"Bought a 9month used model no upgrades. Disassembled, cleaned & lubed. Still shooting perfectly. Shoots much faster than it seems/feels and more quiet than my other gbb due to its long barrel. I threw an Acetech Lighter R and a triple combo acog 4x32 onto it. All the mags online were sold out so I bought a similar mag that’s a typical metal AR mag, then filed the top ridges off and now I have two perfectly working mags. I do a ton of modding , tech, and own upgrades so the mag deal wasn’t an issue for me.
No cons with the rifle imo.

"Really great gun!
I get can get through 2 mags in one fill, but the second mag putters out fast and sometimes doesnt fire all bbs or lock back before out of gas.
Shoots straight, great hop up design(rotary and tooless, no bucking). Shoots hot at about 1.77j (~435fps with 0.2g) on a 73 degree F cloudy day, so you will have to get the cqb style bolt carrier, or jet nozzle if you can find it in stock anywhere. Got the heavy recoil upgrade sold here on evike, makes it snappy and everyone on the field will know it's you shooting and will probably reference how cool it sounds. Hops 0.28g bbs quite consistently if you always top your mag off with green gas when reloading. Once it's been neutered by the cqb bolt to make it field legal at most places, it will probably be shooting 380 fps w/0.2g, so it might not be strong/fast enough for .28g to get good range and not be "dodgeable".
Its a gbb so you're probably buying it for the cool factor and fun reloads. You will be out classed by any AEG that has an upgraded hop and if the shooter can aim at distance, but within 30-40yrds it wont make any difference. The LM4 mags look and work great in it. Ambi controls work great and love the bolt lock on the right side mag release. Wish the spring in the charging handle lock (part that locks it to the reciever) was stronger. I find myself partially racking the bolt when it rubs on my kit or recieces any sort of force, which makes me think I'll end up with a double feed and jam. Never jammed or double fed yet from normal use. Got about 500 rounds through it so far, only time will tell, but for 450 it's a real treat.
Great GBB with some well build internals, doesnt seem to have much pot metal within, so I dont really see a reason to upgrade those parts if there even exists upgrade parts for a kwa.
Glad I made the switch from AEGs. Even though it cant compete with aeg technology of this age, it makes every "kill" that much more satisfying.

"Brand new to airsoft and all the YouTube videos and forums advise against going with a GBB due to cost and “maintenance”. I went with this platform because I have to have my B5 pistol grips and actual B5 SOPMOD stock to mimic my real AR. The trigger is okay..pins do tend to walk a little so watch out for that. Handguard is nice and in spec. I’ve got a BCM Foregrip, Magpul sling mount, and a Streamlight Protac HL-X on an Arisaka scout mount and they all stay secure. Orange tip was a PIA to remove, but now I’ve got an SRC tracer unit on. If you didn’t already know, don’t use a crush washer with any type of tracer/suppressor. You will get a huge Point of Impact shift. At 45 feet I was able to get 3” groups with a HoloSun 510C and no magnification.
The recoil impulse is nice but it’s very different than a real 5.56 impulse..more clunky and delayed. Sight this rifle in properly and adjust the hop up and you’ll be good to go. Turn the hop up right to increase, and left to decrease. Replace the iron sights with Magpul MBUIS if you want quick deploy sights. I got plenty of kills playing with this rifle and only 1 mag - you will have to be ammo conscious and pick your shots. Use sound shooting fundamentals and violence of action and you won’t need more than 2 BBs per nerd. I have only had failure to feed issues when the gas was depleted in the mag. The bolt sometimes doesn’t lock back after the last BB has been shot..you might shoot a few bursts of air before you realize it’s empty. No big deal on all of the above. It goes “boom” when you’ve got a full mag like it’s supposed to. Overall 4.8/5 stars for me.

"Alright so ill break this down
The gun is fantastic, external quality is flawless. Not a single scratch or dent on the gun, no defects. It feels really nice and shows no sign of "cheapness".
To address the KWA hop up concerns, this gun seems to shoot as straight as my Krytac SPR which is a pretty accurate rifle.
Pros:
Flawless externals
THE BEST ambi lower on the market. The controls work so smoothly and are easy to reach for leftys and rightys
The included magpul grip is nice but im gonna swap it for a BCM
The included stock is really comfortable
The magpul iron(plastic) sights are the best iron sights ive ever used. I would not mind using them on the field instead of an optic
No ugly airsoft trademarks anywhere on the gun
Good kick
The barrel has ZERO wobble. Most high end guns have even slight flex to them, this one DOES NOT WIGGLE
Overall length is good. Its long (not a SBR) but shorter than a krytac SPR. A perfect length for outdoors, I would even be comfortable indoors with it
The gun is lighter than an aeg until the mag is in it
Cons:
No sling hook on buffer/receiver out of the box
I took a warm mag outside which was filled with valken green gas, could only get maybe 20 shots before it was EMPTY. It was cold outside but the mag was warm from being inside. Ill test it again in summer months. However the mags are supposed to be great so my guess is the weather was the problem for me.
Mags are very expensive
Its another m4, but the best one ive ever used in terms of external features and set up
Internally the KWA system is great
Its $450, you get your moneys worth but after spending $50 per mag.... Its an expensive gun to own
Hop up is somewhat time consuming to get to, be careful adjusting it
It doesn't come in Radians beautiful bronze color that the real gun can come with

"Super glad I bought this one instead of other lm4 such as Emg SAI gray. I mean gray is a good gun but in comparison to this radian model 1 it’s a no game. Anyone who looking for hige level GBBR m4 style rifle this is the one to go. Hope they make a Combat one!

"This is a pretty good and fun gun.
The fit and finish is excellent. Rail and receivers are tight together and don't wobble. PTS mags fit flawlessly, firm with 0 wiggle but not so firm that it impedes movement. Bolt is crisp and has a nice kick.
The ambidextrous fire control, bolt release, and mag release are nice features. The ambidextrous mag release stood out to me as particularly good. Unlike other ambi. mag releases the left side is easy to hit and the travel distance is nice and short.
However, I have two gripes with this product.
1. The gun can jam pretty bad on a double feed. Two or more BB's can get stuck in the chamber and get lodged in.
2. The barrel nut is extremely tight. My hop up on one rifle got messed up and I can't even attempt repair because of this. I contacted PTS/KWA and it appears that the barrel nut was installed way too tight and KWA had to use a table vise with a heatgun to get it off. Hopefully this gets corrected in future production as I am sure many people will want to upgrade the barrel/hop up.
