"This thing cranks! Yes, fire rate is a lil slow but it is accurate and great for cqb. Build quality is great. I purchased the 6" version and it does not disappoint.

"Build quality is really good no wobble at all you are limited in battery space but not too bad, everything feels really good shoots far for a cqb gun would not recommend this for long ranges but medium to short , i got the 4.25" LITE HANDGUARD / 350 FPS) , overall only thing i am going To change on this is the motor its kind of slow

"so i was looking for a smaller rifle for outdoors for 2 main reasons, easier to maneuver in the brush with, and lighter weight, but still full metal. this went on sale and I picked up the 4.25" model in 2 tone gray. it is not a bad rifle by any stretch, but it severely lacks in some key areas, all are easily fixable. first on foremost was the color, I actually regretted purchasing the 2 tone gray color, the pictures are not very telling of how light the gray is, its almost a primer color, I painted mine black to match everything else, if you plan on picking one of these up, I would recommend sticking with black or dark earth. second major complaint is the motor is atrociously bad, easily the worst airsoft motor I have ever encountered, reminds me of the old G&G motors before G&G got good. absolutely pathetic ROF and sounded horrid. I was getting 14 RPS on a fully charged 11.1 30c lipo. super easy fix and swapped it on the spot for a better motor. accuracy and range was what I was expecting, not good, I almost felt the 4.25" model was to short, but with a vertical grip and emg guardian suppressor (short) handles amazing, i put in an extended inner barrel and new hop up, its usable now, but im not thrilled, will require more tuning to get the accuracy and range I want. internally its held up fine, sounds "strong" and "clean" after swapping the motor. my last biggest complaint is that the stock is super loose, loosiest stock I have ever felt on any gun period, its bad, it rattles, this was remedied with electrical tape. surprisingly I like the stock, I usually swap that out right away, stick with buffer tube lipos or tri cell lipos on this, the stock is shorter than normal and gives me the perfect length of pull maxed out ( i usually run m4s 2 or 3 clicks out).
I am so impressed with this rifle that I plan on picking up different lengths when they go on sale in the future, take my advice if this rifle catches your eye, wait for it to go on sale and pick one up, just be prepared to swap the aforementioned parts on the sport, but it is an amazing gun with tons of potential
