RA TECH AGM M4 GBB upgrade with RA TECH parts

[S13mASSImo]

For me the npas bolt didn't fit into the carrier correctly, so now my bb,'s just get jammer in my barrel or just roll out. I had to modify my carrier to get the retaining clip back on, so now i have a gun that doesn't shoot and lost 100 euro's...

[TheBlabla1996]

at 5. 40 it sounds more like an m60

[SwarmAirsoftuk]

is the AGM model fully compatable with western arms and ra-tech parts?

[ajsy1031]

@SwarmAirsoftuk yes it is since it is a WA replica.

[TheKmk4420]

was that a glass dish it was punching holes throw i want it were can i bay this upgrade let me know thanks

[AirsoftBackUp]

what did you upgrade in the gun its self? and does the upgrades steady the rof

[Peter421]

Wow. this makes it able for anyone to pass a chrono test and then have them turn it back to shoot extremely hot. That hurts.

[NJtriple6]

do you guys still sell the AGM GBB? and do you take all major credit cards? visa, MC, Discover, Amex? if so, how can i contact you?

[ratech5915]

@NJtriple6 still got a few pcs, try search RA-TECH online, and you would be able to get our contact info.

[xSogAirsoft]

hello, I have a GBB SCAR, can you list all the upgrades for ANY gbbr? I dont know any..Thanks for your time! xSog

[ratech5915]

@xSogAirsoft not quite sure about your question, does that mean list all the upgrades we know for gbbr?

[xSogAirsoft]

@ratech5915 yes, Like all upgrades reccomended for GBBR's, thanks, for your time!

[Omen4500]

People tell me this gun leaks really bad. Do you have upgrades that can help that?

[jauniirs]

What material is the npas made of? 

[Casper48022]

this shit is ridiculous... what is the point of making airsoft guns with a visibly similar bolt barrier/internal parts?... ..

[epiphonel100]

you wouldnt happen to have a website would you i would be happy to buy this gun if you did.

[ratech5915]

@epiphonel100 yes, we do have a website

[pj0998]

can someone please tell me what the part that is seperated by the spring the side that takes the gas in and is closest to the barrel. i dont know if this is a gas gun but i got a gas kjw m4 and i broke the place were the gas gos into the gun and i need to order that part please someone

[MrMatomi]

This M4 is Custom work Gas series (section of your site) ???

[NooberPwner]

What was that piece u put in and what does it do? I'm gettin an agm m4 so I think I'm gunna get some ratech stuff in there

[CristianBeltramo]

The black part (RA Tech) he replaced for the white plastic one is the Bolt.

I'm getting one of these too, and you can read everywhere about the agm bolt breaking after a few matches of use. However, as you can see here (and another video in youtube I can't remember) there *is* a loss in FPS after the switch.

The NPAS (nozzle thingie you have to install to adjust the FPS to your desire) is also a must.

[p3la0]

do you sell ratech , do you ship world wide?

[ratech5915]

yes ,please contack us

[richardmak92]

is this the NPAS set?

[nmacomber]

yeah..... pretty cool that this is an airsoft gun and not a real m4. maybe he should put airsoft in the description...

[samjaymz19]

thought this gun got 450 fps standard

[eleeschalow]

With the NPAS you can adjust the fps from 200 to 450+

[SpecialOpsM4]

can you please tell me what he changed with the bolt? im getting an AGM M4 GBB and i would like to use these parts because they obviously seem to work but i was kind of unsure as to what he actually did

[CaerBannog1]

He added an RA Tech bolt with an RA Tech NPAS valve which gives full velocity adjustment from 300fps to 500+fps with the twis of an allen key

[CenturyChild1102]

Hey what did he/you change about the gun? what is ra tech now? and what other upgrades can i use????

[CaerBannog1]

You can get uprated bolts, bolt carriers, NPAS valves as well as uprated charging handles, steel bolt catches and steel sears which are all much higher quality than the cast aloy original parts.

[CaerBannog1]

Oh and I forgot to add metal hop chamber and uprated hop rubber

[batanidoc73]

it can even do 500fps on green gas,dnt wori bout the gas, it works! it wont damage the bolt head that much unless u use strong recoil spring. change the hammer wth bearings. works well.

[nathanael117]

if i got an agm m4 gbb and bort this RA part would i be able to adjust the fps to like 350-370? also would this decrees the gas usage and or increase the rate of fire?

