I've had this gun for a good while now, out of the box it felt and handled great! The spring, as mentioned, is VERY hard to pull back, i didn't care and it bruised my hand because of it, i know wear gloves. The polymer stock and foregrip are durable and strong and being it's not wood it makes the gun even lighter, making it much better to carry around. I havn't had many troubles with this gun, so far the only issues i've had are, the front half of the gun wobbles, where the foregrip meets the metal body and the magazine wobbles. That's the only issues i've had with this gun, besides those two issues, this is a fantastic gun. I would approve of anyone else buying this gun.
Built in spring guide
very strong spring
Satisfying clink when the metal collides after pulling the bolt back.(just my opinion)
Magazine fits well and loads well
Polymer stock and foregrip make it very light for such a long gun.
Front half wobbles a bit(can probably be fixed)
Magazine wobbles(can be easily fixed)
