I'm going to do my best to keep this from being really long.
This gun shot great for a week, then my first day at Fightertown, first shot I tried to chrono, all I got was a little poof of air. I got that fixed and no longer have an issue with it.
I have two or three issue I want to get parts for pronto before the weekend.
I kept getting jams where when it wouldn't fire and I pulled the bolt back, two bbs were stuck on and above the feed ramp. I read this is because the hop up can move a bit and the best fix is to cut a groove into the in effect barrel forward of the hop up unit And out an o ring there to hold it.
The next issue is that it's not very accurate and in full auto they go all over the place. I used to hit guys that were running from cover to cover with one or two single shots from my TM M4 AEG. I have to spray a wall of bbs for them to run into with this. I read that the hop up bucking and hop up suck and that a Ra Tech (which as I understand is the same as Maple Leaf, is this correct?) Evo II hop up up unit and bucking will make things so much better.
I found this, and want to get it because it will solve all these problems:
http://www.evike.com/products/41049/It is a Ra Tech 6.01mm inner barrel and Ra Tech complete hop up unit and bucking. The barrel is already notched and comes with a c clip that fits the notch and holds the hop up in place. I'm sure it works way better than a notch cut by hand with a dremel and an o ring. I have some questions about it though. Please look at the link.
First - I was told by an Evike Customer Service Rep (not a tech agent though) that 6.01mm barrels are only usable with semi auto fire, no full auto firing. Ra Tech makes and sells it for this KWA gas powered LM4 though. Will I have any problems with it in my KWA shooting full auto? I understand that quality bbs are a must.
Second - every time I read that that hop up was a must and improves accuracy a ton, it was always called a "Maple Leaf Evo II". The above link where I want to buy it does not call it a Maple Leaf, but Ra Tech. It's the same right? And I don't know what degree the bucking it comes with is, but what is the difference? What's a 75 degree going to do vs an 80 degree or a stock degree bucking?
Please help me out here guys. I need to order ASAP. I'd like to hear what everybody who has an opinion has to say, but please let me know (us actually, this could help others in the future too) if you're just speculating, are restating what you've read online, or are an experienced airsoft techie or have first hand experience with KWA GBBRs and the type of parts and issues I'm talking about.
Thank you guys so much for your help. I sure do hope I get my original username back (see my introduction in that part of the forum) but either way I'm glad to be back on here. It seems like it doesn't get as much use now that airsoft isn't totally new like it used to be but that is okay. This forum is a wealth of knowledge from good guys helping other good guys with the sport we all love.
Thanks again,
Joey N.
