Gents:
Our TRG action wrench is finished! It will fit either the 22 or 42. It slides into the action and acts on the lug raceways for the full action length. It takes a 3/4" or 19mm socket.

http://www.kineticresearchgroup.com/products/wrench.php

Cost is 198. We've sold a number of these from the pre-orders but we've got some left. Our website payment should be fully functioning again tomorrow after an upgrade, or you can mail us a check. PM me for mailing info and so we can set yours aside.

The TRG barrel is screwed on ridiculously tight, so a stout vise and some rosin may be required for initial barrel removal. We haven't seen the glue used on the T3, just a lot of torque.

This product is of course only recommended for qualified gunsmiths/armorers/others qualified to install barrels. Be sure to check headspace on any freshly installed barrels.

Okay thanks!
Justin

Would a 1/2 inch drive breaker (24") bar not be enough to break it loose? What do you guys use to loosen it?

Looks good btw!

Great job.

Re: New product: TRG Action Wrench!

Justin, is this ya'lls diabolical plan to confiscate the entire sum content of our net worth? Seriously, my wife is not going to send you a Christmas card if you keep coming out with stuff that we're just gonna HAVE to buy!
Where is the checkbook?

I see.

I guess damaging the factory barrel when trying to separate the action is a usual thing. Really no biggie... the barrel is going to be replaced anyway.

I'll get one of these for sure.

Re: New product: TRG Action Wrench!

Shooter5, Muuuuwhahahaha! PM me before you send funds.

Pupdawg, you shouldn't have to damage the factory barrel, you just need to buy or find someone with a better vise than the Wheeler one, It doesn't have enough surface area and the wood blocks don't match the TRG barrel taper that well. Not a knock on them by any means, other internet comments I've seen suggest the TRG barrel is way above and beyond the normal factory barrel tightness. Then when you screw a new barrel on, just don't tighten it as much so you can use the Wheeler vise if you have that one.

If the barrel vise becomes an issue, we'll make one, but there's good vises out there already. We may do a set of inserts that matches the factory barrel taper, however.

Also web purchasing is up and running so I'm modifying my earlier post.

Thanks for the clarification.

Again, great job with the TRG stuff!

Re: New product: TRG Action Wrench!

At first I torque my barrel on the TRG with the same ft.lb that AI recommends on, which is 100 ft.lb and now I have worked my way down to about 70 ft.lb and fired about 300 rounds without any changes. This is not a recommendation, it´s simply what I use when I change barrels on MY trg.

Re: New product: TRG Action Wrench!

Do you apply any heat to the barrel for removal for the first time?


Massoud, I recieved mine, and thank you very much!
I appreciate it!

Re: New product: TRG Action Wrench!

SFT, after the first time, it's a quick process. Just remove the cheekpiece, clamp the barrel, swap the bolt for the wrench, and turn. If you have a portable vice you could do it at the range no problem. We're going to look into vise solutions eventually to see if there's a vise that you could clamp to a shooting bench or tailgate easily.

Stefan, glad you got it and thank you for purchasing! I applied heat but it's not like the Tikka with glue in the threads, so if you can avoid it, then skip the heat. The phosphate finish doesn't seem to like heat.

Re: New product: TRG Action Wrench!

Gents,
With the posts in this thread and the pm's asking about barrel removal, I figured I'd post my experience.

Disclaimer: Only those qualified should be installing barrels, and check headspace when installing, and don't mess up your action and blame us

The first time I tried to remove the barrel, the Wheeler vise just couldn't keep the barrel from slipping, even with rosin. So then I incororated a second vise, which was on our small mill here.

The Wheeler vise comes with several oak blocks for clamping barrels, I put one set of blocks in the mill vise so that the long face of the blocks rang along the barrel to give the most surface contact. Then I tightened the mill vise to a ridiculously tight amount, one of the blocks actually cracked a little. Then I put the Wheeler vise on the barrel as close to the action as possible, and I clamped the wheeler vise to the mill table. Again I used Rosin, then tightened the hell out of the Wheeler vise.

At that point I inserted the KRG action wrench, put on a 19mm socket and a socket wrench, and an 8 foot length of steel conduit was my breaker bar. Well all this did was destroy the socket wrench (3/8" drive). I had another one, this one better quality, but I destroyed that one too (also 3/8" drive).

At that point I was out of ways to turn the action, but I found I could use the Remington 700 action wrench with one side flipped to engage the flat on the KRG wrench. With an 18" breaker bar, the barrel still turned in the blocks, so I applied some heat to the action around the threads, then I gave it a quick snap and it loosened with a loud crack. What I found was disheartening, but my rifle is 3 years old at least, and has seen some inclement weather.

