This gun is a good deal for just $45. It is a double action semi-automatic gas non-blowback side arm. The extension piece that makes it look like a Robocop gun can be taken off, only if you do, you can see the exposed barrel at the end. No, the barrel does not stick out, it is just visible and flush with the front end of the gun. The weight is good, although it comes from two weights located at the front end of the barrel, and it gives it a good counter balance to the all-metal magazine. When firing this gun without the hammer cocked back, it has a fairly tough trigger pull and can cause inaccurate aim. If shooting with the hammer cocked, the trigger pull is much easier and of course causes the shots to be more accurate. The gun shoots VERY high at 50+ feet. After 50 feet it tends to do an escalator ride straight up with the occasional dead on shot, but 50 feet and under, it is extremely accurate. The hop-up, located on the top-middle part of the slide and seems to be absolutely useless. Not matter where I set it, the BBs tend to fly the same patterns. Magazine is well constructed. Holds somewhere between 15-20 BBs. I don't have a speed loader so gravity doesn't stack the BBs very well. Also, the magazine is just a little bit loose inside the hand grip, but it really isn't that bad; it stays in there good. The magazine release in located on the bottom near the hand grip, kinda weird but it works good. I am having one problem, but it may not be with the gun, it may be with the Madbull Propane Adapter. When loading the magazine with propane, the seal leaks profusely and spray propane everywhere, but it still loads the mag. Like I said, it is probably with the adapter. Propane release valve works excellent. Shoots about 4 to 5 full mags on one charge of 5 to 6 seconds.
Easy to Use
Very Accurate in CQB Situations
Removable Front End
Excellent Amount of Gas Storage
Mediocre Amount of Rounds (20ish)
Sounds Really Good
Hop-Up is useless (But you really don't need it under 50 feet.)
Hard trigger pull whilst not cocked
Magazine a LITTLE loose.
Barrel is not a tight bore, prolly around 6.06-6.08 (Estimate only, I honestly have no idea! The reason I say this is because when I clean my G36K, the cleaning rod is tight in the barrel as I twist, but in this gun, very loose, like a lot lizard. [my g36k has a 6.03 diameter])
Overall, this gun is a great deal, everyone should purchase this for a sidearm or a beginner gas gun.
