We have both options, you just need to choose the correct one. They are not interchangeable so make sure you order the correct one. The M3 option is for the Tensioner WITHOUT the clamp. The other option for the Tensioner is for a rifle WITH the barrel clamp.
If you have any questions just give us a call and ask us. We are more than happy to help you out to make sure you get the correct product the first time.

An unfortunate side effect of tensioning the carbon fiber sleeve is that my POI shifted more than 6 inches to the left on my .25 Impact M3. I was shooting at a distance of 57 yds. After I had finished indexing the STX heavy liner I purchased a few weeks back and got it zeroed in to my satisfaction, I installed the BC barrel tensioner but not the shroud. I figured there would be some shift but was really disappointed at how much the shift actually occurred.
I did try indexing the carbon fiber sleeve and it helped some. I got about a 2 inch shift back to the right and about an inch up on the POI.
I think I'll try backing off the tension nut a bit to see if that helps but then I might lose the benefit of the stiffened barrel.

I am curious if this shroud and tensioner kit will remove any POI shift from my Maverick. I have to "baby" my Maverick and be very careful how I handle the gun. If I accidentally bump the barrel, lightly mind you, the POI will typically shift. Mine is a 600mm barrel with carbon fiber sleeve.
I have to be very careful when I transport the gun since I don't have a hard case, just a nice padded bag case. My hope was this kit would make my gun significantly less sensitive.

That is to be expected. You are changing the harmonics with the barrel and this will typically change the point of impact.

The question I have about the tensioning system is ?
Over time (100's or 1000's of shots)does the barrel move forward ?
It seems like it is demanding alot from the single barrel clamp screw that doesn't have a detent to go in ?
Thanks Brian

Hello Brian,
We have been testing them for some time and have seen no damage, as well we haven't heard anything from the customers that have the units currently. There is always the point of tensioning the kit to much that will cause damage to the barrel. And that is why we mentioned in the video to not go to the extreme.

It interesting that your poi shifted to the left. Mine shifted to the right but only about a half inch at 50 yards. I talked to Dale at varmint Knockers and he said he noticed a shift to the right on tensioned barrels although not specifically the bullet central ones but they all work the same. 6 inches at 50 yards seems like a lot. How much tension are you putting on it? What do you mean by indexing the the carbon sleeve?

We do have the ability to make them for the MK1's.
You are able to click on the drop down box and select the MK1. Then just select the length and you are good to go.

Looks great!We are proud to introduce our line of Carbon Fiber Tension Shroud kits! These units will work on most FX rifles to create a tensioned barrel system. These units will help increase the stiffness of the barrels on many of the FX rifles as well as looking great!

We are also excited to introduce the much anticipated Tungsten Hammer Weight! We will have two weights available to help with your tuning needs. There will be a Standard weight hammer weight of 223 grains, and a Heavy weight hammer of 254 grains! This will help push your rifles to new limits and achieve never seen before power. This will allow us the shooters to push heavier projectiles faster!

BC Custom - Tungsten Hammer Weight - Bullet Central
The BC Custom Tungsten Hammer Weight is made from 80/20 tungsten copper alloy. This weight will allow you to set your regulator pressure between 125 bar to 185 bar (with standard 50mm hammer spring – .3mm wire size), thereby providing higher velocities, especially when shooting heavier...

In theory your kit "should" make my Maverick less sensitive to changing POI correct? I try to be very careful with it, and most days my gun stays locked on zero. I'm not expecting it to completely remove the possibility, but hope it will make a noticeable improvement. I'm really close to pulling the trigger on purchasing your kit for my gun, plus I love the look of the carbon fiber! Thank you for answering my questions, I really appreciate it!

That is the idea behind the system along with improving accuracy as well. Like mentioned above, there will typically be a zero change. Depending on the amount of tension that you add to the unit will change where the pellets land. Every rifle is different so there isn't a torque value we can give people.

A small POI change after installation is no big deal for me, and no surprise. Anytime I basically touch my barrel my POI changes lol. I'm just hoping it helps stiffen up the barrel assembly. That's my main gripe with my Maverick, that it's a bit "fragile". Otherwise it's a tack driver with plenty of power.

I just remembered that if you remove the top rail and loosen the barrel block slightly before tensioning the barrel and then retightening the barrel block after tensioning you can minimize the big side to side poi shifts. That might help in your case with a 4inch shift.

I rotated (indexing) the sleeve to 3, 6, 9, 12 o'clock positions and that does effect the POI much like rotating barrel liner, I put a small mark on the tip of the carbon sleeve to see what position it is at while I rotated it. It is at the 3 o'clock position while the barrel liner is at the 9 o'clock position.

I didn't loosen the barrel block, but I decided to realign the scope rail ever so slightly. I loosened the front screw and the two rear screws, and shifted the back end of the scope rail to the right about half a milimeter. The front screw acting as a pivot point. That slight shift produced a 2.5 inch shift back to the right. The final shift to the left after indexing/rotating/tensioning the carbon tension sleeve and measuring with a caliper was 3.4 inches not 4 inches I stated before. So the net shift is slightly less than an inch now. I fine with that.
You can see from the photos, the rail is now slightly out of alignment on the left side but looks in alignment on the right side.
Third picture shows the sleeve and shroud installed.
I do wish Bullet Central offered the assembly in a matte finish rather than a glossy finish.
After all that work I got a half inch group with Predator GTO .25 16.5gr at 57 yards. Happy with that!
Not sure what speed I'm shooting the pellet at since I accidentally shot and destroyed my Combro barrel chronograph a few weeks earlier. I didn't align it properly and a .25 Hades blew it apart.
