Useful Resources for Tiberius Owners

Hey all,

Theres been a bunch of threads in the past month about "My first tiberius pistol" that were asking about taking the pistol apart, mods for it, etc... And thought it might be beneficial to make a thread people could simply look at, instead of asking the question again and again. The internals are pretty different from most markers, so it's understandable.

Before I go any further, the phone number for TA is 260-478-2500. They're super helpful and in my experience will send you parts for free 9 times out of ten.

All manuals for Tiberius markers can be found here:
Manuals | Tiberius Arms Paintball Markers

(Probably the most helpful but by all means watch the others, there's more later on talking about first strike)

Tiberius Arms Tech Talk: Bolt Push
In this video, Pete shows us how to check if the bolt is pushed when your marker won't fire. The reason for this is that the bolt will not catch the sear if already behind it during assembly.

[CENTER]Tiberius Arms Tech Talk: Gun Body Assembly
In this video Tiberius Arms shares some tips and techniques as they walk you through how to disassemble and reassemble the gun body components.

Tiberius Arms Tech Talk: T8.1 Handle Removal and Installation
This video shows how to remove and install the handle from the T8.1 pistol. The same process is used to remove and install the handle from the T9.1 and T8 and T9 models.

Disassembly of the X.0 Series: DskIGoKEkrXE1o6zWWIVmw9JI]Tiberius Arms T-8 break down - YouTube

While the above video is great, it doesn't give you any info whatsoever on the most daunting piece of the marker; The trigger group and assembly. This video highlights this:]t-8 Regulator - YouTube

Another part of the marker that isn't shown in the main disassembly video is the "engine", bolt, or back block assembly. This video really only applies to the x.0 marker, but something can still be learned for the X.1 series: DskKxJLcLd3FUBFy_b2nNTeEB]Tiberius Arms Air Chamber - YouTube

Capping off the disassembly videos, is the one highlighting the bolt push. I think i can safely say this is the #1 reason Tiberius markers fail to function, and it's a simple fix. Make sure to push the bolt forward while disassembling:

Dissasembly Of the X.1 Series:

So im not sure what happened with Tiberius Arms posting Youtube videos, but they didn't continue that through the .1 series. Two guys, 'Modern Intel" made two youtube videos walking you through it. It's not that different from the X.0, but still nice to have correct resources.

Part 1: DskIkLVUOe9oTYvDsh0Pdtzjy]Tiberius 8.1 Disassembly (Part 1 of 2) - YouTube

Part 2:]Tiberius 8.1 Disassembly (Part 2 of 2) - YouTube

Tiberius 4.0 Dissasembly
Also done by ModernIntel, I've only skimmed the first few minutes of the video but it seems fairly complete. Im going to be searching for an exploded parts diagram for this in the future.

Bolt Polishing

This is another common thing that is asked about around here, and i thought i'd include it. Lord Odin made a great video guide to doing it, so ill put it up. He covers everything in detail, great video: DskLCkK_cCO3MOhZOdqR7VyXK]How To: Polish T8/T9 Internals - YouTube

Conversion To First Strike

OK, while i've never actually seen someone asking about this, i figure its worth including. This video covers converting your marker to shoot FS rounds (X.0 series) in pretty good detail: DskKiHP5bxtX9tez72eE6pvRh

Tiberius Arms First Strike
The Tiberius Arms First Strike paintball round is the first truly significant break through in paintball ballistics. Utilizing a combination of aerodynamic shape and fin stabilization technology, First Strike projectiles maintain their velocity longer. The result is 50% greater range and unrivaled accuracy. All current Tiberius Arms markers come equipped to fire First Strike and traditional paintballs.

Remote Line Install

I know that at least I was confused with how this worked at first, so I'm including this too:]t8.1 remote adapter install - YouTube

T8.1 Pistol Remote Adapter Cobra Coil Push Button Remote Install
Pete explains how to remove and replace a standard quick disconnect fitting from the T8.1 Remote Adapter with the Guerrilla Air Cobra Coil male fitting.

T8.1 Remote Adapter Install Video Part 1
Pete explains how to install the T8.1 Remote Adapter. The first two steps is to replace the regulator body plug with a regulator body oring and replace the standard co2 stem with the solid co2 stem.

Magazine Dissasembly

This first video is only for the X.0 Magazine, and the X.1 magazine differs quite a bit from it. It's pretty hard to mix them up, as they look pretty different: DskKg80nYRh8B9tRM7I2fVYrK

This second video here is for the X.1 Series. It's not actually made by Tiberius Arms like the others videos are, but its still good information: DskLn7WLjKiJITnIV5r2nC8Ap]Tiberius 8.1 Magazine Disassembly - YouTube

New update thanks to UV Halo for compiling this, he did a great job.
Oring guide:

So, I figured I'd tear down mine, and note the sizes/types of o-rings in the gun. I've provided the name/number in the manual, and the names on Rockstar Tactical. So, when you have an o-ring fail, break out your manual, and identify the page, and drawing number. Then, you'll see the Tiberius part number and, the o-ring size/type.

XXX-PXX denotes white/clear o-rings (Polyurethane)
XXX-BXX denotes black o-rings (Buna Nitrile)
XXX-X70 denotes Soft o-rings*
XXX-X90 denotes Hard o-rings*
To test hardness between two o-rings of the same size, drop the o-rings on a hard surface. The hard one will make a crisper sound. Or, you can try bending them.
