I currently do not own a LM4, but I am planning on getting one (this upcoming friday, the magpul pts version) and i'd like to get all my upgrades early.  What im looking at is mainly a TBB (suggestions? i was thinking the KWA precision, or the RAT)  Also to add the evo II, but i need to keep my FPS to around 400-410~ with 0.2g bb's.  would this mean with a TBB I would need to change my flute valve as well to ensure the right fps (and shave it as needed?).

Hi,

I too am looking at upgrades aswell.

The upgrades I'm going to order are
1) RA-Tech Hop-Up Rubber for KSC / KWA M4 GBB Series ( 2012 Version )
2) RA-Tech Complete Hop-Up & Inner Barrel Set for KWA M4 GBB
3) Magazines, since they are uber hard to find!

I would suggest an NPAS system for a fully adjustable FPS, this way you can adjust it +/-. When I called into KWAUSA they recommended a flute valve, but the flute valve is a set number, I think on a regular LM4 I read it's anywhere from 280-350 FPS (CQB) (Facts might not be accurate)

Still figuring out what else to get too, haha.

Before you start shaving or cutting anything you should chrono your LM4, both before and after installing upgrades. Also, you might want to hold off on the upgrades, at least during the warranty period. Get to know the rifle, that way you will know how the upgrades affect it. Either barrel should suffice, both are of good quality. You may see a boost to your FPS afterwards, and from there you'll be able to determine whether or not you need to shave the flute valve or cut the valve spring to raise or lower your FPS respectively. I tried the NPAS and I found it less reliable than my stock bolt. Honestly I'd rather have two OEM bolts. They're easy enough to switch out.

I sadly dont really get a warranty... or at least it appears that way.... i live in canada... unless im mistaken.


**edit**
i also work a pretty good job, and dont mind spending extra money to get LOTS of spare parts to experiment with. (I actually intend to have as many spare parts as possible, as a CYA, because, you never know)

Hmm this is a good question, wonder if us Canadians get warranty..

Canadian Retailer -> Consumer (us).

I ordered the part's I mentioned Earlier.

Boobie Recommends the "KSC Diamond Hop Up/ Maple Leaf" I'll pick that up sometime later..


I plan on running stock for a bit once I get more magazines, I want to get used to the gun before I slam upgrades.

Get the EVO II and Maple Leaf bucking, best upgrade you can buy in my opinion. At this point I've messed around with the internals and externals a little but all in all what it really needs now is a tight bore barrel. I think I may go with the RAT, though I'm very open to other options as well.
