So I have a issue with the new Saber Tactical TRS rail.

I planned on buying it for my tensioned 800 barrel. A while back Elis told me he was going to order one for his compact impact. I had him order one for me at the same time too. When he got his he showed me his and told me about the barrel holding portion of the TRS. That when I realized something. I asked him to take a look at my TRS that he had and look at the barrel holder. There was only one and it worked for the stock diameter fx shroud only!

Of course he was like no biggie I will make one to fit your barrel too. What size is it?

Thanks Elis!

If you guys got the tensioned barrel and did not get a barrel holder that fits hit Elis up! For that matter if you have the TRS system and the non fx barrel shroud like maybe a hugget shroud just give him the measurements and he will hook you up.

Of course now I have to decide on what over the barrel bipod to get!

You shouldn't really need the barrel holder with the tensioned barrel I'd think? Certainly my 700mm 'pre official FX' Hein Frommann tensioned barrel has been entirely impervious to POI shifts etc, and it's been subjected to all sorts of bumps and temperature shifts etc.
Not that it hurts to have one to test of course.

But if you really really think that your tensioned barrel is actually that stiff. I dare you to try this. Put on a small/or no moderator on that ultra stiff barrel you have. Fire it at a point at least 35 yards away. Then get a heavier moderator like a emperor and aim at the same spot. Just the barrel without support and see what difference if any do you actually see. If it was actually that stiff there would be very little movement correct?

And it would be nice if it actually was stiffer than the ones you can buy. So after I wrote that statement above I decided to try it myself to see if it is stiffer and if the holder helps at all like you stated. This is all done at 34 yards. Since the barrel holder is already on the number one shot (red dot on right) was also my zero. I have a small hugget on the end. Number 2 shot is with the Emperor screwed on. It did drop some all the way down to the next bullseye. Now I removed the holder and screwd the hugget onto the barrel again. It shot high one bullseye above my bull I was aiming (red dot left). I screwed the Emperor back on and shot two times to make sure it was the same with the heavier moderator. It shot low on Bulls eye. So basically the way I see it the barrel holder cut the barrel droop by half and dramatically increased the stiffness.

Now if I actually was really smart I would have done the same test with the side retainer bolts in and hopefully get better results. 🤪

Sorry I may be misunderstanding here, but are you entirely sure the barrel holder hasn't just in effect pushed the barrel down when installed?
The poi went up without it installed with the lighter mod, the your zero poi is where it is by the barrel holder pushing the barrel into a position that aligns with the whole rail.
but with the heavier mod poi simply drops to the exact same height with or without the holder. If it had significantly changed the stiffness the poi at shots 4/5 should have been higher.
Anyway, with mine I don't get a lot of shift with different mods. Some for sure, as it's pretty much impossible to make a long barrel stiff enough not to move or change harmonics at all. That said Hein tightens that nut at the front of the CF tension tube WAY tighter that anything I would have ever dared attempt had I not seen him doing it, so that may well make the difference.

Anyway not trying to tell you not to use the holder or anything. Just an interesting topic I think. It'd be nice to see if your long range accuracy is better with or without it installed too.
Also how tight are the tolerances at the rail's attachment to the spine of the gun? Is there any wiggle room like on the OEM rail, that might subtly throw off alignment and cause downstream issues with the barrel/holder if you have to remove and reinstall it for whatever reason?

Cheers

Greg,

Yes, I think it was a bit late getting home and I was a bit excited to start testing with all the variables at hand. I do believe the barrel was pushed down a little. As POA vs POI was different. However POI with the barrel holder vs. without is still a lot smaller. I will have to redo the test later tonight afterwork or in the morning tomorrow.

The thing I am most interested in is when you install a over the barrel bipod. What happens to point of AlM and point the impact with a barrel holder? How stiff is the TRS rail in reality?

I am interested for mounting that "over-the barrel bipod" as well, currently I cannot use my 12 a clock Fortmeier, but also my closest dealer have no upper rail in stock me to try at least before ordering.

That's a very good question... Will keep out for any updates you post 👍🏻 keep well!

I just ordered a utg off of amazon to see how I like it. I will see how it works the Monday after next. But I have not been able to test much around the house. Been trying to get a tactacam to work with the scopes and not having fun but lookie!

And surprisingly you cannot see the mount when looking out the scope.

That's with a little hugget . This is with the Emperor compared to a compact with a 580cc tank.

Greg I will have to take a look at the tolerances again. I missed that question. I loosely installed the three bolts then slipped it over the barrel holder. At that time I tighten the bolts. I do know what you are talking about though because my scope rail has been knocked to one side with the factory setup and I believe it was off like 20 or 25 clicks!

Kind of what I'm afraid of happening with the barrel holder and the 'over the bore' bipod. Probably ok if barrel is centered and using a regular bipod, but not ok with over the barrel bipod. One of the reasons I don't care for bottle bands that go from the bottle to the barrel. Esp if another bottle band to bipod is also used. I will see at the range next Monday. Thanks for the link to the video!

Tolerances are about the same as fx as I suspect it has to cover a lot of error between each gun.


But as mentioned I used the barrel brace or bracket as a guide.

Yes and no. You won't have a issue with the gun tipping over. ...........

Asking because ........ every time I open the Leshiy2 stock to reload the mag, and and I am closing it, a 99% chance I lost the bubble. I am looking for a solution to make it self leveling, and that can be only with "above the barrel mount" and the gun to hang down from it by gravity.

Today I finally got to use the bipod and TRS rail. I kind of like it. Yes there are some issues. I wish the bipod would lock up the cant at any position I want, but it is just a resistance bolt. It won't stop the cant from moving. My monopod is on the right so the gun canted counter clockwise. The legs don't fold backwards. Like if your table was too short. I used both the Accu-Tac and the UTG bipod today and the UTG tends not to jump and rotate when fired like the Accu-Tac does. Is that better? Well it depends on how you hold the gun I guess.

Sorry forgot to take a picture of the over the barrel bipod at the range as well.

I also noticed I ran out of scope at 200 yards with the 20MOA TRS rail which is weird because my impact has 20MOA stock and my CT5 series scope is 34mm too! Hopefully nothing is bent. Edit the scope lid was touching so I removed it and I got some elevation back. Towards the end of the day I did change the rings out so the scope was more centered.

NOTE : I DID NOT HAVE THE FRONT BARREL SUPPORT INSTALLED DURING THIS DAY AT THE RANGE It was on but not pushed back where it was touching the rail system.

I was able to get a slightly smaller group with the Over the barrel bipod. But there was wind involved and I'm definitely not a great shooter. So it's just my point of view. Pretty good considering it is compared to the expensive bipod that is 3 times more costly.
