The M4A1
It started off as a stock TM M4A1 but a few paychecks later it got
SAMURAI S.I.R System
SunProjet M203 RS
G&P ZM Flash Hider
Box of M16 star mags
It's shooting about 380fps on a fresh battery.
I spent ruffly about $1800 on it so far.
Only problem with it is I found a small hair line crack in the mech box 2 month ago. I'm living and working in Tofino for the summer so it'll get fixed once I get back home. It'll also be getting a paintjob :cheers:
I'm also using a glock19 with a metal slide as my side arm here's a photo but who dosnt own a glock yet. I payed $200 for it brand new.
Now the MP5K
This was a fun gun to put together plus I got it for my gf who loves playing and is now a member of CIA on Vancouver Island.
It started out as a normal MP5K
A stock MP5K is vary weak and only shoots about 240fps... it's a great CQB gun but not so good when playing with a bunch of people with upgraded guns.
So this is what it got
G3 inner barrel
EG1000
9.6v bat
PDW stock (where the battery is hidden)
New spring and bushings
And a silencer to hide the inner barrel
(
I also got the TMC RIS Foregrip but dont have a photo of it with it on... I'll get one by the end of this week hopfully)
The MP5K is shooting about 360fps on a fresh battery.. only problem is it dosnt like semi auto at all.
Added this photo showing the inner barrel apon request.
got the gf to send me some photos 
It cost around $1200 to get the MP5K together but if I bought a MP5K PDW it could of been a little cheaper.
That's about all.
