Hey all. Been a lurker/heavy reader for a year, finally decided to post my first question.
I have a DPMS stainless 1:8 20" Hbar on my rifle that I hope to someday use in 3-gun, but I am tempted to have ADCO or the gentleman from www.ar15barrels.com turn it down to .650 under the handguards, similar to Govt. profile. I love shooting it, but she's a real porker. Wonderin' if anyone the best way to lighten this thing up? My ideas are to have it shortened to 18" and made .650 under the hanguards, or .750~.800 under the handguards if .650 is too thin. I'm looking for something like a Govt. profile barrel, but in 18".

I spent some time on www.JPrifles.com, and they have stainless 18" barrells in the lightweight (.650 under the handguards) profile... but someone on AR15.com posted you may get accuracy deterioration when turning a stainless. Is this true? Should I stick to .800 under the hanguards instead?
I drew up some specs for my new profile in Illustrator based on my 20" HBar I have now. The front diameter past the .750 gas block area is already .720, so I thought about leaving that the same, but lopping off 2.00" and rethreading for my comp.
Does this profile look favorable for 3-gun?
