I am looking to purchase my first AR-15. I have narrowed it down to a Bushmaster 20" A3. The final decision is to get a Government profile or HBAR. I know it comes down to personnel preference but does anybody know the actual weight difference between the two rifles. Also debating 1/7 or 1/9 twist but that is another story.

It will be used for range work and an occasional 3-gun match at distances less than 300 yards.

Thanks

So there's a 1 pound difference between 20" Gov.profile and 20" HBAR.

My HBAR A2 BM Upper is for sale in the EE because it's too front heavy for my liking.

Good riddance!

One pound does not seem like it would make that much difference. Thanks for the information.

Carry one around all day, you will notice it

To add my two cents worth,

I have had a post ban RRA - with a J&T 20 Hbar kit - heavy and added a baggie full of screws to teh butstock for more weight - I shoot service rifle matches with this gun.

I have just put together a RRA lower w/ a adjustable butstock and a M16 upper w/ the older triangle handguards.

These two guns are like night and day - I will say that the gun with the old style pencil upper kicks harder than the heavy barrel.

not much and I am not complaining - just noteing the difference.

YMMV,

HAH! It's a huge difference. Remember, that's cantilevered weight that you are holding out in front of you


Take a 3 day carbine course and you'll know which one you want

I have no doubt if I were carrying an AR around all day I would want the lighter weapon but I am a desk jockey that only shoots at the range and a few 3-gun matches and service rifle matches.

Is the lighter recoil in the HBAR enough of a benifit in action shooting to justify the weight?

Thanks

A 20" Gubment profile feels as light and fast as a 16" barrel after you screw around with a 20" HBAR for any amount of time.

In true ARFcom fashion, I have both. If I plan on doing anything more active than sitting at a bench, the M16A2 uppered rifle gets the nod. I'm even thinking of getting my HBAR turned down under the HG's because of the weight. A Government profile 20" A2 (or A3 in your case) balances PERFECTLY, IMO.

I have plans for another one or two 20" Gubment profile rifles because they just feel right and they shoot really well.

BTW, you aren't going to notice too much of a difference in recoil. Since it still has the rifle gas system, it will still be pretty gentle. The lighter rifle (gubment profiled one) will pop a little harder into your shoulder, but it's nothing a 10 year old coudn't handle.

Not to me. I've changed all my rifles over to lighter profiles

Thanks Wizzo... Looks like the government is the winner. Any suggests on twist rate would lso be welcome. Bushmaster has both 1/7 and 1/9. For my uses I think 1/9 would be a good choice but again I am just learning.

I've seen the light, no pun intended, and discovered the beauty of lightweight barrels. Even the balance of the M4 Govt profile seems a little nose heavy and off balance to me now.

Odds are I will only buy lightweight barrels in the future. I would only beef up the barrel if I was building a precision weapon
