[ARCHIVED THREAD] - Looking for options to have a heavy barrel reprofiled

Posted: 2/13/2006 7:10:05 PM EDT

Looking for any and all shops that can dissassemble an upper and turn a heavy barrel to government profile. So far I know of Adco, anybody else?

Thanks in advance

I've had work done by all 3 and can recommend their work.

Does the FSB have to removed from the barrel for this? I have a permanently attached FH.

Same question, but for fluting?

Yes for profiling... it has to go in a lathe and spin.

I don't know about fluting, but I have both and prefer profiling for cost and weight savings. I've never seen any advantage in the two fluted barrels I've owned over the three profiled ones.

Any of the guys mentioned can also remove your permanently installed flash suppressor for a little extra $ (maybe $20 or $30) and then install a NEW one after they're finished.

For that effort though, it might be cheaper to replace your barrel with the profile you want and sell the old one.

I kind of have the same question. I have a post ban Bushmater A3 20" HBAR that is just too damn heavy. If I have the barrel threaded and reprofiled, whill I notice any difference in accuracy at 1-300yds?
What has to be done to thread it to govt. style. There is a smaller profile at the end of the barrel, is this what gets threaded?

Unfortunately MRP barrels only come in one profile. ;)

Well now you didn't mention that the first time

They actuall DO come in more than one profile, but only in different barrel lengths... The 16" is .750 I believe and the 18" is more like SPR profile (.840-ish).

I know this because Zak-Smith told us so

If your barrel is a mid-length, and your barrel profile is medium (.750-ish) then you'd probably only shave off 4 ounces by going with A2 profile... It would be noticeable, but would it be worth the expense? Only you can answer that.

To thread it the muzzle will be turned down and threads cut to 1/2"-28 pitch. I don't know about the gas block diameter section and end of barrel on a Bushmaster, but if it's HBAR the section under the handguards will be turned down on a lathe to a smaller diameter. This is where most of your weight is.

For me I want to have this done on a RRA mid-length barrel, it's pretty dang thick under the handguards. Right now it looks like the job would cost me $100-150 for dissassembly, machining, and refinishing.

It will be be over a half of pound of weight savings, but less than a full pound. If I were to guess I'd say around 0.7lbs of steel would be removed. You will notice it.

I have profiled around a FSB with it still in place.
It's scary and I don;t like doing it, but it can be done.
Typically, I can knock the pins out and slide it forward and just let it spin near the muzzle while working behind it.
There's no easy way to work out in front, but most lightening jobs are just under the handguards, but it's not nearly as scary when the tool is on the other side of the FSB.

For fluting, the permanent muzzle device AND FSB would have to come off for sure.

Thanks, I just got a 16" barrel instead so now I have "options."
