My question is, what parts are included in the ra-custom package, such as the one here: http://www.ratech.com.tw/store/produ...?id_product=83

I would like to make sure about this before ordering other parts I am going to order.

purple: npas valve
brown: npas adjustment tool
blue: Hop up adjustment wheel
yellow: Pieces of paper to increase hop up effect
green: hop up rubber, and a ring that hugs a spring next to the wheel
orange and red: Those are trigger assembly pieces. One's the knocker that
hits the magazine and the other one is a firing pin base.
Pink: I don't know what that is lol. Only cause it's not in my scar. I don't think.

Installing the original delta ring with the DD rail? That wouldn't fit...

I got mine from Huang also, he told me that you said it would fit... It didn't fit. It threaded in 1/2 way before you could feel a lot of friction.

I shook my head and uttered "Stupid Lanny" :D

I took a Dremel and grinded off 1/2 of the threads in the barrel nut and have been using it on my RS/WE upper ever since.

As for the oring between the out flange of the barrel, I'm using a 1mm thick steel oring off a G&P RIS. I seems like a good substitute for the rubber oring if you are still experiencing some play.

So I need to add more o-ring shim for the barrel to stop wobble? lol :(

Now considering all the loose part I need to order, plus some of them are not even listed on airsoftbuddy, maybe I should just order a complete brass tube + hop up assembly.

the pink part (the colour of the dot) is the rubber insert that is in the end of the brass tube chamber. It captures and forms a seal with the end of the nozzle.

When I refer to the "tip" of the nozzle, I'm referring to the first 5mm or so of it. The part that is red in the MS paint picture. Reduce the diameter for a good fit...not shorten it, hahaha.

Problem fixed for the barrel wobble.
Seems like Huangs DD MK18 barrel nut is big, or that the diamter of the WE M4 outer barrel is too short.
I made my own shim, with hot glue gun... LOL... It holds perfectly now.

Does the WE take a real buffer tube/receiver extension?

hahah Anything to make it work. I'm not going to spend $$ for a real DD kit with the nut to fix a little wobble.


Anyways, is the open bolt out for the M4? I didn't catch on yet.

Should be this month I believe.

Would be great if someone could put together a list of what real steel parts will drop in, or drop in with some mods.

A few sites have started this, but are heavily lacking.

yea that would help a lot. I saw some magpul real steel grips on eBay and was wondering if they fit on to my WE Scar.

I am having difficulty with my M4. I just replaced part #66 and my sear is causing me problems. Can someone post a pic of their trigger assembly while it is in the receiver please. I'm not sure if my sear is in the right position after I put in my selector.

Also the spring that is part of the sear where is the long part suppose to rest whilst is is in the gun?


Thanks

I've already started a partial list on excel, needs some organizing tho. I'll try to finish it by tomorrow.
