2 inch barrel on AR-15 SBR

Primer

Totally ridiculous! What an idiot and "What Ballistics"!
Because the 223/5.56 Round is already over 2.260" in Total Length!

So the Bullet is almost literally sticking out the end of the Barrell!

I would have to think that those bullets start tumbling the second they’re fired, and they probably don’t make it more than a dozen or so yards. What I’m really shocked about is that the thing cycles- I can’t imagine there being enough gas pressure to do so.

 

I'd be willing to bet that he couldn't hit a 12" steel gong at 25 yards with that thing.
That barrel is only a case chamber, no rifling to stabilize the bullet at all.

 

Why? Because you can.

Doesn't mean that you should, but you can.

 

For every pot, there's a lid.

 

If somebody hasn't done something stupid, somebody will eventually do it.

 

Not in my house. Half of them are MIA, but we have plenty of aluminum foil.

 

And more accurate

 

cuz they could.... Chitz n Giggles I suppose.

 

Bull
I am with you! He had to improvise somethin on the Gas Block. I also can not understand how it is cycling! Because obviously it is a Gas Impingement system.
It has me baffled!

He obviously figured out some way to do it- I just can’t figure it out

 

If he is monetized this video will eventually bring in $$$.
At the moment though not many subs or views.

 

Primer
I have reviewed the Video again and again. And I think you have something there! I would say he has made a special Lighter Buffer, Modified the Spring and may have modified the Bolt? I also noticed an off set in the Low Profile Gas Block on the Rifle. If the Spring, Buffer were modified all the Gas would have to do was unlock the Bolt Lugs from the Barrel Extension Locking Lugs when the round went off. And with a modified system it could almost act like a blow back system at that point to cycle.
The reason I think your onto something, is by closely viewing the location of the Ejection Pattern when the Casings are Ejected.
Here is a chart to confirm he has obviously modified the Gas System. You will notice compared to the Chart that the Casings are almost flying back at 5:00 O'clock in the Yellow Section of the Chart. That is not normal at all for the AR-15. IMO he had to modify the system because if he had not the Rifle would not function. With every part being noral it would be short stroking and not running like it is.

So other than it being a stupid Idea and totally impractical. To each his own!

Impractical to say the least. Hell- I can’t imagine there even being enough barrel to get any rifling in that thing

 

For me, it ranks right up there with putting a small block Chevy V8, backed by a compact power glide, into a motorcycle frame. No practical use, more of a just because you can thing.

And yes, for the last 25 years, there has been a company making bikes like that. Also with big blocks, and current jokes with LS engines. Another one uses a turbine engine from a helicopter as well.

If a person can dream it up, someone will make one, and someone else will buy one.
