The PTS Radian Model 1 Gas Blow Back Rifle is a truly innovative rifle in both form and function. Firstly, the proprietary M-LOK compatible rail smoothly blends with the uniquely designed proprietary billet style upper receiver thus making the entire upper receiver assembly ultra-rigid. Installed in the upper receiver is the Radian Raptor ambidextrous charging handle. The billet style Radian lower receiver features an integral enlarged trigger guard, a flared magwell, and the ambidextrous Talon safety selector. Additionally, the Radian receiver incorporates the revolutionary Radian Weapons patented A-DAC (Ambidextrous Dual Action Control) which allows right hand shooters to easily lock the bolt to the rear without taking their hand off the fire control. To hold the bolt back using the A-DAC, simply pull the Raptor charging handle to the rear, depress the right side magazine release button, and then release the charging handle. A paddle above the right side of the ambidextrous mag release allows the right hand shooter to release the bolt forward with their trigger finger thus saving precious fractions of a second in getting the gun back into action. Left hand shooters have the same control benefit of the ambidextrous mag release as well as an enlarged bolt release/bolt lock paddle.

Assembled with our proprietary design PTS Enhanced Polymer Grip, Enhanced Polymer BUIS, Enhanced Polymer Magazine, and Enhanced Polymer Stock Compact and based on the incredibly robust KSC/KWA GBBR system, the PTS Radian Model 1 represents the pinnacle of the gas blowback training gun.

"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.

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

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.
