 or C8HBAR I have used has not failed me,be it in training or combat.
The reoccurring problems have with these weapons is a lack of knowledge of the weapons and their maintenance and poor maintenance of the ancillary equipment (magazines especially).
Despite the fact that those in charge of our arms programs have endeavored to issue the most useless of add on equipment such as
a)Triad rails
b)Elcan Scopes
c)CADEX hand grips on a chunk of rail bolted to the hand guards;and
d)bargain basement collapsible stocks.
The weapon itself is good to go.
 
While I never used the C7/C8 in theatre, I have while I was in the CF. (Non-basic rifles), we've had countless issues with broken handguards, tritium issues, gas tube issues, etc.

I've talked to friends that have used both rifles "in action" and they all agree. Some of the older guys still cry for the C1.

I never really understood what the AR hype was about anyway. There are much more better tools for the job.

You should burn you gun plumbers at the stake, not pee on the system itself.
Its driving a Lada, and then hating all cars...
 
C7 malfunction

IF You clean it once and a while it will shoot,I have only seen that under serious cases of abuse,and only with blanks (some people are not as bright as you would like them to be)

I aggree with this statement.

I've seen so many people have problems because their Blank Firing Adapter (BFA) had come loose. This doesn't allow for enough pressure in the barrel to work the action. Sadly, this is one of the most simple problems but the last people check.

Everyone I've talked to agree that there are better tools for the job, ranging from the firearm itself, to the 5.56mm Nato round.

How embarassing to be doing drill and smack the handguard right off your rifle. (New handguards I might add)

I know it strikes a nerve with many, especially those who buy AR's because they look all tacticool and you can put 500 pounds of tacky accessories on them, but I'm only speaking from my experience.

This is all to say that I don't want one for the tacticoolness:D however again, much better tools for the job.
 
Blanks are the worst thing you can fire through an AR. They're absolutey filthy. Basically, the muzzle gets plugged with a blank firing attachment to build up enough pressure to cycle the action, which fills the rifle up with carbon at an incredable rate. Live rounds won't do this...and they look like militia wogs, so they more than likey have their rifles over lubed worsening the conditions. The BFA allows doesn't plug the barrel solid, it still allow gas through, i should add.

On training exercises we were required to have ours lubed up, but I don't recall anyone having problems like this. Everyone had their BFA's on tight and some even had em tied on with a string incase they fell off.

The ammo wasn't much cleaner though. A typical range outing would require multiple thorough cleanings.
 
:s And here I was asking just what would cause the bullet to go all crooked in the magazine like that... They did prove it was the mag that was the problem, it jammed in two rifles.

So basically, either the lip or the follower, and just drop the mag and go to next one.

And for everyone that contributed to this thread... US army shenanigans http://www.youtube.com/watch?v=gHu_-Xb3_kU&feature=related