It looks a lot rustier than it was, a couple minutes with a wire brush cleaned it up.

Note this particular KRG action wrench is not phospated or sand blasted.

Re: New product: TRG Action Wrench!

Sound like it gave up one hell of a struggle.

Mine weren't as hard to unscrew as yours but it turned in the wise nonetheless and this is what my barrel look like after the removal:

But with some regular gun oil and some scotch-brite and some rubbing it look like this:

Mine too had some rust on the threading and my gun were only 3months fresh out of the factory when I removed the barrel.

Re: New product: TRG Action Wrench!

Looks like I need to pick one of these up soon. Hopefully mine isn't as stuck as everone else's, hahah!

You plan on keeping these in stock?

Re: New product: TRG Action Wrench!

johndoe, I'm not sure as I've never actually seen a 21 or 41, but I kind of doubt they changed the bolt, as the TRG-S bolt is the same. Do you have a 21 or 41, maybe you could post a pic of the bolt?

bm11, we still have some left, we'll do a second production run before we're out of these so at most we will go a week, maybe two without any.

Thanks,
Justin

Re: New product: TRG Action Wrench!

Justin,

I don't need it now, in a month or so. Just waiting for the Christmas season to blow over, plus, have to get the new barrel in first anyhow.

-Bob

PS- You should get a breaker bar!

I wonder would impact wrench help or be useful?
Basically barrel mass inertia should help a bit when opening and prevent slipping.

Thanks for the information! Rust is a natural loctite

The phosphate finish is a nice touch!! I'm almost afraid to use it and mess it up!

Re: New product: TRG Action Wrench!

It’s about time that someone milled and started marketing this tool. Its the first step to bring the TRG into the realm of the Rem 700..

Re: New product: TRG Action Wrench!

To everyone who has used this product- has it proven to be that TRG's have a standard headspace like AI products? I made this assumption and bought a new takeoff barrel recently, and I am planning on installing it myself. I of course will check the headspace, but it would be good to know if it could be an issue.

Thanks,

-Bob

Re: New product: TRG Action Wrench!

Bob, the TRG headspaces differently than an AI from what I understand. AI's headspace off of an inner collar, like a Mauser. This makes headspace on the AI very easy, a barrel is chambered for a certain amount of protrusion of a go gauge, for example .127" from the barrel face on the Badger 2008 (similar to AI).

The TRG headspaces off of the barrel shoulder like the Rem 700 or many others. So it's not as easy to just call up and order a barrel like for the AI. However, it can be done with very precise measurements from the barrel shoulder to the barrel face, then from the barrel face to the protrusion of the gauge.

Even better would be to measure the action, from the front of the action to the face of the bolt, then the smith can factor in a litter clearance between the face of the barrel and the front of the bolt, then cut the chamber.

Probably most gunsmiths would want the action once but after they took good measurements they should be able to cut you barrels on request.

Justin </div></div>Justin- my question is this: should I be able to spin my factory TRG barrel off and spin another factory TRG barrel off a different rifle on, and be good to go?

Re: New product: TRG Action Wrench!

JL-Impact wrench would be great, I didn't have one though.

-Stefan73, just give it one scratch to get you started, then you won't mind others, haha.

-EM, we'd love to see the TRG like a 700, but I think the cost is a bit too high to become as common. But if we get a good aftermarket established, guys will start buying them over custom 700's. The Tikka T3 should be able to compete with Rem on cost though, but again, need that aftermarket support.

Re: New product: TRG Action Wrench!

Bm11, not necessarily, you'll have to check headspace and may have to trim the shoulder back or deepen the chamber a bit. If headspace is too tight, it's a simple matter to grab a chamber reamer and take a few thou out by hand. If headspace is too loose, you'll need a lathe.

Re: New product: TRG Action Wrench!

I would check it first before sending off. Because you never know.

Here's something about headspace that you don't hear too often, a gun that a couple thou over is not going to blow up when you fire it, generally. For example, a 308 Win go gauge is x.x long, the no-go gauge is about .004 longer.

But a 7.62x51 go gauge is the same or a thou longer than the 308 no-go gauge, and the 7.62 no-go is another 4thou longer. Many people have shot 308 ammo in a 7.62 chamber and lived.

Another thing to think about is the existence of a field gauge. It's around .010 longer than a go gauge. I think the military uses these but I'm not sure, I never saw them. Anyway, if your bolt closes on a no-gauge, as a last resort you can try a field gauge, and if won't close on a field gauge, you can use it if you really have to (hence the name "field").

Disclaimer, I am not a certified armorer or gunsmith. Don't take my advice as the absolute truth. I have designed and built a number of rifles, but you should look into all this and make your own decision.
