subscribe to help me find the 16mm carrier

I want one!

Had the money for a VT but I bought a PSG-1 instead. Back to square one and save my pennies again.

Thank you.  A very objective and the start of an interesting series of informative vids on ViperTech. I've recently bought what is considered by some as a good gbbr by an alternate manufacturer (within my budget), but would own a VT if money allowed. Saw a vid earlier today by someone not impressed by their VT purchase, and all he did was whine about how bad things were. Don't judge on one persons view. Do your research, and if you're ready to commit, enjoy your purchase, and make it work...

Details, good video quality.. you deserve more viewers.

great way of doing a review, thanks for telling us the stuff we want to know

Big big fan of VT too, pretty sure you gonna adapt more and more Vipers like I do.

In love this video!
Great job!
Do they take real trigger?

Thanks for this video, you just earned a new subscriber :-)

very nice video sir all said is true i got 5 vipertech  since 2012 and you will never go wrong in choosing this master piece

I confirm. Mine is 11 years old. This machine is indestructible and probably as solid as a real one, and yet I do not spare it: only for target shooting, it is optimized and modified for the most power and blowback as possible with CO2 (580 FPS, 0,25, 20°C ). I have never broken anything on it! Out of the box, the bolt catch has been slightly modified (a few file strokes) to work 100% with GHK magazines and the spring replaced because it was too flexible. 1 bolt carrier and its nozzle (not broken but worn inside and making the seal very perfectible) have been replaced after several years. A few hop-up rubber and o'ring replaced during maintenance. That's all !
On the other hand I also confirm not to use the 18 mm bolt with CO2 : the walls at the entrance of the nozzle move apart and the bolt ends up blocking in the upper.
Enjoy !

I think the rumors of them being "collector guns" and "not field usable" comes from people who have used Inokatsu M4's before VT adopted the design. Inokatsu had similar manufacturing processes but bad QC imo. I have an inokatsu from 2012 just before VT took over and using it out of the box was frustrating at best. It takes alot of work and modification to be taken to the field reliably even to this day. I hope I can be able to get a VT someday so I can finally see how far they have come since inokatsu. On the bright side, I learned alot about GBBR modding on WA platforms.

Awesome work bud, really thankful about this. I am considering a Vipertech because I only use GBB but there isn't much info like this online, mostly only durability/ drop tests and stuff...I want to know if the realism factor is worth the money, for me I'm trying to simulate a real combat situation as close as possible for training purposes. The Viper Tech factory is in Taiwan and I live here so I've been considering a trip down there to find out more but it's quite far so long story short, thanks for this.

great video and finaly in 2021 form. Btw vfc Bolt carriers with theyre npas work to if you change the chamber and hop up unit for a GHK one. i did this because all my local fields had diffrent fps rules and it worked great and consistant. :)

thanks your video。recently i want to buy  viper gun

Sadly, viper tech not allowed to ship these to America now because they put restrictions the lower receivers being imported into the US.

check your nozzle if new model there may have screw thread inside output hole,,  drill a grub screw insert to it can adjust FPS.

First of all, like most other Hibernators, the Viper Tech M4 sleeps in winter.

I wanna know how to mod ghk stanag mags. Cant wait

question 7? what do you say me about the range and precision

AAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