[batanidoc73]

yeah, it uses negative press. concept per bernaulis theory, velocity nd pres. r inversely proportional, its rmarkble that its adjustble thru the bleed valve ports. thumbs up!

[goldeneye007662]

All of this works with WA, G&P, AGM, and JG GBB's./

[InfuriatedKIDD]

wait hold on.. i got kinda lost....when he was changing the bolt can anyone tell me cleary what he just did that increased the fps like crazy?

and do these modifications work on the JG gbb?

[rhyreza]

this ra tech naps will fit in m4 jg gbb?

[goldeneye007662]

Yes, it will.

[peashooter101]

Thats really cool but I'm just wondering if the extra gas will damage the barrel over time like some other gas guns.

[LordByron08]

Where can you buy this?

[SHUNT311]

Will this stop it from blowing up after 100 rds?

[goldeneye007662]

Yeah. RA-Tech is a GOD with GBBR's

[Vietboy1st]

if you look at 5:15 . i have that bolt carrier in my AGM. I love it.

[driftinsti]

Does your Ra-tech complete NPAS bolt work with the AGM m4?

[ThePurcy]

yes theres a video on it

[driftinsti]

thats just the bolt nozzle. i'm talking about the carrier+bolt(aka complete bolt set.)

[Vietboy1st]

Yes it does. I bought mine a mine and it works perfect.

[CRC1770]

Hi Guys,

Can you give me a list of parts that you think I will need when i get this gun ?

Thanks.

[driftinsti]

-new complete bolt

-new hop up chamber

-new hammer

-anti rotation links

-new recoil

-new charging handle

-new aluminum buffer

-possibly a new buffer tube

[Importdrifter]

unless you get a new metal body no other buffer tubes will work with the stock AGM M4 body.

[Vietboy1st]

yes i can

[ApolloISO]

i was thinking about getting the AGM ris gbb M4, but i dont want to buy if if its a P.O.S lol. does anyone have one that they can vouch for? i spent almost 500 for my G&G and fielded it 2 times before it broke and i dont want to go thru something like that again

[XxBuzzkill77xX]

i actually own one, honestly i was skeptical too, but when i actually got the extra money and balls to buy one, i couldn't have been more pleased, it is an extremely reliable gun and i personally would prefer it over an AEG, the only thing that you really need to worry about is the hop up unit which is plastic. it breaks on 90% the guns, i would get a WA hop up chamber right off the bat and replace it, and with RA-techs bolt assembly you really can't go wrong, this gun has not let me down yet!

[warpix]

I can vouch for it, I just brought it out for a game yesterday.

But you will need a new bolt catch and bolt carrier. I put in a G&P bolt catch and a RA Tech NPAS bolt set. Not to mention that the stock bolt fires a little hot at 430 fps. You MAY want a metal hop up chamber and some anti-rotational links.

One note though, firing full auto on the AGM mag makes it inconsistent, and it leaks. You'll probably want non AGM mags.

Single fire is fantastic though.

[threebud]

Were can i buy the ra tech bolt and the G&p bolt cacth?

[Vietboy1st]

i know where.

[jchoo34]

if youre willing to spend $200 on upgrades for this it shouldnt give you a tough time.

[multisync36]

How come when it fires in full auto, theres no cool down like some of the other AGM m4s i've seen?

[XxBuzzkill77xX]

Oh trust me, there's definitely a cool down, maybe the RA tech bolt reduces that, but honestly the cool down isn't all that bad on full auto, you can get a couple of dead mags where if you fill up on a cooled mag you only get a few shots out of it, but for the most part its a wonderful weapon.

[warpix]

There was a little near the end of his full auto tests. The RA Tech bolt seems to be better at full auto than the stock AGM one, but it still can't consistently fire a full mag on full auto.

[Oxstayne]

the RA TECH bolt carrier weighs more thanthe stock 1 lol

[alteclansig]

i see your using green gas why doesnt your mag explode and isnt the stock agm bolt not strong enough for green gas

[Oxstayne]

its strong enough the WA M4 isnt

[cockofdoody4ftw]

second gen agm m4 tough enough stock... 420 up fps green gas right out of the box. magazine leaked a bit with green gas but the new mags dont. soon as they came i grabbed 2

[XxBuzzkill77xX]

green gas is the same as propane, just with added lubricant, the stock mag *SHOULD* be strong enough to hold green gas, but if your going to buy mags, spend ~$10 more and get the WA ones, they are much better than AGM

[jchoo34]

$10 more! WA is like $95 to $105!!!

