    Whats the difference between an HBAR AR15 and a regular AR15?
  2. Dr. Dickie

    The HBAR stands for heavy barrel. Military rifles have a lighten, thin barrel beneath the handguards, where the HBAR is a thicker in that area. Heavier barrel is supposed to make it more accurate.
    That is my understanding, if I am wrong then please let me know.

    That's exactly right Dr. Dickie. Well except that an HBAR doesn't automatically mean it's accurate. It just means the barrel is stiffer than a thinner barrel of the same length. That is normally a good thing for accuracy, but there are lots of other variables in how that barrel is made.

    Unfortunately Loxety, "regular AR15s" do all have HBARs these days. To get a lightweight barrel, you have to pretty much specially order it that way. Some M4 type carbines (which are supposed to have a lighter, thinner barrel under the handguards, see pic below) are HBARs with just a cut in front of the sight to make them only casually look like M4 profiles, very misleading.

    Always ask the seller to remove the handguards so you may inspect the barrel thickness between the reciever and the front sight block.

    Some common barrel profiles:

    A1 profile: 20" Thin all the way (sometimes called a Pencil Barrel)

    Superlight: Pic Here. A 16" barrel same as above.

    A2 Government profile: Pic Here.Thin under the handguards, thicker in front of the sight. Usually 20", some 16" Midlengths are made this way.

    M4: Pic Here. 16" Thin under the handguard, thicker in front of the sight, but has a groove cut there (to mount the front of the M203 grenade launcher on the military guns). this profile is sometimes seen on Bushmaster Dissipator barrels.

    M4 SOCOM: 16" Heavier under the handguards, but has a groove under there aslo, to mount the rear of the M203.

    Then there's the HBAR. Pic of a 16", pic of a 20"

    The HBAR is a gimmick that many manufacturers use to cut down on machining...

    It's not very beneficial in a tactical rifle... I don't even like them in a "sniper" or even a "hunting" rifle.

    The AR is an inherently accurate design and a lighter barrel makes it easier to carry.

    The only time a HBAR does anything is if you shoot it a lot on full auto (which isn't an issue for most civvies), and even then, it wasn't meant to be a machine gun...

    Govt profile (or superlight) all the way! ;)

    It should be noted that many people refer to an M4 (light under the handguards) profile as a govt profile as well.

    I also think it is mostly gimmick to reduce lathe time BUT...

    I like to shoot my rifle while HOT, and I don't notice my groups open up as much as I think they would if I had a thinner barrel profile:) .

    A salesman at a local shop said that HBARs are not a regulated firearm in Maryland. A normal AR15 is and requires the states 7 day wait/background check.. where the HBAR can be taken home the day you pay for it (like a shotgun).

    Gun laws are all the same... There is no logical explaination for the reasoning behind them...

    And that means that HBARs sell like hotcakes at MD gun shows; nonsensical laws allow it, but who's complaining?

    Dealers simply put out a placard reading "Take it home today! If it has HBAR written anywhere on the gun, it's non-regulated" and rake in the cash.

    Believe it or not, some guys prefer the H-bar for its handling characteristics. Try to find some thin barrels on the Camp Perry line. ;)

    I wouldn't want to drag one around all day, but I do like having a heavier gun when shooting highpower.

    Then and now.

    Then, I carried an M-16 around and would have complained loudly at any more weight.

    Now, I have a 22" HBAR that I pop 'yotes and groundhogs with and like the extra weight out front.

    Go figure.

    Are they both mechanically the same with the exception being the heavier barrel? :banghead:

    I bought a 16" HBAR, mainly because it was the only 16" they had in stock. So far I like it, the extra weight doesnt bother me. As for accuracy, if its any different, its not enough to be noticeable.

    My HBAR. As others have pointed out, there is no difference in barrel diameter. Same all the way down:

    All I'm saying is I have owned HBAR's and saw very little benefit in practical accuracy and I often shoot coyotes with my govt profile barreled AR's w/o a problem.

    Do HBARs have tighter chambers than a standard AR-15? Will HBARs handle crap ammo like Wolf?
  17. DMK

    DMK Well-Known Member

    Yea, but these are the guys putting lead weights in their buttstocks and in their handguards. That's a special situation with special needs. Absolute accuracy overrides everything within the set rules.

    Personally, I like my AR light like a carbine is supposed to be. Weighting it down is like weighting down an M1 carbine and defeats the purpose of the rifle IMO.

    Silly legislators. So then you can take it home and swap on the lightweight upper you bought earlier. :rolleyes:
  18. RockyMtnTactical

    The chamber will not be any different in an HBAR. When you're talking HBAR's versus govt profile/superlights all you are talking about is the diameter and thickness of the outside of the barrel, it has nothing to do with chambers/bores....

    As for the Wolf, all of my guns handle wolf fine. I've found that guns of lesser quality have more troubles with steel cased ammo, in general.

    You can get chambers sized for 5.56 (military spec), .223, or Wylde (in between 5.56 and .223) regardless of external barrel profile.

    If you plan on shooting Wolf, you might want to get a 5.56 chamber and chrome lining. Definitely do so if you plan to shoot surplus ammo.

    Exactly right. I bought my Hbar with the specific purpose of service rifle competition. I have a large ziplock bag full of lead shot in the buttstock adjusted to make the rifle balance perfectly for me. Lead weigth or not, I wouldn't want to carry it around all day- its heavy.
