Title: After installing new barrel....
Post by: nc shooter on December 18, 2011, 09:09:48 PM
I posted a while ago about a bent barrel on a remington vantage 1200, and that I would follow up after installing a new barrel. So heres the thing. I install the new barrel, and now the new barrel is pointed downward about a 1/4 inch.

Here's how the first barrel got bent and how maybe it has effected the new barrel:

I altered the trigger assembly so it would be better because everyone knows how horrible the triggers are on the b19's. That caused the rifle to fire even if its cocked. So when I wasn't there, my brother was using my rifle and for some reason pressed the trigger while it was cocked. It snapped the barrel back in place causing it to bend upwards about 1/2 an inch.

New barrel is now pointed downward about 1/4 inch.

Anyone ever have this problem? Or may know of a solution?

yeah the barrel was fully cocked down, the trigger pressed, and the barrel snapped back up into place with the force from the spring

Using a vise, some padding, and some patience, you can bend a barrel back straight.  Put it in the vise so that you are only bending the barrel itself, not where it is pressed into the breech block.

wouldn't happen if the simple rule was followed...never pull the trigger unless you are sure of your target.

hope no serious damage was done.

John, thank you very much! No more barrel droop!

You're kidding. You actually did that fix? That's great. I thought long and hard about it, lost faith that I could do it right, and instead threw $$ at the problem by buying the Burris Signature rings and inserts which canceled out my droop.

Well I was thinking long and hard myself, but I couldn't figure out a solution. Then you posted that link. I looked at what the guy did, and his solution seemed very logical to me. After finishing it, it made me think that the new barrels are made that way on purpose. It's better to file off the extra metal till there is no droop rather than risk having the barrel pointing upwards. That would be harder to fix. But yeah thanks to you! And maybe I would buy the rings and inserts myself but it's only a $120 Remington Vantage, so I wasn't too worried if I messed it up. This is the rifle that I'm learning everything on, including my first home tune.

Way to go !!  It's great when your intuition is validated by good results.  The best way to learn.
So you are still getting good metal-to-metal contact on lock up?  Have you had a chance to check accuracy yet?

Thanks Lloyd! Metal to metal contact is pretty good, that is after I filed it in the necessary areas. The sharpie trick is the key in making the contact be flush, doing it pretty often to avoid going too  much with the file. I used a dremel tool on the lowest speed setting using a very fine wheel. Then I used an even finer polishing wheel and made it smooth. I do realize that  using a dremel tool is definately not the ideal way to go, but I took a chance and some extra time.

I haven't checked accuracy yet, but I can't wait to find out.