Get the GHK or the Bomber mags... about $50...

better than WA by far.

[driftinsti]

Do all the parts you have for the WA m4 fit with the AGM m4 such as the hopup, barrel etc.?

[UBCSWraith]

most do. It's supposed to be 100% compatible, its really more like 90-95% compatible. Very few parts like the bolt catch are not compatible. But barrels, hop-up units and rubbers, bolts, hammers, triggers, magazines, ect. all fit.

[Oxstayne]

the agm mag weighs more cause it a gen 2 mag so it doesnt leak

[x1bx]

I'm a new guy in the airsoft area but I see in the video like a different bolt carrier and a different metal nozzle, is it right?

Or am I wrong?

And in the site of RA Tech I don't find anything in the list for AGM but a spring and a Tool Ajust NPAS Set. Don't know if that includes other parts than the only tool to ajust FPS/Pression.

Can anybody help me with this?

[KaKaShiHatAkeSenpai]

AGM and WA are compatible.

So you have to search for WA parts...

[jaabueg]

In the end of the video, they show a different bolt carrier (silver with Vltor markings), which bolt is that?

[Chan1254]

where can you get those parts?

[xxthehuskycaboosexx]

can you put this and the npas 2gether

[TALIZAIN]

please, can you put a list with the RA TECH parts that you put in the gun? and please put where i can buy this parts, thank you!!!

[UBCSWraith]

I dont know about RA-Tech parts, but the main weakpoints on the AGM are the bolt head, magazine, and hop-up unit. The bolt is okay, but will eventually need replacing. I plan on a full RA-Tech NPAS bolt and a G&P hop-up unit, unless RA-Tech's is better somehow :p

[kullwarrior]

MINIMUM parts requires:

*Hopup Unit

*Bolt Stop

*Buffer Tube

*AND DO your homwork

[Vietboy1st]

do you know where i can get the hop up ?

[kullwarrior]

ratech, redwolf, honest can't you just google it?

[Vietboy1st]

do you have aim so i can ask u more stuff about it. i am not sure what to get or need for my agm m4.

[kullwarrior]

just pm me and Ill give you a forum where you can find all your homework!

[hawkeyes39]

I REALLY want to buy this. Where can I get it?

[ratech5915]

pls visit our webset.

[sammarshall25]

Hi could you tell me what the name/model number of the part is that I will need to decrease the FPS to 350? Also how much variance is there in the FPS (i.e. if I don't want it any higher than 350 would it be better to go for a standard FPS of around 320/330). Also how long would you estimate the original internal parts will be good for before requiring replacement? Really good video as well - Thanks :)

[hawkeyes39]

If you want low FPS, use duster instead of GG/propane and adjust the FPS to the lowest setting.

[AzonaDbacks12]

can you make a video on how to disassemble the bolt carrier

[mrezzy]

RATECH, I see that you were using Green Gas, doesn't it leak in the mag?

[ratech5915]

leaking ,i think sooner or later will be happen. whatever any kinds gas.

[rambo4532]

I think you can use the G&P reinforced O-ring sets which were designed for the WA mags, not sure though, but that would help!

[hkseo100]

Hey guys.

Will you be making a replacement metal bolt for the AGM 062? (Bolt, not the bolt carrier)

Also, will you be making a metal spring buffer for the AGM?

[mrgeo1024]

Holy ****...:-) That's amazing... So it needs Your Ra-tech bolt carrier or just nozzel with NPAS?

[ratech5915]

just only nozzel with  NPAS

[tomss2005]

I want to put RA complete bot carrier with NPAS in my AGM will it fit?

[goldeneye007662]

Yes, you can

[Irsifar]

Screwby...

[pmac1985]

can you adjust the fps down, with the same part you added.

the limit here is 350fps.

also is it possible with this gun to cut the part on the fire selector like on the WE to make it semi only

[Stickyittoyou]

HOLY CRAP! That is awesome! I can't believe how much of a change there is in the FPS, that is a great system you guys got going there. Just like a valve for a faucet. :) Genius!

[AzonaDbacks12]

can you use an inokatsu bolt with this thing

[ratech5915]

need to cut about 4.5mm on button of boltcarrier.

[AzonaDbacks12]

nice thanks for maybe taking my advice

[Maekiii]

So is the agm gbb m4 a clone of a WA?

[ratech5915]

yes

even the manu

[xyx661230]

hoiiiiii
