So, I'm giving 4 stars due to when I received the firearm, almost everything was loose on it. The handguard was loose and wasn't in the "correct" position in relation to the barrel nut. The castle nut was loose as well allowing the buffer tube to twist. It's like this thing was hastily put together. So, I tightened all those down then test fired. Well, after about 15 rounds, it all came loose again! So I retightened the castle nut even more and for the hand guard I had to put a picitinny mount on the section where the hand guard meets the main upper on the firearm. This has "locked" the hand guard in place, which defeats the take down feature of the firearm somewhat. I will now have to remove the mount to take it down, but it's still an option. I have now fired 150 round through it and I must say, it runs excellent! I love this firearm! The recoil is very soft, you really don't even need the pistol brace. I can just put my cheek against it, look through my mounted flip up sights I added to it, and squeeze the smooth trigger and let it work! I switched the charging handle to the left side (I'm a righty) and now mag changes are a smooth process. Plus it allows me to have a backwards "HK slap" in an MP5 sort of way. So, so satisfying! Yes, I'm weird LOL.

Would I buy again? Hell yeah! Worth every penny so far! I've got my flip up sights, and a weapon light with green laser attached to it. Currently looking for a good 2 point sling. I'm also considering buying JRCs rifle conversion kit. That way, I will have two firearms in one! I highly recommend getting yourself one of these. There are so many ways to customize this firearm. They also have many variations of rifles and pistols to choose from, all with high reviews. Thank you JRC!!
