"Hands down best gun I have ever had!! I have had a lot of airsoft guns in my lifetime but this gun is one of the best it has great fire rate and never jams. I would recommend this gun to an intermediate player because it is not a toy and has to be handled by the right person.

"Great and reliable AEG. I've had this thing for about three years and it's still working like it was out of the box. All the other reviews have probably gone into detail the pros and cons of this weapon, but to put it simply, you won't go wrong choosing this weapon.

"So i am now going onto my 3rd year using this same exact rifle weekly. I run a 11.1 on her and still shoots like an angel. I switched the barrel for a 14.5 inch, and still has the range that no one else has. With .25 and a 11.1 im still getting 340 fps. Theres many pros and plenty of cons but cons you wont notice unless working on externals of the rilfe. Pros are, she still shoots amazingly 3 years later. You could throw a 10x's zoom scope and a bipod on it as a dmr and still out range 90% of the snipers out there. Very hard punch behind it too. Very nice receivers. It does have your average plastic pistol grip and crane stock but trust me on this. This is the best crane stock you will own, i got rid of mine for a krytac and i regret it so luckily i found a friend with one and im trading for it. The stock did have a little wobble but just take it off and throw velcro under it on the buffer tube. No barrel wobble or anything. The 2 piece barrel is also a wonderful thing to have,rails are beautiful but that it where the cons come into play. This gun is near impossible to replace external. The rails have one of those delta rings that spin not the spring ones. I ended up having to saw it off to get the delta ring off to put a 12 inch daniel defense rail on. It will fit your gun. You have to hammer it on tho. You have to get the delta ring off in order to get to the barrel also i do believe i dont exactly remember. The stock is also a big pain to get off because the fuse is in the stock but is screwed down. So you have to unscrew it and throw electrical tape around it and throw it in you stock. The gun over all is the best gun i have used you cant go wrong with kwa, but when it comes to easy customization it gets a 1 star the gun id give 100 stars if i could.
