External, and it has to grab it TIGHT. I used a generic piece originally intended for Savage actions that I got from Northland, and it worked well... but eat your Wheaties and expect to spend some time cussing at it, 'cause the factory barrels are, uh, snug.
I use a Wheeler #1 external with a breaker bar to remove Tikka factory barrels the first time because they are so tight.
After that all you will need is an internal wrench to torque another shouldered prefit barrel on or off.
Be sure to use anti-seize on the threads and shoulder and check your headspace with a go-no go.
I use the same external wrench. Clamp the barrel in some v-blocks and a phone book in the hydraulic press, give the wrench handle a good smack with a mall and they pop right off. It’s the shock that knocks them loose, not the static torque. Remember to clamp the wrench right up by the action/shoulder.
Two steel v blocks and a barrel. The phone book keeps the v blocks from marring up the barrel. Cheap easy and effective. Good use for that phone book no one uses any more, a Dennis Kirk or midway magazine works too lol. Once you get the Sako Finland tight barrel off you can resume using wood blocks, that first one is often toight.
Pretty sure we've used a crescent wrench, lol. It's nice to have a couple good flats on the action. I'll 2nd/3rd others saying that the factory barrels are on there VERY tight.
There’s a big flat on the bottom, match that to the flat on the wrench and let the v block do the rest of the work. Take the rail off if you have one on it.
Any of you guys in the Houston Area that have the tools and can help me pop the barrel off the three tikka actions I have one weekend? I sure don't mind paying for your time.
Put it barrel down in a vise and shoot some Kroil into the action where the barrel threads in. Add Kroil every day for a week. Mine came loose and had Kroil halfway down the threads.
I use a Brownells steel barrel vise, 1.150" aluminum vice barrel collet, and lead sheet to make a perfect fit. A touch of powdered sugar to grip the barrel. Then I use a Brownells Universal action (outside the action) wrench. I've popped off 3 Tikkas and a Sako TRG this way. No problems, no damage to the barrels. I have put a thin piece of steel bar stock between the action wrench and the top of the Picatinny rail to prevent marring of the rail.
Here's my story. I bought the viper barrel vice, the same outside action wrench (from Midway) as JGR1953 has shown in the above picture. And I bought an inside action wrech from southern precision rifle (bughole.com). I didn't mount the viper vice when i removed the barrel as I wasn't saving the barrel, so...
Step #1 I sprayed kroil inside of the action on the threads and let it soak for a week. Barrel down so the kroil would flow down the threads.
#2 I torqued the outside action wrench too the action (side to side not top and bottom) and I clamped the barrel into a small regular bench vice I had at home (don't flame me, I wasn't saving the barrel ) and tried giving the action wrench handle a couple of whacks but the vice wasn't strong enough to secure the barrel and it spun in the vice and didn't seem like it budge the action any. At this time I stopped and took the action/barrel to work were we have a large bench vice the next day, all the while the action wrench was still bolted too the action. I clamped the barrel in our work bench vice and on the first attempt of grabbing the action wrench handle the action just started to unscrew. So I stopped and removed the action wrench and just unscrewed the action by hand. Not sure if the previous whacks helped? But it didn't take too much effort to get it moving. If I intended on saving the barrel I might have tried with the viper vice. Now I have the proper tools to install the new barrel, viper vice, inside action wrench.
31mm cheapo Tecktonik? box wrench with a cheater off Amazon did mine fine for $20. The nice PVA action wrench I bought first sheared long before the barrel broke even with heat, Kroil, freeze, etc. using a Brownells barrel vice.
I used the Midway barrel vice for a Remington 700, reversed the bottom part so it was flat against the receiver, and ran a couple laps of skateboard tape around the action.
It came off (and the other one on) rather easily without marring the action in any way.
I got a Wheeler #1 action wrench, Mechforce barrel vise, and a Tikka inside wrench coming. I will be pulling a few barrels this weekend it looks like. I have a big C-type vice and a press so I could have made some V-blocks but I went ahead and grabbed the barrel vise anyhow.
