beachmaster Posted January 16, 2014 Report Posted January 16, 2014 Hi, I have a black rain ordnance 18" barrel, and I couldn't get any information on it. I got ahold of b.r.o., and they informed me that the barrel weights 3.9lbs! (I knew it was a little heavier than I thought it should have been!) I believe the section of barrel behind the gas block is over an inch in diameter, so I talked to my local gunsmith about the possibility of turning the barrel down to maybe .8" I have heard alot of people talking about doing this, one person with a barrel lighter than mine from the factory took 13oz off his barrel. But I was looking for oppinions on the effect on the accuracy and longevity of a barrel if you have this done. Thanks in advance for any input!
FaRKle! Posted January 16, 2014 Report Posted January 16, 2014 Re-profiling the barrel shouldn't affect accuracy much, but the barrel will heat up more quickly which may lead to vertical stringing. You shouldn't see a difference in barrel longevity (wear).
beachmaster Posted January 16, 2014 Author Report Posted January 16, 2014 thats what I was figuring. If I were to do a 3 gun I would expect some stringing, but for a normal day at the range or hunting I figured I wouldn't have any issues. That is, if you local gunsmith does a good job lol

FaRKle! Posted January 16, 2014 Report Posted January 16, 2014 I wish my MWS 16" barrel had come with a rifle-length gas system. Makes for a soft/smooth shooting rifle!
Dane Armory Posted January 16, 2014 Report Posted January 16, 2014 (edited) Reprofiling barrels is what Lance does. He is not quick BUT you will be impressed with it after he is done. It cost about $200 per barrel. Make sure this is what you want. It is easier to buy another barrel and put your old barrel on another gun. Edited January 16, 2014 by Dane Armory
beachmaster Posted January 16, 2014 Author Report Posted January 16, 2014 That barrel is half the weight of my barrel... I haven't seen another 16" rifle length barrel. I guess because Im still new to this. That is very very cool.

Robocop1051 Posted January 16, 2014 Report Posted January 16, 2014 SR-25 16" barrels have rifle length gas systems. Good luck finding one not attached to a rifle... and if you do, it'll likely cost >$500... AND I'm sure it'll weigh more than the FA bbl.
392heminut Posted January 17, 2014 Report Posted January 17, 2014 I had the heavy 18" barrel in my DPMS LR308 and had it turned down to .750 in front of the gas block. I didn't do anything behind the gas block though. At the same time I had my machinist buddy cut and thread the muzzle so I could put a brake on it. I re-parkerized it and put the gun back together, and as far as I can tell it hasn't affected the accuracy at all and it's not near as muzzle heavy. I'm very happy with the outcome.
beachmaster Posted January 17, 2014 Author Report Posted January 17, 2014 Did you weigh the barrel? I am surprised its 3.9lbs... thats seems heavier than what I would expect. In front of the gas block is .750 I believe, and its spiral fluted (for like 6", probably saving my 3 oz lol)
392heminut Posted January 17, 2014 Report Posted January 17, 2014 No, I didn't even think about it! Looking back I wish I would have weighed it before and after the work.
beachmaster Posted January 17, 2014 Author Report Posted January 17, 2014 I do that ALL the time... even when i promise before and after results, I always forget lol
