Amazing rifle 10/10

This rifle can be upgraded and cranked up from 400fps to 550fps with upgrades, could also just increase the speed with a new M130 to a M160 spring . I also highly recommend to not using 2.0g as those are for CQB and just spend the extra money getting 3.5g - 4.0g for increased accuracy for long distance shots. A bipod and scope is most definitely recommended for better results of game play and the experience of this rifle. I dislike the orange barrel tip, it was also difficult to take off so take your time. It's a 22mm inner diameter and compatible with the 22mm/14mm barrel adapter for the HUSH XL suppressor because it's perfect to add a molle ghillie suppressor wrap, you'll literally be undetectable to anyone in thick bush. I'm also able to fire 6mm steel BB's out of this rifle and it's deviating to any targets set up if the rifle is upgraded to 450fps+ Hope this review helps anyone out

Great Rifle but..

So I purchased this rifle a while ago and I have put maybe 600 BBS through it and it works just fine. It's a very accurate rifle, and has a nice weight to. it now here is my issues with it, The issue is the design itself is terrible its a completely Plastic body now that's understandable for how cheep it is but here is the biggest issue with the rifle the bottom tactical rail is just screwed into a hollow plastic shell, a shell with a seem. and thats where the screws go along that seem. so if your like me and pull a little hard on a Bi-pod or run into a wall it will snap right off. I fixed by taking the front weight out and putting 2 nuts on the screws and tightened them. its held strong for a few weeks now.
