Tokyo Marui Colt Licensed Mk18 Mod.1 MWS ZET System Gas Blowback Rifle w/ Cerakote Firearm Finish

"Took this to a Milsim event and performed exceptionally well out of the box all weekend long. Firearm finish is fantastic the rifle feels very solid and holds up very well. Added a few attachments to personalize it but other than that it was completely out of the box new. The bolt was even lubed well enough I didn’t have to apply any more. Fired around 500 rounds throughout the weekend and Accuracy was great with every shot. I had high expectations for this rifle especially with this price tag and Tokyo Marui definitely delivered. I am very happy with this weapon and would recommend it to anyone interested in a MK18 GBBR

"Was able to snag one of these from overseas last November and play a couple games with it. It's the exact same thing as the standard MWS that's been sold before, which means amazing performance out of the box. Only difference is you're paying for a nice DD Mk18 rail. I've run it completely stock on propane, with the only internal upgrade being a new hop-up nub. I've been told to grab an spare nozzle spring, as that's one of the few things to fail when running on propane/green gas, but mine hasn't gotten to that point yet. When I play indoors I switch to duster gas, because on propane I was hitting about 330. For those worried about low FPS, you could always put a longer inner barrel. All MWS come stock with the the same length inner barrel.

If you plan on keeping the original Mk18 rails and not changing anything internally, I highly recommend it. If you want to change out the rails and upgrade internals (in the upper receiver), I'd say save your money and get one of the cheaper variants. TM used a proprietary method of attaching the Daniel Defense rail, so it doesn't install like a regular DD rail. There's an additional barrel nut locking the rail to the barrel, which fastened by loctite. You'd need clamp it down, apply a ton of heat with a heatgun and get special tool to get the barrel nut off. I recommend the TACTICOOL22 M&P 15-22 BARREL NUT WRENCH. There may also be threadlock on the screws holding the gas block in place. After playing with a very temperamental upgraded WE M4 gbbr for almost a decade, the TM ran circles around it out the box. If you got the money to spend, go for it.

Pros:
-Great accuracy and range out of the box
-Extremely reliable. Can full auto no-problem, but if you're playing with a GBBR, you shouldn't be full autoing anyway
-ZET system guarantees bolt lock when magazine is empty
-Can run on propane/green gas and duster
-Excellent gas efficiency

Cons:
-Mags are expensive and go out of stock often
-Mags are low-capacity (35). This is a positive for me, coming from 30 round mags
-Rails are very difficult to remove and require special tools
-Expensive
