jdknotts1 Posted January 26, 2012 Share Posted January 26, 2012 5.56 20" HBAR from Bushmaster rifle 1:9 twist Muzzle not threaded <500rnds through it I picked up this barrel for $20 from a friend at work. Figured what the hell. Question now is, what should I do with it? I'm currently using a LE 6920 and everyhting I'm reading says a 18-20" bbl with mid/rifle length gas system is what works best for 3gun. Ok then. Have the barrel, what should I do with it? Is it worth doing anything to? I was debating on having it cut down to 18" and threaded for a muzzle break. Is this worth it? Should I leave it at 20"? Which ever one I decide to do, will I need to balance out the weight to the back end? Is this barrel too heavy to use for 3gun one way or the other? Is it feasible to have it fluted to cut down some of the weight? I don't plan on spending much to get all this done. A friend of mine thats a smith will cut and thread it for $45.

landshark45 Posted January 26, 2012 Share Posted January 26, 2012 Cut it and thread it for the $45. You can always buy a dedicated barrel when you have the extra cash. Like it is now but threaded it would be a really cool Iron sight build. It can't get cheaper only more expensive. Link to comment Share on other sites More sharing options...
ajg308 Posted January 26, 2012 Share Posted January 26, 2012 Don't cut it till you know exactly what you want. Bennie is back to a 20 inch barrel for 3 gun. And he is using 53 bullets in it. Just a thought. Link to comment Share on other sites More sharing options...
jdknotts1 Posted January 26, 2012 Author Share Posted January 26, 2012 (edited) Keeping it as a 20", will I need to build up the back end to balance it out? Currently just a stock carbine lower. The barrel is pretty heavy Edited January 26, 2012 by jdknotts1 Link to comment Share on other sites More sharing options...
mpeltier Posted January 26, 2012 Share Posted January 26, 2012 (edited) If it were mine, I would send it to ADCO and have them turn it down to .750 and thread it. They will re finish it as well. Leave it 20". I also am back to a 20" for my 3 gun rifle. And I have several guns with carbine lowers, but my 20" game gun has a rifle stock (Magpul prs) that balances it nicely.

Stuck in C Posted January 26, 2012 Share Posted January 26, 2012 I have what is probably the same barrel. I left it at 20" and paid a gunsmith friend $20 to thread it for a comp. I too was worried about how heavy it is and considered having it turned down or fluted, but I was broke at the time so I left it as-is. It actually balances just fine and I don't even notice the weight when I shoot it. And it shoots darned good... Link to comment Share on other sites More sharing options...
mscott Posted January 27, 2012 Share Posted January 27, 2012 I had my 20" HBAR turned down to govmt profile by ADCO and like it so much better. Leave it at 20", but I'd try to take some weight off of it. It's not necessary, but I do like mine. Link to comment Share on other sites More sharing options...
Lead-Head Posted January 27, 2012 Share Posted January 27, 2012 How much is it to turn down a barrel, cut it and thread it? I only wonder how cost effective all that gunsmithery would be since you can get a new bushmaaster gov't profile barrel from them for $215. You can get the entire assembly for $235. Just a thought.

Check out their web page. http://www.bushmaster.com/products.asp?cat=7 And the cost is my issue. I can get a JP match barrel for $300 or so bucks. I paid $20 for this one. Might invest up to $100 all together on this. But even then its a gamble. No clue how it will shoot. Also, the weight issue. Not going to pay to have it turned or fluted. Thats why I'm wondering if I should have a couple inches cut off. Link to comment Share on other sites More sharing options...
Big Bore Posted January 27, 2012 Share Posted January 27, 2012 20inch barrels are back. Wow, I didnt know they were out. I would thread it and shoot it. Burn it out getting started and then move on to whatever you feel like after. Link to comment Share on other sites More sharing options...
J.D. Larsen Posted January 31, 2012 Share Posted January 31, 2012 Would there be any problems associated with cutting a 20" barrel back to 16" to run the rifle length gas system? Link to comment Share on other sites More sharing options...
assaulter Posted February 1, 2012 Share Posted February 1, 2012 You could probably sell it for $150 and put that toward the barrel you want. I'd keep it at 20", shoot it for a few matches, then decide if it's worth having it turned down. Link to comment Share on other sites More sharing options...
Jadeslade Posted February 1, 2012 Share Posted February 1, 2012 Matches have taken to putting in some really long targets and that is why 20" is back. Flashers won't flash at 450yds if there isn't enough wham. More velocity equals more wham. Get it threaded. Tell us what you think. I have wondered the same thing.

I've heard of guys doing it. If I would have it cut down, it would probably only get cut down to 18". I talked to my smith over the weekend and he said it would end up being about $150 to have it turned down. I can't see how it would be worth it honestly. I'm probably going to get it threaded and keep it at 20". If someone would really buy it for $150 I'd probably be up for that. Link to comment Share on other sites More sharing options...
