Tips for sa-8 owners
 
ok so if you havn't already seen this thread LOOK AT IT ALREADY.
Tiberus Pistol $99 - mcarterbrown.com

this is the x7og thread.
new $99 tac-8

or the a5og thread

new $99 tac-8

this is a sa-8
https://i50.tinypic.com/25rmolu.jpg

the sa-8 is 99% the same as a t8 but it has some differences. it's velocity is turned way up, the barrel is longer, it comes in either blue or orange, and the velocity screw is supper sensitive.

this quote is true to an extent. you won't jump 90fps with every turn. just when it is at 240 or so.

DIALING IN YOUR SA-8

this is the most critical step. your sa-8 will be shooting at 350+ fps. out of the box.

what you will NEED.

a CRONOGRAPH this is VERY IMPORTANT. If you don't own one either try to borrow one(like I did) or go to your local field and use theirs. this is to be safe and get your efficiency up to 2.5 mags (20 shots)per 12gram.

a 3/16 allen wrench

some paintballs. caution as soon as you fire paintballs you have voided your warrenty. therefore I reccomend that before you use paintballs you load up both mags with the blue practice rounds that came with your sa-8.these will not void your warrenty so if there is a problem with your gun you can still send it back. after the first 2 mags fell free to void the warrenty if you want to.

12grams (btw all of the 12grams in the 2nd picture were used cronoing the gun)

both mags.

prehaps the t8 manual. https://www.tiberiusarms.com/document...ual_May_08.pdf


to addjust the velocity turn clockwise to increase the velocity or counterclockwise(left) to decrease the velocity.

the back of the gun

if you find that your gun isn't fireing either you are out of co2 or the velocity screw is too loose. to correct this pop the mag out turn up the velocity and then reinsert the mag. don't try to turn it up while the mag is still in the gun(if your gun isn't fireing that is. if it is fireing then feel free to turn it up while the mag is still in the gun just make sure to keep the gun pointed in a safe direction at all times.)

crono your gun down to 270fps.


IMPORTANT
now you are dealing with co2 here so when you finish the first 8 rounds DON'T immediatly load the same mag up and shoot is again. the co2 will be very cold. cold co2 means low velocity,low pressure,and fewer shots. so use the other mag instead and/or use the palm of your hand to warm up the cold 12gram.



also co2 tends to spike in velocity so make sure that is is low enouf to stay under 300fps.


I havn't tried this yet but I will soon.

In regards teo the efficiency, I would turn you velocity down a bit and see if that helps. Also, you can try polishing the internals, I've got about a 4-5 shot increase from that. How To: Polish Internals - Tiberius Arms Forums


over all I am pleased with my sa-8 I havn't gotten to use it in a game yet but I will soon.


now if you own a sa-8 (or a tac 8) and have a tip for others please POST IT UP.

soooo also ... not sure if i read this part...

but cool0 you may want 2 add 2 things...


1. shooting " A " Paintball voids your warranty...

2. DO NOT CALL TIBERIUS!!! these were sold to pepperball and no warranty to Tiberius!!!!!!!

3. The bolt has been shown to be like the T8.1.... you will need to buy the 8.1 mags or modify them.... also barrel.. you can use the 8.1 or you can dremel out the ( shape for first strike rounds.....

just look through the 80+ pages... towards the 70-80's you will find it....

going to morrow to get more 12oz....:ohya:

Those practice rounds look like they were made by Perfect Circle Paintball. I wonder what those are filled with.

What's up with the back of the Dump chamber? It's not like the T8, T8.1, or the T9. Is there a pressure relief screw there (between the two button headed screws)?

Tuning procedures for T8s involve:
  • Setting Velocity via regulator
  • Setting Relief valve until you hear hissing, then turning it back in 1/4turn. This will prevent hot shots.

I found this uv_halo post from Chachi's SA-8 thread helpful:

T8/T9 Bolt Push (Proper Gun Assembly)

Tiberius Arms Magazine (Standard T8 / T9 Magazine Maintenance)

Tiberius Arms Air Chamber
(T8 / T9 Air Chamber Maintenance- Advanced) Note the recommendation to use TechT Gun Sav to lube the bolt pin / fire chamber o-ring.

T8 Regulator (teardown and assembly)

T8 Breakdown (Breakdown and reassembly)

Tiberius Arms Conversion (First Strike kit install)

Enjoy!

the practice rounds are filled with baby powder. you can smell it when they break.lol

the sa-8's were designed with out a releife valve so police officers could shoot them at rioters at 350+ fps.

What is that silver thing on the back of the gun?

The top photo I'm assuming is from an SA-8?

Yep. I assume it is a relief valve, but a non-adjustable one set rather high.

Won't prevent a velocity spike if you manage to get liquid CO2 past the regulator, but should be enough to prevent damage to the gun if some officer left it gassed up in the trunk of his squad car in the middle of July in Arizona.

Read..the...first...thread.

All of this material is covered in there in detail from people who have bought them and dissected them.

That IS a relief valve, it's just fixed and fixed at a high pressure. It's not compatible with the Tiberius 8/.1/9 valve.

Tiberius Arms will punch you in the face if you call them with tech questions/parts requests about the gun you got for half price.
