"Gun does have to be “ broken “ in but honestly even though it doesn’t have a mosfet this thing is pretty good for the price, now I have an lm4 as well, which to me is a better metal, my only minor complaint is the trigger guard in the pictures here did not come with my gun, mine has one that kinda looks like a “ g28 “ trigger guard, I tried taking it off to swap it with the lm4 and some how cracked the metal. I glued it back on so well that you wouldn’t notice it but ..... I DO..... other than that. I’ve got an 11.1 strapped to this thing and I was literally sniping people with it. Got an r.I.s rail system on it, mag pul rail covers, and a 4x zoom acog lol

My first game with it I hid up in a building and hit 15 people and I wasn’t touched once, had my tracer unit on as well, which does make the gun a little hard to use in cqb but screw it we have other people to take tight corners I’ll provide over watch lol fine with me.

Don’t think about it, if you find one of these just get it. Right now this and my krytac alpine white vector are my favorite guns, and keep it between us...... I was liking my m4 better that last game. But please don’t tell the vector I swore she was the one for so long ......

"I got this package today and right away I started to use it, the gun feels super nice, does not feel like it will break. Real sterdy full metal with some obvious strong polymer to lighten the load. The relievers are full metal which gives it an amazing feel. It is real comfortable to hold and feels it will last for a long time. The gun is accurate and precise, I took it out side and set up a small target and was able to hit it a good 30 ft away. 100% recommend this gun!

"For the price point you really cannot do any better; trust me I’ve tried (been playing airsoft for almost 20 years and have owned over 30 rifles). Bit since the other hundreds of reviews online have told you this is a great gun for the price, here are my thoughts on the features I like/dislike.

Chrono’d at an average of 350 FPS with .25’s after I put about 1000 rounds through it. Currently shooting 24 rps with a 15c 11.1 LiPo. FPS is very consistent shot to shot (less then 5 FPS \-) which is indicative of a nice air seal. Accuracy and range are excellent stock based on my experience (I’ve seen others gripe about the hop up on KWA’s but that was not the case for me). Hitting an Evike popper target at 50 yards with acceptable consistency. Variable FPS is an awesome feature to fine tune performance without having to change springs. I also love the cut off mag feature since I hate dry firing (basically telling the other team I am about to reload so please rush me). Fit and finish is on par with every other high end gun I’ve owned. Eligible for Evike’s bonus program so you can pick up a spare mag or other goodies for free also.

My only gripes are the wiring in the buffer tube is too long and too thick (think desk lamp sized power cord rolled up inside a buffer tube). Not a big deal if you have the tri-cell style lipo’s; also a small 11.1 LiPo will fit vertically in the stock end cap. Other concern is the durability of the cutoff mag. I haven’t attempted to use them in any type of fast pace game where rapid reloading is needed, but I’m concerned the bb follower protruding from the mag will break off if rattling around in my dump pouch or if the mag is tactifliped to the ground during an engagement. Neither of these are even close to deal breakers; more info for you to consider.

All in all it’s a great rifle and you won’t be disappointed
