laws and AR build

[Biggfoot44]

Even if we ignore NFA and FSA 13, heck even if we do a pistol build, there is big issue with a 1.0 inch bbl.

Nasty fragments when firing a 2.25-ish ctg from it.

No. Copycat test. Unless you have a really long stock to make 29" OAL.

I was thinking just throwing a big ass piece of aluminum for a stock.

I thought that's what brass deflectors were for

alright thanks, any suggestions for a mil-spec 20" a2 style HBAR with a flat top? preferably with a removable carry handle

Get a fluted 16" HBAR flat-top upper from Engage Armament. Your arms will thank you.

Now I'm confused. Is this Md legal?

That'll work!

Yes it's advertised by the manufacturer as heavy therefore it's legal.

Yep.

Or a really long permenatly attached muzzle device

A 15" perm-attached muzzle device lol (to get around NFA)

LOL, someone do an illustration.

Theoretically, sure.

TacSol actually sells a .300BLK upper that's like an 8.5" barrel with an 8" permanently attached shroud on it. You slip a suppressor inside the shroud and it threads to the barrel. No NFA anything on the rifle itself since technically the barrel + permanent muzzle device is over 16".

Filed accordingly.

Well, the Colt I mentioned had that barrel profile where it tapered to .750'' a short distance in front of the chamber under the handguard. I had asked about the barrel profile so we took the handguards off and looked. I should have bought it.

So I understand that some are saying that a barrel marked HBAR or commercially sold as HBAR is legal. Is there anything from stopping a barrel maker from turning a barrel to 0.002" over government spec in tactically relevant positions on the barrel and slapping the stamp HBAR on the barrel?

Nope.

Unfortunately, since "HBAR" isn't defined anywhere in the law, there is also nothing to prevent MSP from coming up with some other arbitrary and capricious way of defining it, either.

 

[noahhh]

I recently built a MD-compliant rifle with 20" H-Bar. It came in at a tad over 8 pounds. Then I added a Vortex Crossfire II scope 1-4 w/V-brite reticle (which I'm loving) and the weight is now 9+ pounds. Holy mackerel! It's good that all I ever plan to do with it is shoot it off the bench now and then, so in the end I'm not too upset. (Especially since it is a well under MOA gun the way it sits.) If I build another one it'll be with a 16 or 18" fluted heavy barrel.

So this is legal in MD, but heavy as a cow

Technically the very first experimental AR's had a .5" profile barrel (IIRC). They experienced barrel bursting issues and drooping issues after FA fire. Sheer technicality the Gov't profile is an HBAR. Also in the stupid AR HBAR category a Colt 6920 SOCOM carbine is MD legal but a BCM SOCOM carbine isn't because Colt advertises the 6920 SOCOM as an HBAR whereas BCM doesn't.

A 20 inch HBAR will weigh 3 tons. 3 tons and 4 ounces if you put 45 degree sights on it.

A 16 inch would be a better choice. Still heavy, but usable.

I was just going to chime in with the same advice. My heavy middy is very heavy. 20 inch heavy? Boat anchor heavy.

 

[Magnumite]

Weight isn't the worst part with a 20" HBAR. The balance is rough with a light stock. I tried a collapsible stock with a 20" HBAR upper and had to put lead shot in the battery storage cavities to get decent balance.

To the best of my knowledge, 5.56 x 45, .223, .223 Wylde.

so if you built a .22lr upper you counld have any barrel profile you wanted?

As long it is a dedicated .22 I believe. IANAL
