Not sure those tests mean anything, but it was cool to watch.

Super Dooooody went to 901 and the gas tube went, not the barrel.

Would be cool if the barrel profile was accounted for in there, somehow.

Colt has entered the chat
M4 vs. M4a1 carbine; destructive testing


At some point physics comes into play. If you run something beyond spec, you can expect failure at some point.  Engineering is always about trade offs.

M&P Sport II test

Smith and Wesson barrel outperforms both.

I wouldn’t expect my Noveske stainless lightweight barrel to hold up as long as a chrome lined hammer forges bull barrel, nor do I need it to.

Damn killed in under 600rds.

Probably psyop.

If anyone in the area wants to volunteer a full auto lower, I'll repeat the test.

I've done 1500 in one sitting but semi/bump fire

Probably the most rounds that have ever been shot through an SR-15 in a single session and in it’s life.

I have a dedicated PSA stainless mag dump upper that did better.

Melted the gas rings after 3 1k sessions. Only casualty was the gas rings.

I have photo, video and two people on this site who witnessed it

Now do a PSA rifle and then a SOCOM barreled COLT.

I only shit on KAC mainly because of the artificial shortage and inflated prices. Decent buy at the old prices, which are long gone.

I am surprised that it blew the barrel out rather than the gas-tube.  Do they use some sort of inconel toob?  I suppose the DD blew out the same way though.

I didn't even watch the videos because I was a man when ammunition was cheap. Furthermore I'm a suburbanfag so when I get access to land I GO FUCKING HARD.

The last trip, between me, beitodesstrafe and BigMan74 we sent over 10k rounds downrange in 6-7 hours

100% of my training involves bunpfiring at dirt clods and piles of garbage.

If someone offered a carbine class that focused on those fundamentals I’d be the first in line.

One of my favorite things about Bill Geissele and Trey Knight is I've heard both say they grew up shooting at trash

The Instagram/FB wants you to think it's not normal to just dump rounds at trash.

It is normal, it's fun, and every guy who is cool has done it. It's it cool to become better? Of course it is. Is it cool to improve your gear? Of course.

But you're a giant faggot if you don't like turning money into noise. It is THE American pastime. Cars, guns, rockets, whatever. We turn money into noise here

I can't stand channels like that. He talks crap about Daniel defense on how they are unsafe because he uses them improperly to destruction when barrel profiles and the ar15 platform was not designed for this kind of sustained fire. There is really no value in these videos as it proves nothing.
