Roudi's cqbr project

[drewroud]

So I have tried a lot of guns out, and to me all aeg's pretty much feel the same. I am building this cqbr as a primary, it is pretty much going to be my gun that I play with everywhere, cqb, outdoor, you name it. I love performance and to tinker with things, so it not going to be an average gun.

The base is a king arms m4 that I got a year ago. The gearbox shell cracked, and I decided to replace it, and then I got the notion of building it even more.

Here is what the stock gun looks like:
www.evike.com/product_info.php?products_id=35201

Here is what I already have:

Externals
King arms lower / upper
ACM Magpul stock
Aim top Shorty 10.5 barrel
CYMA KAC Ris
JG dmr grip (uber comfortable)
Rear flip up
Clone Holo 551
Pro & T peq box - flash light and laser
Fake "Bitch" grip

As for internals, it has various brands. It is currently shooting 325 fps at 26 rps with a buffer tube lipo.

Goals:
200-300 feet range
Consistent 350 fps
35 rps with 11.1
Short trigger pull
Hop up tracer unit

Currently I have a modify 6.03, and the range will be achieved with an r hop patch. As for the 35 rps, I will be installing 13:1 gears and other various parts. I plan on fitting an 11.1 and mosfet in the buffer. I also have a speed adjustable trigger that makes the trigger pull very short.

Externals to get:
Vortex 14mm flash hider
Cyma qd kac suppressor
Tango down grip
Replacement light for the peq box
(I will replace the light module in the peq itself)

Eventually, I might build a dual sector gear for 55 rps in this gun.

Now the cool thing about my guns is that I install hop up trace units - hutu's. There are two led's in the hop up unit powered by a small 7.4 battery in the ris. I also installed a switch so I can turn it off and on. Great for night games.



This thread will be updated as I get the parts to show the progression of the gun.

Yeah, I like it a lot, it is adjustable so the trigger pull is very short, I just need to find a weaker spring for the trigger, the original king arms is a bit stiff.

Is it the stock trigger? Or aftermarket.

I think you would be able to fit the LiPo and Mosfet a lot easier with a crane stock, that is just my personal opinion. But that sounds like a heck of a gun you have their.

[drewroud]

Yeah, I don't see the point of having many mediocre aeg's, so I plan on having one or two kick A$$.

55rps? That sounds absolutely terrifying.

[drewroud]

35-40 rps sounds good to me, but people have used dual sector gears to get up to 110 rps. The problem becomes feeding. 55 rps is a good speed for dsg's in terms of feeding. I have to modify my magazines to feed even at 30 rps though.

[MayhemXXXFrosty (AndrewMp5k)]

Just use Flash Magazines, they tend to keep up with feeding a lot better than traditional hi-caps.

[Roger Monk]

So how much has this cost you so far?

[drewroud]

I would say about 150 for all of the internals and externals so far, I got the gun as a gift last year.
