Hello there 
I have a lvl 50 AR/Traps which is quite pimped out with IOs (Viper Force).
Off the top of my head build is as follows :-
Burst 4 slots
Beanbag 5 slots
Flamethrower 6 slots
Ignite 5 slots
Full Auto 6 slots
Webnade 2 slots
Caltrops 1 slot
Triage Beacon 6 slots
Acid Mortar 6 slots
FF Generator 5 slots
Poison Trap 3 slots
Seeker Drones 5 slots
Trip Mine 6 slots
Also Snipe 5 slotted
My pool powers are Flight,Speed,Fitness and Teleport consisting of hover,fly,hasten,superspeed,hurdle,health,stamina and recall friend.
Now obviously this build is slotted for maximum gain from recipe sets,etc and also IO procs like build up,etc.
So I would suggest starting off by taking burst,slug and buckshot to get u through the early lvls then respeccing em out later.Leave the grenade and time bomb alone as well,grenade causes too much aggro and time bomb is the suckiest power around.
Make sure to take 2 fitness power before lvl 18 so u can get flamethrower as soon as its available,also webnade + ignite kills bosses very very fast,well any mob really
Feel free to skip beacon and go the aid other/aid self route although I never solo so beacon helps all team members at once
Poison gas IS as good as ppl make out and acid mortar makes a nice lil personal tank as well as debuffing anything with a pulse,mine has +20%to hold,10% chance to heal 5% hp and 5% chance of build up IOs slotted in it.
It has held the AV tree in the respec TF as well 
You may feel a lil underpowered in the early stages of AR/Traps but stick with it and u will experience one of THE most fun builds I have ever played in CoX
This is our lil secret k
ps seekers are awesome for taking alpha strike as well
pps I also have the +stealth run IO slotted so that I am invisible when I run in to drop poison gas,etc.
This may not be an option for you for a long time unless u got a high lvl char to feed u inf or u get lucky and get the recipe as a drop (might be TF only).
Hey there, got a AR blaster and a Merc / Trap MM so, put both of them together :} and here it is

Obviously, this is a build without IOs. And I wasn't sure if you wanted the PPP Pet or not, but just shoved it in there anyway If you decide not to choose it, I suggest sniper rifle instead. Have fun!
So after browsing the uk and american boards, I couldn't put my finger on any of the builds they had for an Assult Rifle / Traps corrupter, so I'm going to ask all you kind people if you could help me out here?
PvE btw, can't see myself doing much serious PvP outside of RP fights.
See i want my build to have as many powers from Assult rifle and traps as possible, pools kept a minimum. This by no means has to be a maxed out build, but of course it needs to have some going power.
Of course I could just take the powers at each level, but because I suck so much at slotting, that wouldn't be very good for me.
So, any builds like this would be greatly appreciated
Oh, and mace mastery epic if possible.
