    Initial impressions of the VFC/Umarex HK417 AEG

    Well, that's not what they replied to my e-mail a few months ago. It seems that they plan to release a 16" and 20" versions around the end of the year. There has been some infos around from other sources that seems to go the same way. It's not clear if it will be complete replicas only, or upgrade kits, or both.

    KJW KC-02 GBB Tactical Rifle

    Some news today. I received an answer to an e-mail I wrote to ra-tech a few days ago. According to this answer, this npas http://www.ratech.com.tw/store/product.php?id_product=188 is a drop in into the KC02. No modification required. I'll try to verify this information if I order some parts in a shop that carries this part.

    Okay, after comparing the KC02 valve and the NPAS, many things were different. Although, there were only 1 diameter that would need some change to make it at least feat, if not work. So, this morning, I had it machined on a lathe (is that the correct way to say it?). It was a bit risky because it didn't leave much matter on the NPAS and would weaken it, but it survived. And this afternoon, I fitted it in place of the stock valve. Firing test... Okay Adjusting test... It can adjust the output power. It's probably not the definitive product as I may tweak/test some more but for the time being it seems to range from 280 to 430fps roughly. May be subject to variation when I'm finished fiddling with it.

    For the power, not great... Noticeable variations. Just like you'd expect from a gbb. For the precision, didn't have the opportunity to shoot in decent conditions. A lot of wind these days, and didn't shoot at targets. Just to test the hop-up. I will test shoot at targets from various distances eventually, just don't know when exactly.

    For the time being, I'm mostly a bit under 400fps using ultrair. I cut a bit of the hop-up rubber lips and now I can adjust from 0.20 to 0.30 max. That's about what I'm looking for. Maybe cut a bit too much if I want to use heavier bbs later but I plan to use bio 0.28 or 0.30.

    Some tweaking/upgrading today. I put in an homemade tuffer buffer like in gisburn20's tutorial. Exchanged the inner barrel and hop-up rubber for ra-tech ones. I still have way too much hop-up. If I unscrew completely the adjustment nob, it's just right for 0.28... If I screw it enough to get the first "clic", it satellises all weights I have up to 0.36 at least, probably more. That's definitly weird.

    Err... Can't edit my previous post? Weird forum... Anyway, I also got a npas which I will try to fit in. And on the long mag, the gasket seems to be "eaten" by nozzle, which doesn't happen on the short mag I have. Edit: found how to edit :° Didn't find how to suppress a post.

    I have long read your topic gisburn20. Already gathered the parts to make some "tuffer buffer", maybe with a slight modification. Got my ra-tech inner barrel and hop-up as well. I may start installing all that at the end of this week. On another note, I have some trouble with my stock hop-up. After some cleaning and a few shots, it isn't greased anymore... And it makes fly all bbs I throw at it up to 0.36, set to zero. I'll try to have a look at it and guess why when I disassemble to put the ra-tech parts in.

    Hey there. Just received my KC02 V2. It doesn't come with a cleaning/unjaming rod. But there's something on the components list included with the exploded view... It does list the component of a CO² magazine.
