Something I find really interesting and engaging about Karl’s delivery is his pace. Some presenters are really rushed and high energy, some are really sloooooow and laid back. Karl has the speed of the rush, but in a really consistent tone that gets the viewer all the way through the material at a good pace without feeling rushed, dragged out, or kurt. It’s a very unique style on youtube and I find it fits very well to the content.

Yep, regardless of subject matter certain presentation styles work better than others, personally i find the high energy rapid cut style to be annoying and sometimes hard to follow (a bit like a Michael Bey movie lol), i also enjoy it when the creators personality comes through and you can tell when someone is faking things. Big thumbs up to Karl for style, professionalism and personality.

The thermal camera footage is very well done, and helps to clearly illustrate the points being made. And i agree, Karl's delivery is always excellent, clear and concise. Keep up the great work!

2:36 main reason they switched the charging handle to the rear was mainly from the artic testing grounds. Due to wearing big gloves in cold conditions, the guys testing out the AR rifles found it difficult to get at the charging handle. Hence, why you find the charging handle on the back of the upper receiver on AR rifles today and not on top of the upper anymore. This can be found in the Eugene Stoner interviews here on YT and he explains exactly that.

This was something I'd been told about the two systems, but seeing it happen is always better. Thanks!

This is cool, just having this stuff explained doesnt allways help but actually seeing it leaves an impression

Cool Footage! I'm guessing the middle of the Scar Upper is heating up because it's where the barrel bolts to the receiver and the 6-o'clock rail.

That SCAR looked like it was getting REALLY hot in the block and barrel compared to the Brownells. I would love to see a burnout video like the do over at Iraqveteran8888. The effects of high round counts in a short time. Because let's be honest here. The AR15 if properly lubed, not doing that glove dry myth, will function just fine with 800rnds worth of blowback across the bolt. Cleaning happens between engagements whether its an AR or an AK.

Amazing stuff!

Thanks for the interesting video, it’s always neat so see the information visually. I’m seeing noticeable difference in fouling between my AR-15 and BRN-180S. The piston gun’s bolt and carrier are cleaner at 500 rounds than the semi-DI‘s at 50.

@onelonecelt9168

4 жыл бұрын

Piston guns also keep the bolts and carriers cooler during use, theoretically increasing service life of the action components. On a side note: does the handguard on the BRN-180S heat up noticeably during fire? I am interested in them, but I am leery of the m lok handguard they have on it.

As a left-hander, I prefer pistons over DI because the gas is bled off further from my face. This might not seem like such a problem for most but unless you're able to shoot in a dynamic environment like 2GAC, a gas cloud builds up in your face even in outdoor ranges.

saw a great video to illustrate this point years ago with some piston ar15 style rifle, dumped 3 mags on full auto, dropped the last mag and immediately opened it up and pulled the bcg out and held it with bare hands (no video cuts, was holding the bolt less than 8 seconds after the last shot fired), then challenged the video host (i think it was an old tv show) to do the same with his DI gun

Nice! Thanks Karl. Rich

id like to see more thermals on more guns like the fal, g3 or an Aug.

awesome dude.

That was fun , I like my FN scar 16 & 17 , that said ..my friends AR 15 & 10 run just as reliability at a fraction of the cost .

Very informative

Very interesting video. It seems like the heat is "spread out" more in the DI gun. Like no one spot gets as hot as the piston area in the short stroke gun. I would have been interesting to see what the temps were in the hottest areas of both guns. Keep up the good work in range.

It’s interesting to think about the triad offs of these two systems along with others, whether it be reliably over extended firing or accuracy over longer durations or fire. I,as a viewer would love to see a comparison of the accuracy over sustained fire and as a result of that test see the reliability of these two systems.

Another point of note is the balance between the two systems. It’s not as pronounced with a rifle designed from the start to be a piston gun but on ‘converted’ ARs like the T91 the change in balance towards the front is majorly noticeable and it takes me a while to compensate when going from a 14.5 AR to my T91 clone.

Do more action types please. Different handguard materials and designs. Heat molestation is really a thing when you shoot a lot. This could get interesting

Very interesting.

Extremely interesting

Can you do the Ar 180 upper? ( thermal image it)

Neat! Are you planning on showing us the rest of the guns? Could make a cool cyberpunk kinda vid out of the footage if you don't see much educational value in it

Brilliant.

Interesting. I would really like to see the bolt face next time around. Too see how much heat transfers to the bolt in both systems.

Every time I see one of these videos I wonder if this is Karl's back yard. And if so...simply beautiful.

@coreyp9211

No. Even though there is more heat being distributed to the bolt carrier in an AR, the parts don’t get anywhere near hot enough to damage anything or cause any functional disadvantage. In fact the actual advantages of the AR’s gas system (less parts, lighter weight, smoother recoil impulse) far outweigh any perceived advantages of a short-stroke piston system.

So basically, barrels get hot on piston systems. Barrels, bolt carrier's, and gas tubes get hot on an AR (whatever you want to call that gas system). So both of them get hot in the area where you hold them, but the AR has a second hot thing that runs the full length of the handguards and is closer to the hand than the barrel.

I was wondering if IRTV was going to do a video about this topic, ever since I read a gun forum posting saying a DI system doesn't heat up the barrel like a piston system does. :-)

I do wonder if the less bolt heat advantage is why the M27 IAR got accepted as the USMC SAW instead of other entries. Alternatively, one of the other entries, SCAR HAMR, also operate on a short stroke piston, perhaps there was a flaw in the SCAR design that didn't made it favorable compared to HK's bid?

Could you please film a series of thermal videos with different types of AK/handguard setups? I have owned a few AKs and one recurring problem seems to be just how hot they get from shooting. A lot of the handguards that I used have not been up to the task of keeping all that heat away from my hands.

Interesting video. Are you sitting out in the desert southwest someplace? Looks like west Texas

A question that struck me as I watched the final comparison is if either system cools down faster or if that's just a mater of the materials ability to radiate heat. You'd think more surface area would allow better cooling but theory isn't always practical.

Id like to see how a roller locked/delayed system compares

Do you got the spec on the thermal camera used here? Can't really tell much but it must be VGA or greater resolution. As reflectivity is an issue, it might even be a cooler MWIR system? There seems to be fixed pattern noise tho, which is more of a microbolometer thing.
