I'm thinking of going from Hbar to govt profile.

My Hbar is starting to grow a little old on me and I am getting evil thoughts about sending it off to fat camp. But first I would like to know how much of a difference it would make. Anybody know how much lighter a govt profile midlength upper is compared to a Hbar?
 
It is a highly noticeable diff, you will like the govt. profile, and if you got real guts, go old school and get a pencil bbl...
 
if its a colt id hold on to that barrel and all of the parts. colts can bring pretty good money used if original and in good shape. Putting an aftermarket barrel on it is going to toss that out the window if you dont keep your parts.
 
I'm going to get the SP1 configuration. Can't wait ;) I just can't see any advantage the gov't profile has over the pencil ;)
 
Well, if in combat mode, the pencil bbl will heat up faster, and really gives good whip effect , once hot, the govt. profile bbl is deff stiffer when hot.
 
What's the actual difference in diameter between pencil, gov't profile, and hbar - anyone know?

Note that the barrel can have at least 3 different diameters along its length.
 
In the same vein, which is cheaper:

swapping barrels in and out of an upper,

or sending an upper to Adco for barrel reprofiling?
 
I built one of each: 20' HB A2 and a 16" lightweight carbine A2. After shooting both and seeing no real difference in accuracy, I gave the HB 20" rifle to my dad and kept the carbine for my own use.
 
Thanks.
Anybody know how much ADCO charges extra to remove the barrel from the upper? I can't seem to find it on their site. It would cost me at least 60 dollars for the wrench and action block to do it myself.

The barrel is a 16" Delton midlength.

I also thought about buying a CMMG pencil barrel but they are pricey and with the way things are going it would probably be this time next decade before it got delivered.

Funny, you and I are in the exact same boat.

I think I recall Adco will do the job for $150ish including barrel removal and reassembly.
 
if i can i will always do it my self not because of the money but for the experience and self rewarding.
 
maybe you guys can split the cost of the equipment. then after, one gets the wrench and the other gets the block. Then if you have to do it again, you will only need to buy one part.

This way you guys get your experience, a new tool a piece, and new barrels.:)
 
If I were doing it, I would get a whole new upper and configure it differently. That way you would have the advantage of having two totally different rifles by simply swapping uppers.
You could have one flattop and one A2 or one 20" and one carbine, or one with a 1/12 twist and one with a 1/7 or 1/9 twist etc.
I did notice my .22 conversion is more accurate in a slower twist upper.

Later, if you decided you didn't want one, there might be a bigger market for a complete upper than just a barrel.
Just a thought. . . . . . .
 
The problem with getting a new upper; I like everything about it but the weight.

CMMG has a stripped lightweight barrel (MP tested, Chrome lined) for $255, but that leaves us with a heavy barrel that might be tough to sell.

Perhaps we SHOULD strip our uppers ourselves and send the barrels off to Adco...

If I do that, I'm going to totally reconfigure the upper anyway...

So maybe we should build new uppers...

Whats the resale market look like for bone stock 16" midlength uppers?...

:)
 
Well I went ahead and bought a wrench/ combo tool at a gunshop. In order to make things easier on my small gun budget I will spread everything out. A couple paychecks from now I'll buy the action block and next month I will send the barrel off. It will also give me some time to think of some other things I might like to do with it while it is taken apart like a free float tube and maybe a another flash hider.

It never hurts to have a spare barrel lying around.:)
 
You guys talk about getting a new upper like it's easy these days. I've tried and still can't get one. I had to buy a whole rifle from a dealer at inflated prices.
 
Under the handguards, an H-Bar barrel can run 1.25" down to .750", most average about .890" and step down to .750" from the front sight tower to the muzzle, some step down to .712" or .725" at the muzzle depending on the manufacturer.
A Government profile barrel runs somewhere around .687" under the handguards and steps up to .750" from the front sight tower to the muzzle.
A 'pencil' type A1 barrel steps to .687 under the handguards, steps up to about .715" at the front sight tower and steps back down to .687" from the tower to the muzzle.

Going from a standard 20" .890" diameter H-Bar to an 18" midlength government profile barrel will knock about one and a half pounds off the weight of the rifle.HTH
