G&P GBB M4A1 family

Recommended Posts

Hey guys. I'll be receiving my G&P WOC M4 soon (hopefully :) ) I've already planned on getting a full Ra-Tech BCG for it ... do you guys suggest any other upgrades ? like precision barrels or hop up ?

Also GHK mags. perform well in the G&P correct ? as long as you make those minor adjustements.

What should I go for ? RA-Tech hop up and barrel ?

 

Yepp. That would be your best bet. RA-Tech sells a hop-up+prec barrel combo at a -sort of - reasonable price. Go for the longer barrel if you don't have such low fps limits in your country as in the UK..

Thanks for the advice guys.

Regarding the inner barrel, on an M4A1 should I go for the M (363mm) or S(250mm) length ? keeping in mind limits here are 1J (although I will have the RA-Tech NPAS)

 

Cheers.

1J ? Holy ######... That is worse than here. In this case I suggest you go for the shorter barrel (210mm) . It will still be way over your limit. Mine is shooting 400 fps on green gas when the NPAS is turned off :)

Shoots 280 on duster gas. But it does not like the duster because the RA-Tech BGC is steel not alu.

longer always = more accurate haha so go with the long one!! then just tune down ur fps!! Man that sucks about the limit...mines shooting right around 3.5j (semi auto for sniping only of course hehe)

Yep that's around 330FPS if I'm not mistaken. I will be shooting indeed with green gas, but I thought with the NPAS I would be able to turn it down to 1J even with the Medium sized barrel what do you think ? Would I risk loosing accuracy with the shorter one ?

well ya you lose accuracy for longggg stuff but with the great ra tech hop up that should more than make up for it!!

You won't lose accuracy. There is just much of a difference in the barrel length. If it was between 300mm or 500 mm then sure you'll have noticable grouping differences. What it makes all the diffrence in the GBBR world is the fps. Longer the barrel higher the fps you get.

new barrel, new hop-up, NPAS or complete new BGC. Oh, and if you want to have bigger re-coil (especially with the tuned down fps -> better re-coil) buy a summer buffer tube spring. Much stiffer. You'll love it, trust me.

I just got a used WOC. Love it to death already, but the receiver wobble is potentially worrying. Do they make receiver pins to solve this?

ouch! $26 shipped from Asia. Anyone have them in the US?

 

buy the G&P one thats what i have. Hopefully you can order something else to make the shipping worth it. The RA tech one is insanely expensive! Only thing to know about the G&P one though is that sometimes its hard to close the body properly without loosening it!

Searched the web but to no avail.

 

Anyone got any links for the Co2 mags to fit the G&P family. Anyone got any feedback on them from use?. Are they as heavy as the GBB mags?.

 

Thanks in advance.

Sorry, but I don't think there are any gas in mag CO2 mags for the WA family yet. Some people are trying to cram a CO2 powerlet into a modded GHK mag, others have run lines to external CO2 tanks.

tinydata said "WA Family". A g&p mag is an INO mag is an AGM mag is a WA mag. So when you ask about a co2 g&p mag it doesn't make any difference. The difference is whether the system you're going to be using it in will hold together with the pressures of co2.
