Canadian Infantry firefight video showing many malfunctions of the C7

HaHa, looks like Dirt MGirt struck again and totally baffled those who have not been exposed to him!!!!:cool:

Yeah I thought everyone on GCN was hip to the Dirt. I guess he doesn't darken the doorstep of the Black and Green Rifle section much. I figure he is kind of like The Stig of CGN...perhaps someday we will learn his true identity.
 
Hard to tell with time lapsed video, but I'd wager a guess he had stoppages with more than one particular mag which would lead me to believe he has some lube issues.

Yea the only way monopoding your rifle on your mag causes issues, is if it's an out of spec mag or gun, if everything's to spec, then you're really g2g.... when i shoot my AR prone, I use the mag as a monopod all the time, never had any issues, though I DO use PMAGs

unforchently the mono pod stopage is caused by out of spec mags; often caused by mono poding ... those alluminuim mags deoform easy, and the mag locking hole gets streched out from either people wacking the mag or monopoding... eventualy the hole is streched too far and the mag can be pushed in far enough to interfer with with the weapons operation. That same mag can still be shot fine untill it gets pushed up from the bottom... so the "myth" about monopodding causing stopages has more truth to it then many of you think. I have had more then my fair share of mags like this; and because they still work when you "use the gun properly" its hard to find a CQ that will exchange them.
Overseas I found if you didn't take the mags apart every two weeks and strech out the springs and straighten the lips, they wouldn't even feed rounds.

Sounds like you might have been the cause of your own problems. Stretching mag springs is precisely the wrong thing to do. Mag Springs can be left compressed or extended almost indefinitely with no ill effects. It's repeated compression and extension cycles (ie; use) that wears them out. Stretching them only exacerbates this problem, and drastically reduces the springs life. A normal quality mag spring will go through many thousand cycles of compression an release with no problems. Stretching them, will reduce their useful life to less then a tenth of that.

I think it's a bit of an exaggeration to say that aluminum mags deform easily. I've used all sorts of mags and have never encountered one that caused stoppages because the mag catch hole was out of spec. Anything is possible, but it certainly isn't a regular occurance.

Guys "stretching the springs" is a contributer to unreliable mags. If the mag is so worn out that it doesn't feed rounds exchange it with the CQ. If not, there are always free USGI mags, 100 to a box...not hard to get or $12 PMags at the PX. For $120 you can eliminate mag related stoppages on your basic load. Seems like a worthwhile investment.

Resting the rifle on the magazine does not cause stoppages.

pffft. What do you know. It's not like you've ever served overseas or been in a firefight and put rounds into the enemy... oh.. wait....

That usually means the mag should be replaced... They are considered 'consumables'. What did you use to measure the the spring length before stretching them out, and how did you 'straighten' the lips? Did you get a gauge from the armorers to conduct battelfield maintenance?

Big_Red beat me to it...
 
I'm pretty sure that guy had more stopages in that video than I have had shooting the platform since 1988.

Something seriously wrong there. My guess would be mags.

Amen to that. Not as long shooting, but same here.

I'll thirds the don't stretch the spring, its not supposed to extend past its natural point.





So boys what the f**k is causing the mag lips to separate? I honest to god am stumped.

If youre going to "myth bust", ya cant leave me hanging like this!:p

The spot welds on the front and back of the mag can break. If you can squeeze the lips in and see motion between the two halves it needs to be destroyed. They look fine but when loaded they will bulge, sometimes to the point of not fitting in a reciever.

Anyone who turns in crap mags because it is easier then getting them written off is screwing his fellow soldiers.

Well since the spring was little longer then the leangth of the mag when I pulled it out i streched it to doulbe the leangth and put it back in... problem solved for another week... as for the lips, I would get it as close to an unused mag as possible then test to make sure it fed properly... I only did this on mags that had feed issues were either the rounds were practicly falling out of the mag causing double feeds because the lips were too lose; or when the bolt running forward could not peel the next round out (happens if they get dropped on the lips)
its all nice having P mags for sale at the PX, or the theory that I can exchange them with the CQ (so I give you 5 ####ty mags and you give me 5 ####ty ones back... awesome) but neither helped me when I was in a strong point were we saw a KAF supply run 1 once a month (so 2 month turn around) and a food run to the local NSE node every two weeks.

those alluminuim mags were the bane of my exsistance, you could warp them simply by dropping them loaded on cement if a corner of the mag hit first.
 
Mag spring retention

His issue is Magazine spring retention in the sandbox your suppose to unload your mags every week to relieve tension on the spring inside them if you do not this leads to lots of weapon malfunctions of misfeeding rounds as they are not picked up by the bolt as there is no tension on the spring.
Just my two cents worth as Ive seen it happen in the firefight before

That's a myth.
 
*Speaking solely from personal experience* the only time I had a string of stoppages anywhere near that bad with a C7 was on the range. Settled in for my initial grouping and zeroing string and could only get one or two rounds off without a stoppage. The AF staff was a little freaked cause I cleared the weapon, stepped off the line and started stripping it on the spot. Turns out the bolt was crudded up with dirty oil (Airforce shoot, so not my regular issued weapon) quick wipe down and function test and I was back on the line issue free.

That kind of shenanigan only happens in the simulator and in a battleschool classroom.

I was specifically instructed to place the mag on the ground for stability when firing prone. I would say that the mag had an issue. I always found the C-7 to be reliable when kept clean and fed from good mags.

Yes and no! A properly tempered spring with the right quality steel will indeed last a very long time ( measured in years ) because they are compressed within their elastic limit. However, cheaply made springs can indeed lose strength even though within their 'elastic" limit. It does not happen often but I've seen it on a couple of Korean AR mags from the 80's. Poor spring steel or poor tempering.
 
A bad mag or sand in the mag. I had some what same problems when I was on a Rifle's only course, BCR EX ,1 MPU range EX. No problem with that C7A2 or shooter (maybe dump that mag and get a new one?).

Glad to hear it. I was told all sorts of retardation on basic courses. Good thing I already had an AR of my own at home at the time so I was wise to their shenanigans.
