-Possibly new reg (I found the hose placement weird and uncomfortable)
-barrel kit (though the stock one is decent)
-new grips (I found the stock ones fat and uncomfortable)
-new trigger (I find the FBM wave trigger to be the best around)
-new feedneck (twist-clamp feednecks suck)
Giant trigger guard
System X is out of business
Idiots who claim it's a cheap knock-off
The System X NME LE is a custom Intimidator-style marker from a company that is no longer in business. Is it the fault of the product? If I am using the NME LE as a baseline judge, then definitely not.
The NME LE is a sick marker capable of mowing faces and surprising the competition. Why? Because everyone seems to have a stick up their a$$ that this thing sucks. That it's a cheap-o Timmy knock-off and will never perform well.
Those same people are the ones who've gotten wasted by a "lame gat."
Much like the famous Intimidator, the NME is fast as hell and rarely breaks paint because of the excellent eye system. In fact, I have never chopped with this marker - even with the eyes off (though that rarely ever happened). And while it also has all the complicated internals of a Timmy, it's fairly easy to clean, lube, and maintain. I've never had a problem with it in the first place (even after playing in sand, dirt, rain, and mud) and cleaning it out was always a very simple operation.
There is also very little kick (the only other marker I've used with less has been a well-loved Shocker) and the gun remains quite efficient and consistent after break in (we're talking +/-2 on the stock reg). And to the whiners who complain that it's too heavy - work out and get rid of your stick-arms! This thing is very well balanced, even for the anemic, and its length makes it quite comfortable once you put a tank on it.
The WAS board allows for very easy programming and contains all the modes you'd ever need (PSP, NPPL, etc...). The multicolor LED on the handle is bright and easy to read and also a breeze to push (some of these other markers have had buttons so impossible to operate, I wondered if they were originally designed for children).
Also, the giant trigger guard allows monkey-handed folks (like myself) to rip without looking like a goofball.
My problems are few with the NME, but they should be addressed:
1) The trigger sucks, IMO. It's smooth and moves very nicely, but I hate the shape of it. FBM makes delrin after-market triggers on the cheap (both wave and blade style) and they rock. They truly allow your fingers the fly.
2) The stock grip is like a cheap Dye Sticky that's fat and thick. I got some nice Hybrid ones and the problem was solved.
3) The stock reg works well, but it has an odd hose-placement that made it awkward to hold. Replaced with a CP reg and, again, problem was solved.
That's really about it. Otherwise, this is one of the nicest markers I've used. Any doubters were silenced when they had a chance to use my NME. It's a quality product and you will not be disappointed with it.
Of course, now that System X is out of business, finding parts and getting repairs done will be a bit of a hassle. However, parts kits are on ebay all the time - usually going for $50 (o-rings and bolt) to $100 (bolt, solenoid, new WAS board). Since it's also (basically) a smaller, lighter Timmy, anyone familiar with them should be able to translate that knowledge over without too much difficulty.
A few places are making aftermarket parts for the NME as well since its users tend to remain die-hard fans. Alamo City Paintball has just started making a new bolt and FBM makes delrin triggers (as stated above).
There isn't too much else you'd need to do, honestly. The feedneck is Impulse-threaded (only for the LE version) and it takes cocker-threaded barrels so what else do you need?
I have recently bid farewell to this lovely marker, but it's given me no grief and no problems the entire time I've used it. If I didn't have so much crap already (and bills to pay), I would have most definitely kept it. That being said, I would buy this again in a heartbeat if I had the spare cash (esp. now that they go for under $400). For that price? It cannot be beat.
I give it an 8 because: a) I never give out 10s and b) I deducted one point for the difficult-to-find hardware
