Vfc Mp5 GBB

[jsmithski]

To keep this thread alive I’ve made my own DIY redneck NPAS inspired by this video:

it works perfectly, I was able to get down from 1.55J to 1.15J.

Here’s something I’ve built just today.

There’s a lot of misinformation and false claims calling these bad ass replicas “the worst gbb ever created”. Especially now when they released v2, I think it’s time to give it another shot. Here’s my story...

I’ve bought vfc mp5a2 gbb in 2017 and haven’t use much mostly because I only had one mag and it had feeding issues. After some time looking at it hanging on the wall (and because I had few other gbbrs to play with) I’ve decided to make it skirmishable, that’s when I’ve come across nugentgl videos on y2b (long gone unfortunately). The issues vfc decided to skip during their QC (as usually) were easy to fix with aftermarket upgrade parts - this is the core of bad publicity, most of the reviews were made when those were not yet available on the market. I’m a gbb freak so I’ve bought almost all available upgrade parts... ended up with double the price of the gun itself plus I’ve added 4 mags to the set (worth noting the v2 mags fit v1 mp5 and even perform better than v1 mags). The ultimate skirmish ready vfc mp5 gbb part and mod list:

1. enhanced feeding ramp (crusader iirc) - fixes feeding and mag wobbling issues 

2. Hop up vsr mod - makes it shoot laser straight and greatly improves seal. I use maple leaf autobot bucking, omega nub and crazy jet barrel.

3. That’s all. Seriously no more. You can still put in all additional upgrades but they will not do much good. Steel firing pin makes sense. And removing ejector lever that keeps scratching the bolt. Let me know if you got one, I’m curious if you had same issues.

What hop did you use for you to add the omega nub? I have the a3 and having hella problems! Lol my crusader feed ramp shattered after upgrading to a v2 bolt setup. And the hop unit is just garbage

@jsmithski

When I search or the Hop up VSR mod I get a ton of stuff. Can you please share a link or a description?

Thank you!

I just installed the V2 upgrade kit and now I want to putt more good things into my MP5. Anyone having experience with the T.N.T. hop up chambers?

Also I found out about a WA M4 hop up unit from 5KU that can be fitted for the VFC 416 and VFC Mp5 gbbrs - anyone having experience of that?

 

[Twinadad]

Hmmm. Do you have the V1 or V2 SD?

Hi I have the V2 and want to convert it to HPA WHATS YOUR THOUGHTS ON THIS? Been looking everywhere and to my surprise no joy. I thought this would have been done already. Maybe I’ll be the first ?

 

[emilianoksa]

The V2 may well be a good gun.

But VFC has poor parts support.

 

[Twinadad]

What made you want to give it up? If you don’t mind me asking

Yes, I upgraded an A2, including with the T-N.T. APS-X System T-HOP - that one's gonna increase the fps, if you need that to happen.

Here's the list of mods on it:

-          T-N.T. APS-X System T-HOP (220mm) [87 USD]

-          Crusader Enhanced Feeding Ramp [7  GBP]

-          Angry Gun 120% Recoil Spring Guide [11 GBP]

-          Crusader Steel Hammer [22 USD]

-          Guarder MP5 Tactical Handguard [59 GBP]

---------- Surefire 6P ORIGINAL [60 USD]

---------- Cree Led Forend light [25 GBP]

-          Low Profile Scope mount [13 GBP]

-          Navy Flash Hider [45 EUR]

-          Bow Master CNC Ai Magazine Follower [10 USD]

-          Various magazine valves tried and tested (not sure which one was chosen in the end)

I also upgraded the bolt carrier sets (I tried several configs) with a shiny Bolt Cover Assembly. It's always nice on its own, and it's cool to see the bolt lock in place on the side when the mag runs empty, because of the mag followers installed (and those were actually quite difficult to install; I broke the seal of 2 mags doing that, and couldn't repair them).

The carriers I've got:

1)      Standard carrier and nozzle

2)      Crusader Steel Bolt Carrier with Enhanced Cylinder Set [60 GBP] and Ready Fighter Reinforced Loading Nozzle [12 USD]

3)      Standard carrier with restricted gas exit hole nozzle (for lower fps / different gas like CO2 - via a special mag) [X]

4)      Zinc bolt carrier [25 GBP] with transparent reinforced loading nozzle [15 USD]

In the pics the other one is an A3, also from VFC - sadly :wacko: this all has to go as I'm leaving the UK. . and I've placed ads in the classifields.

Guess I'll live with these pics afterwards!

Is it V1 or V2? 
im assuming V1 if you’re struggling. It’s way too fiddly, but you can do it with a normal Allen key, but it’s still a nause. 

 

[Patooo]

Help! Patience is disappearing with v2 bolt/nozzle assembly. I am installing a low power set up and I can’t figure out how to reassemble the bolt/nozzle without messing up the nozzle spring. I have destroyed 2 so far! Are there any videos on assembly/disassembly of the bolt/nozzle? Thanks!! ?

 

[Bada Bing]

I used a valve key to remove the base cap of the bolt carrier at the rear. From there I use my finger to push the back of the nozzle forward, making sure the nozzle spring is indexing the nub on its base. Then I carefully guide the front part of the nozzle back into place. Extremely fiddly but as long as the spring stays straight and in place, you can allow the front of the nozzle to back down into the carrier and click onto the rear section. 
 

I haven’t seen any videos on this. Once you have it attached you can test it by pulling it forward and letting it spring back.

Help me please! 

So I got the VFC MP5A3 and everything was fine until I noticed that the bolt open system that the mp5 has is fucked up.. 

After the last BB shot the nozzle slaps against the follower which caused the problem that one day I was shooting the bolt didn't hold open anymore after the last shot fired. The nozzle and followers were damaged so much that the nozzle passed threw it now. 

So far so good. I dremeld the followers a bit more open so the nozzle could pass them at all time and since the real steal nozzle has no bolt open it was fine to me. 

Probleme here was that the last BB didn't feed well because it wasn't hold tight enough in the follower. 

And I also had feeding problems that my BBs sometimes didn't get fed well into the hop up chamber and got smashed around it.. 

Well that sucked. 

So I ordered a CNC aluminum nozzle from bowmaster with the cnc aluminum followers.. Sad story is that I still have the problem. The BBs doesn't feed well into the hop up even with the new nozzle and get smashed around it.. 

Can someone help me on this? 

Maybe you have another solution? 

I also have a new original plastic nozzle at home but need to get plastic followers for it, since plastic nozzle on aluminum followers doesn't sound good at all. 

I wanted this to be my winter project but it fucks me up so much since the mp5 costs 620€in Germany and I want it to work.. I mean it's summer :/