My advise is, use an external action wrench to remove barrels (especially factory) and an internal action wrench to install them. Reason being, you'll likely need far more torque to remove a barrel than install one. An external action wrench will most effectively transfer the torque to the barrel tenon threads than a 8"-10" long internal action wrench. Flip side, when installing you will want to use a torque wrench - for that you'll need an internal action wrench.
External action wrench to remove factory barrel - internal to install. That said, I'd recommend Bugholes action wrench (http://www.bugholes.com/product-p/t-bug-aw.htm). Greg is great to deal with, he recently built an Accuracy International/Badger M2008/2013 action wrench for me which I'll post on shortly. No better action wrench or customer service out there. @Bugholes
It's partially the camera angle, partly the way I cut it. I start the plunge slightly wider to allow the curl to not get caught up in the tight confines of the cut. In the first photo you can see the area of a slightly wider cut.
Hopefully this is the right place to ask. Now that I know what tools to use on a prefit barrel with a nut, how would you install say a proof research prefit carbon fiber barrel? I they call the barrels without a nut a shouldered barrel?
This is the way I do my carbon barrel but I'm sure others have their own way of doing it....
You want to stay off the carbon wrap and just grip the steel shank.
My Davidsons vise is made like your Viper so I just cut and sandwich two pieces of leather on top and bottom and use just the two front bolts on the vise then I coat with powdered rosin.
Lock the barrel in and screw your action on and insert the internal wrench and use whatever ft/lbs of torque you want.
I use 65 to 70 ft/lbs on my Carbon6 per their recommendation and then check my headspace with my go/no go gauges.
Ok guys. I pulled a factory barrel on a t3x ctr and a t3x lite. I was prepared for a battle considering all I read about Tikkas. I grabbed the barrel near the action with my mechforce barrel vice with the wheeler #1 action wrench on the action. I hit the handle with my hand and the wrench turned. I thought the barrel spun in the vice. Nope. The action broke loose and i unscrewed it by hand. I put the ctr in the vise next and hit the wrench with my palm again and it broke loose and the action spun off by hand.
I could have saved the $53 on the wheeler wrench and just used the Tikka inside wrench I have. Taking the factory scope base off the ctr proved just as easy. Screwdriver in the screw and turn. No heat required.
Now that I thought about it for a minute, I wonder if the people having a hard time removing the barrels are the T3 models? As the barrel that wasn't too hard for me to remove was a T3X model? And I have no experience with a T3, Just thinking out loud.
Maybe so. Hopefully some other guys chime in. Both of mine were just a quick pop with my bare hand. No heat. No cheater. An inside wrench would have easily done the job.
I read on another site somewhere where guys were making a big deal over the Tikkas and someone chimed in and said Tikkas where the easiest factory action to rebarrel. I figured he was talking tough until I unscrewed mine.
The guys at LRI told me the problem is that the T3 barrels are all over the place for torque, from 80 ft-lbs to 140. It’s like it depends on the person who was screening barrels on at the Tikka factory on whatever day.
I have one more tikka t3x action that I may pull the barrel. This one is carbon and not stainless like the other two. When I do it I will let you guys know if there is any difference.
I pulled the barrel off the carbon tikka t3x ctr. Same thing. A couple hits with my palm and the action broke loose.
Mechforce vise is$90 shipped. I recommend it. Throw the leather away as soon as you get it though. Wrap the barrel with a piece of paper. No marks even on the blued barrel.
I probably had a double wrap. I doubt it matters. Just put a couple wraps and bite down on it in the vice. No marks and did not slip.
i didnt have headspace gauges so I used the tape method and the headspace seemed to check out. I put the rifle in a led sled and tied down the front end. I used a long piece of para cord looped around the trigger and shot all of them from about 8’ back. Lol. All is good. ? I knew the led sled would be good for something.
ok, the "external" action wrench, that's the black thing with the two bolts (item #2 from top to bottom), right? you bolt that around your action (left and right sides)? almost doesn't look like it would go wide enough.
if not keeping the barrel, how about vising up the action and trying to spin the barrel with a pipe wrench?
a pic of that external action wrench with an action in it would be very helpful. thanks!
