So any validity to this presentation? Is it a big deal? Unimportant? What do you think?
This is why it's important to run the gun very wet and with a buffer spring which is within spec for length. I replace mine when they get to 10 1/4".
i think that video is bs. the people on youtube are always arguing the difference about ak's vs ar's. i own both and nothing jammed like my romanian wasr. different mags, ammo etc. my yugo is flawless, but you can tell my dpms ar is so much better. i'd like to see this guy stick his finger in the bolt of an ak. to many kids on youtube do nothing more than play video games and think they know it all. just my 2 cents
sounds like lube would solve all of this.
I guess Im having a hard time understanding the relevance of what I just watched.
I almost feel stupider :confused:
He is pushing on the BCG at a angle so that the Bcg get cocked in the groove.
Aso a very dry action and no buffer spring. just my 2 c.
Secret to "fix" AR's... 2 parts beach sand, 1 part Oil, work action for 20 minutes.
If problem not yet solved, repeat steps 1-3 :confused:
I must be missing something in the vid...
As soon as he identified the BCG as the "bolt" and the bolt as the "bolt head" my red flags started waving!! :rolleyes:
A waste of a 604 upper.
I see constant references in the description to the HK416...more than likely this is HK propaganda to belittle the AR and push their crap...
This is a technical forum; let's make an effort to keep the discussion technical in nature.
I tried using 2 fingers on the bolt face and the palm of my hand on the on the back of the carrier trying to get it to collapse and bind up no go mine moved just fine no drag that I could find.
that cam pin not in spec or maybe the contact points on the carrier have been ground down allowing the carrier to twist when he collapses the BCG :confused:
I want my 6:57 back... :rolleyes:
I ain't no expert....
I'm pretty sure that it is designed to do that, the gas rings are what gives it a tight fit with the bolt carrier.
One of the op checks that we did was to put the bolt (no cam) into the bolt carrier and hold it vertical, if the bolt fell out, the gas rings needed to be replaced. The next check was to put the complete BCG into the upper receiver (40 degree angle, shotgun stlye), pull the BCG back (not with the charging handle) and let it seat with it's own weight. If the bolt didn't lock then a further inspection of the key and cam pin were required.
I would be willing to bet a large amount of money that he is lifting the receiver up with his other hand. Notice that neither the back end of the receiver or his other hand is in view while he performs this so called test...
I tried the "test" on my carbine just now. My BCG slides like butter with pressure put on the bolt face. If you examine an upper, the cam pin rides inside a channel the whole length of the receiver. The bolt is only allowed to rotate when the cam pin reaches a cutout in the receiver.
He is an HK fanboy trying to stir shit up.
I'd bet a whole dollar that this is the 'einzelherz' I found on that other, other, no not that one site that yapped endlessly about the problems with the AR bolt system and how the PWS system was a fragile POS, but when cornered wouldn't answer questions about his time with the system or his qualifications.
And to boot, here was his list of weapons (and costs):
Quote:
vz24 - 130.00
M91/30 - 90
m38 80, SOME AMMO AND $25
Enfield 2A - 150
Toz 78 - 130
so 1040 for 6 rifles.
3200 is like a lot.
my most expensive firearm is my old steyr M9. $310 shipped.
He has a point IMO, it's basically the buffer spring's job to overcome these forces which compounded could theoretically stop a VERY dry weapon (with no dry film lube in the upper either).
However, the fact of the matter is that how many of the "jams" (must be an industry technical term) you see are simple feedway stoppages that don't include an unextracted\unejected round, or a second live round? It simply doesn't happen often enough to be considered a "design flaw", because other things have to be wrong.
You mean all the COD 4 keyboard commandos?:rolleyes: Yeah I see slot of em at school, they play games like COD4 and think as soon as they see a gun their automatically weapons experts. Kinda funny actually. Like the kinda people you see on yahoo asking how much a "M40A3" costs and you know darn good and well they wouldn't even know what a M40 was if they didn't play a military vid. game.:rolleyes:
He is trying to compare the physics of slow speed "finger" manipulation with that of the high speed physics of actual firing.... Apples and Oranges. When you drive a cars tires across a wet surface at slow speed you have traction (friction), at high speed you hydroplane (loss of friction). His stupid little demo also fails to take into acount the forward momentum and energy of that BCG.
Hence the term "ERRORNET" huh.
In over 26 years of experience with the M16/AR platform I cannot think of a single malfunction that I might have attributed to this.
