"I think this is the best budget Ak you can buy in the market. The Hal mosfet feels like a simple version of a Perun mosfet. The trigger response is exceptional and when paired with the precocking feature, it can make it very snappy. You can use after market gears on this with no problems. It does not need a magnet on the sector gear. The exterior construction is well built and the quality of the polymer is comparable to G&g. For the price point you can’t beat it. It has decent accuracy at 300 fps with the m90, but if u change to a ported cylinder you can achieve 340 fps with a m90. Its has about a 300mm barrel on the 105 version. My only gripe about the gun is very critical, the spring guide on this gun is not secured with a screw cap or anything. If you switch springs with an after market one, the spring guide will get miss aligned and will jam the gearbox. So stick to only Specna springs because it is short and will fit perfectly in the gearbox. I stripped my original gears doing this. Good thing I was gonna upgrade it anyways. Overall if you just leave this gun alone ,it would of been just fine. This is still a better option than most ak’s in this price range. Love it!

"First off I’m gonna say the flash hider is the worst part of the replica on the 74 model. The flash hider itself is glued and the adapted is also glued that reveals the 14mm- threads. I tried hot water but I ended up having to dremal it off. Cant torque on the flash hider to much as it’ll damage the front sight post. But not necessarily needed to do, I just have 14mm - everything.

Secondly this gun is way more than I was expecting for 150. Shoots amazing. Very responsive. Well worth the price, they could charge more to be fair. Def a sleeper ak, seemed cheap but premium performance. Nice to have a gun you don’t need to upgrade out of the box as it already is for you. I’ve never tried the brand until now but I’m gonna be looking into more of their products lol.

"Great shooting and looks are nice, mix of polymer and metal, metal dust cover. Only thing is how to remove the orange tip, seems to be the hardest part. Great build quality and the HAL mosfet is amazing. Takes 11.1 Titan stick batteries with ease.
