WE Gas Blow Back M4A1 Carbine

Recommended Posts

Now, the biggest improvement I made today was with the buffer. I dont know if anyone else has tried this yet but I figured I would post it up here anyhow. My friend has a rifle style buffer from a real AR-15 and, for those who dont know, they contain weights in them like all real steel AR-15 buffers. So today we decided to take apart his and mine and it turns out the stock WE buffer is hollow inside like the real gun allowing for actual weights for real steel guns to be installed. The stock buffer weighs 25 grams and after weighing it with 3 buffer weights and pads installed it came in at 80 grams! Thats 3.2 times the total weight of a stock WE buffer. Needless to say this increases the kick substantially while only minimally affecting the rate of fire. I am quite pleased with this modification and so far there dont seem to be any issues with it. One thing I did note about it, however is that in the 80-100 shots I tried with it, the harder kick actually managed to work the buffer detent screw out and began contacting the bolt carrier as it traveled rearward into the buffer tube! A few minutes later and some blue loctite and everything was running great again. I'll work on getting some pics together if anyone would like them since, like I said, I'm not sure if anyone has done this yet. I'll also be sure to get any updates if I begin seeing any ill effects on the gun from this (which I doubt since there really isnt any additional wear on any parts and no physical dimensions were altered).

 

Good idea man :D

Please keep us updated on how this works out and if it results in any problems? It sounds great though!

You mentioned over at GGI that it results in recoil on par with a real AR-15 :o I'd love to try this mod out.

Yeah, when we tried it out it was having roughly the same kick as a real one. The gun now visibly jars backwards towards the user. It always did before but as an observer its much more evident now. Using it with the eotech, the gun actually jumped enough the at sometimes the reticle would disappear from the line of sight momentarily. Good stuff :). Now where it differs is in the "snappi-ness" of the recoil. Locking the bolt back and releasing it really shows how the bolt has slowed a bit from the extra weight. It sounds slow in that instance but when you fire the rof doesnt really seem too affected. Sounds like the real guns ROF now which is cool.

well, used mine for the first time today in a skirmish.

 

I managed to hit bugger all really compared to my usual standard (the hop is still wild and I don't have a decent selection of ammo to try, limited to 0.2's and 0.36's at the mo).... BUT..

 

I had an absolute hoot. I don't know what it is, but this thing is just a blast to use.

 

Its a real shocker getting used to 30rnd real caps, certainly makes you think about your shots and keep a count of your ammo. Blowback is just excellent. Really enjoyed using it.

 

Now all I need to do is make it shoot straight and I'll be a happy man.

 

New barrel/hop and CO2 mags me thinks...

Good to know it's a fun skirmish-able rifle. So has it been confirmed that there is going to be a gen3 m4 with the new hop up?

WETTI are releasing an inner barrel with a redesigned hop, in around two weeks i heard :-)

So then the recoil weights don't really have much use in your average civvy semi-auto?

 

About how much weight would make sense to add? Think I might stick a handful of lead fishing weights inside the recoil guide along with a small piece of cloth to prevent them from rattling.

 

 

Edit: Also I think I can agree that the Krytox grease is as good as it can get. Seems to be made of angel's tears or something, just wish it wasn't priced as so...

I noticed on many WE M4 there's a gap between the upper and lower receiver, easily visible if held against a backlight. Is this also apparent on a real M4?

Also, the nozzle is putting marks on my bbs resulting in knuckleball flights . Is WE going to resolve this issue? Any DIY solutions yet to this?

If you check out the TS One website, they have the add-on weights (says how heavy) for sale plus a 90% recoil spring. They also have a replacement buffer thats already made heavier and according to them adds 75% to felt recoil.

Some real ones have them. You can shim it by adding material (i used a thin layer of super glue) on the upper receiver pin holes.

As for damaging the bbs upon chambering, you can smoothen out the inner and outer edges of the nozzle tip with a scouring pad/steel wool, just enough to round the edges.

So, this is my M4 as it looks today.

Still to come are a Ergo grip, Magpul trigger guard and a CTR stock.

 

This is the ebaybanned $40 D'Boys RIS btw and it does indeed wooble without modifications.

Roughly about 1mm to left and right.

I applied some scotch tape to the groove on the inside of the top part of the RIS which sits on the barrel nut and now it's solid as a rock.

 

But for some reason my bolt catch doesn't work properly. Well, acutally it does when I push down the bolt catch with my finger, but the pin or the spring inside the magazine seems to be too weak to fully engage the bolt catch lever.

Anybody else having this problem?

Would it work to shorten the Boltcatch spring?

 

btw, does anybody know a fair source for a Magpul trigger guard without excessive shipping costs?

The gap doesn't disappear no matter how hard i press the upper down. Besides, adding material in the pin hole will only make knocking the pin in and out harder, increasing takedown time.

Full Gear Up are resonable on shipping cost and can supply all of the above at good prices.

You can get RS pistolgrips at any firearm onlinestore.

 

And I also think the AEG gris won't fit on the WE because the holes for the screws are in different positions.

You probably want to make sure you get the RS Magpul Trigger Guard rather than the PTS one. The PTS one is wider and may not fit in the WE.

So what would be the best way to increase the recoil? The Recoil weights and the 90% recoil spring? Or the replacement buffer? What about both?

Not sure what this means???

 

Are you talking about the dallops and smudges of black grease it applies to your bb's while loading? Which all GBB do?

 

If so, lighten up the use of silicone in your gas mixture. Canned green gas is out (in my opinion) its all ###### out there today (100% AIRSOFT SHOOTING SILICONE WITH A BIT OF GREEN GAS ADDED!!)

 

And keep the breech clean. And inner barrel while you are at it.

 

If your chopping bb's, that has EVERYTHING to do with the brand of bb. It not your WE's fault.

 

Try a different brand. And dont use "bio degradeable bb's" - I know some say they use it just fine, but I dont use bb's made of dog food - especially in a gun that is over 500fps.

 

Last thing - perhaps a weakly powered mag is the source of yours (or anybody's) chopped bb's (not clearing the bb stack on the back stroke -misfeeds=chopped bb's).

 

The sharp edges in the forward breech have ZERO to do with chopped bb's and misfeeds. That isnt an issue at all.

Somegirls, I have the same Dboys RIS...when you say wobble, are you talking about rotation wobble? Can you be more elaborate on how you fixed it? The top half was a very tight fight (bottome section fit just fine) especialy around the toothy barrel nut...but I can't figure out which part is causing the wobble...super annoying!
