What is the big deal about non HBAR being illegal?

Other than weight, what is the real difference in the HBAR sold in stores now? 1 owner of a gun shop told me that the heavy barrel is more accurate and accepts heat better when firing faster. What is the truth? difference?

How about the principle of it? I probably couldn't tell the difference but that's beside the point. No one likes being told what they can or can't do, especially when the criteria is arbitrary, capricious, and stupid. I don't know about you, but telling me I can't have or do something makes me want it all the more.

HBAR question...

I've done some homework and most FFLs/Gun shops have said all HBARs are legal. I'm sill searching for the right one, would prefer 20" in a 1:7 twist but most are 1:9.

My question from minds here smarter than mine on the subject is this - If the manufacturer states it is a "heavy barrel" without actually being marked on the barrel is that legal in MD? Also, if ever questioned about it what would you advise to clarify? (carry with gun - bill of sale, printed material on the model stating "heavy barrel", etc.). Would appreciate your thoughts. Thanks!

Do not forget to include the fact that more mass = lower temp = slower heat transfer ... I think that as exponential in the delta T and may explain a lot

but the it the issue is thermal expansion ( wrt accuracy changes ) temperature not heat would be a very key issue.

And of course barrel harmonics would dominate both i think.

Very interesting -- wonder if any one ever did a formal model to see which variable dominates .. at some T the barrel harmonics may change as well.

Now I am thinking none of this matters at 5.56 type ranges... but who knows.. and I bet trigger dominates the all then wind then cartridge variations and the barrel harmonics

If we ever get to get back to just shooting instead of politics this might be a fun experiment ...

They are all related.

The most important variable is always the nut behind the trigger. I have always found most problems of ultimate accuracy revolve around the trigger nut because most people are incapable of regularly shooting better than their firearms. Of course most shooters don't try for ultimate accuracy, we don't like seeing how bad we are preserved on paper, we prefer minute of gong, kick the can, or knock over the plate.

Now for those attempting the single hole of measurable diameter preserved in paper for all time shooting. Then all the minor variables become anally retentive important and we stop holding our guns and minimize contact with the trigger to achieve nirvana.

IIRC Eley looked at the question of ammunition variables and came up with something like 50 primary variables, 200 secondary variables and 700 tertiary variables in making a single round. When you add all the other variables of gun, weather, shooter it become mind boggling. For some interesting reading on variables:

These guys worry about air density and which machine made the ammo.

And the story of the "Secrets of the Houston Warehouse" has already been covered on MDS, always a great read.

I have an upper with a 16" BHW heavy barrel going on a post 10/1 lower waiting for me in iowa. I printed the description and my receipt from the site I bought the barrel from as the description clearly states "HBAR". Just keeping that in a safe place.

Well, clearly the HBAR has a heavier barrel, so it's for target shooting sportsmen. The non-HBAR ARs have the lighter profile barrels pyscos prefer so they can run and jump over and roll with a lighter rifle when they go to shoot up a bus full of nuns taking orphans to adopt mistreated shelter puppies. When was the last time a killer used an HBAR? Let's not assume our dear leaders are ignorant, they know stuffs.

Actually the Beltway Sniper used an HBAR Bushmaster... of course he could have accomplished his goal with a bolt action .22 or a butcher knife.

You can't stop crazy...

No... The killers did not use the HBARs... Ask anyone in the MSM or any libtard... They will tell you that the killers were used by the guns. Those guns are EVIL.

















Really? If you did not know that was sarcasm... Then you really need to read the New York Times for your health.

That Bushmaster was a totally different gun. But the MSP is taking the bonehead interpretation of including the Bushmaster AR.

How come nobody mentioned that the HBAR does not have the cut away where one can mount an M203 launcher? THAT'S why they want it banned. So we can not launch our greenades.

Not like that matters. The launchers that Spikes Tactical sells don't even use that.
