Agm m4 gbbr

Some of the information on this thread is from third party sources while other is from personal research.

I will add more to this thread as i find new things (still a LOT of parts coming in to try).

AATV Youtube Review:
YouTube - AATV Video Review: AGM M4 Gas Blowback

GasGuns.Info Review:
http://www.gasguns.info/?p=164

Known Problems:
Weak nozzle. Breaks after a couple hundred rounds.
Magazines (1st Gen) usually leak gas.
Weak hop up unit. Breaks after a couple hundred rounds.
Bolt catch is fiddly (some work, other don't work, especially 1st gen).
~400fps out of box, not gamable in most Canadian fields.

Solutions:
Multiple companies offer aftermarket parts for the AGM to make it a more reliable platform to game. Every month we see new companies/parts poping out on the market. Sources say the Chinese cloners are currently working on parts for a cheaper solution than Ra-Tech or G&P.

http://en.ratech.com.tw http://www.gp-web.com/en/index.php

Bolt Carriers:
The first thing to look at is the bolt carrier. Ra-Tech offers different solutions to make the AGM more gamable. Any of the options bellow will let you adjust the FPS of your AGM to make it gamable.

Options:

#1
RAG-AGM--001 (NPAS Tool Set) $60USD


#2
RAG-WA-bolt014 (Complete bolt solution, silver) $260USD


#3
RAG-WA-bolt-015 (Complete bolt solution, dim grey) $260USD


G&P has just came out with a NPAS style bolt carrier. It has not been tested AFAIK.

RedWolfCustoms also make a 'light' bolt carrier ($105-$115USD). Be warned it needs to be sanded/dremeled to work properly (toward the end of the bolt, its oblivious if you shoot it a couple times). Because of that, i do not recommend it as a drop in.

RWC Silver Bolt Carrier:
http://www.redwolfairsoft.com/redwol...l?prodID=25954
RWC Matte Silver Bolt Carrier:
http://www.redwolfairsoft.com/redwol...l?prodID=25629
RWC Black Bolt Carrier:
http://www.redwolfairsoft.com/redwol...l?prodID=25628

You will need a nozzle:
Pro-Arms Hi-Power Loading Nozzle



Hop Up/Tightbore:
The hop up is very weak, if a double feed occurs it will usually break the hop up or the nozle. G&P, Prime and Pro-Arms have you covered.

Options:

#1 G&P WA Hop Up + Tightbore (Any 1 of those) $67USD
http://www.redwolfairsoft.com/redwol...l?prodID=26120
http://www.redwolfairsoft.com/redwol...l?prodID=26119
http://www.redwolfairsoft.com/redwol...l?prodID=26118
http://www.redwolfairsoft.com/redwol...l?prodID=26117

#2 Prime Hop Up (You will need a tightbore) $74USD
Hop Up that takes any AEG tightbore
http://www.redwolfairsoft.com/redwol...l?prodID=25781
Hope Up that takes WA tightbore
http://www.redwolfairsoft.com/redwol...l?prodID=25780

#3
Pro-Arms Adjustable Hop Unit
+Guarder Hard Type Hop Bucking
+KM 6.04mm TN barrel for M4


Buffer + Buffer Spring
The AGM buffer/buffer spring is weak and isn't as smooth as it should. G&P and Ra-Tech have made drop in replacement.

G&P offers a couple different kits that are drop in and offer different recoil strength. Any of those fit drop in and work much better (even under water!).

G&P Silver Buffer + Buffer Spring (HHR) 'heavy recoil' $16USD
http://shop.ehobbyasia.com/upgrade-p...m4-series.html
G&P Black Buffer + Buffer Spring 'normal recoil $16USD
http://shop.ehobbyasia.com/upgrade-p...m4-series.html

Ra-Tech has their own WA style buffer/buffer spring, its a drop in:
#1
RAG-WA-stock-001 'Summer' $10USD

#2
RAG-WA-stock-002 'Winter' $10USD


MORE TO COME:
*Magazines
*Lower (G&P Anti-Rotation Links, G&P Steel Bolt Catch)
*RAS/RIS Compability
*Dimensions (flash hider threading, stock tube, threading sizes/direction, etc)

I accidentally sheared-off the fixed screw in the stock. I don't think I was being too abusive when I retracted it, but nonetheless it happened. A $2.00 part, no big deal.

Just besure to note that the products made usually are meant for WA/WOC not AGM, some parts is not a direct drop in. Eg Stock tube, there's the WA/WOC/Prime/Firearms and there's the AGM unique, same with reciever there's couple of factions: WA & WOC, Prime, Inokatsu, AGM, King Arms. Not sure if Classic Army are unique or not.

Besides, it makes me wonder why people are still getting a AGM when JG has a better option with less problems. But for me I'd still vouch for a WOC (Recommand CQBR due to barrel length is all the same)as it gives 380 fps. If you want a more durable one, get Prime which means you have to build it ground up. And probably in the end for a really really abusivable you're gonna have to replace everything except the internal moving parts with firearms stuff.

JG copied WA and left a plastic body. Same problems as WA. With the AGM you already have a full metal base gun.

Theirs not much to do... get a AGM, buy a Pro-Arms nozzle and a Ra-Tech NPAS tool set, total is like $100 shipped to you and your AGM is fully gamable. If you want to spend a bit more, buy a G&P hop up + tightbore and your completely set for $500-$600 less than a WE, half the price than a Inokatsu.

But to each their own, its all about how much you want to spend. AGM just shows you do NOT need to spend +$1000 to get a gamable full metal GBBR.

True, I did a calc of DIY and build a G&P from scratch if I recall correct it goes to about $1200

I'm building a G&P/Prime myself to compare to a modified AGM.

For a M16A4 you would need to find a 20'' Front Kit, G&P makes a nice one, and a full stock. The stock may prove problematic as I'm told the AGM lowers have proprietary threading on the buffer tube, meaning most aftermarket tubes will not mount to the lower, preventing you from using current stock options.
