Beta Project AK and CYMA M14 Socom Upgrade help

[Mausturm]

Hey all,

My name is Tristan and I'm an airsofter hailing from BC. I'm currently working on two project rifles (three if you include the already sturdy VFC SCAR-L I own. Though it shoots well, so I won't do anything yet to it), one is the Beta Project AK which I intend to make my main (once I get it shooting correctly that is) and the other is my DMR project, the CYMA M14 SOCOM. And I need your assistance because I have run into a few problems with both rifles.

First, my Beta Project problems.

Now I have run into a few problems already with my Beta Project AK. The first problem is the hop-up unit itself, which to me seems to be hit and miss all around. The hop-up slide that lets me adjust the range of the gun is loose to say the least and is prone to self adjustment when I fire in bursts of 3-5 rounds per trigger pull (even Semi-auto, and I do have a fast trigger finger). And, when using 25's, 28's--and to a degree, .30's, the shots tend to be all over the place, hitting everything around the target, and sometimes, by sheer dumb luck, the target itself.

Now, I've put in a new guarder bucking, an Element H-hop and a Guarder inner barrel, but haven't yielded any better results. If anything, it just got worse as now I have to, quote on quote, warm up the gun before it starts shooting even remotely well with .30's (it under hops the first few shots, then after a warm-up, shoots correctly). I've done some diagnostic work, and the hop-up right now that I have may be a damaged unit (considering the play in the slide that makes it hard to be precise when adjusting my hop) so I may be in the market for a new hop-up chamber, and if push comes to shove (this is a project rifle) a new gearbox.

Right now, what I have in the rifle is as follows...

Stock Mechbox (CYMA brand I believe)
Stock High-toque Motor (CYMA Blue bell)
Guarder Inner Barrel
Prommy Purple bucking
Element H-nub
And stock Hop-up chamber (CYMA)

So, to round this all up, my question is, what should help me gain some more accuracy out of my Beta Project? With the stock settings, with thirties, I can hit targets at 200 feet, though no where near as accurately as I would like with such a heavy BB. I'm trying to avoid having to go over 400 feet if necessary. Though if I am forced into the position, I'll jump on the grenade then. Right now, I've been looking at different hop-up units and (if shoved) at gearboxes. King Arms Hop-up Chambers, Pro-win and Echo1 MAX CNC are on the short list currently (AK hop-up). Any builds I should be looking into for accuracy in particular? Any other hop-up units, etc..

As for the M14 SOCOM, that is another project DMR rifle (shooting 400-410 roughly at the end of this) and really, the only question I have is what would help achieve accuracy and range from this thing? The one I bought didn't seem to perform nearly as advertised with 28's (doubt 30's would help if it couldn't hop 25's or 28's). Got only 100 feet out before it died.

Should I change the hop bucking/chamber, the barrel? I do know I will be replacing the motor, but what else should I look at? Any help would suffice.

TL;DR. What parts would help me increase the accuracy and range of a CYMA AK, and M14?

Sincerely,

Tristan Wong
