"Bought this gun a few weeks ago and after running it in 3 major games i thought I would do a review. Out of the box it looked well made stury no scratches or dings. I did notice the bolt cover was bent but i didn't mind was easier to access hop up when it sticks back instead of holding back on the charging handle. The hop up took a few turns on the dial before it seemed to lift the bb but once it was on i was really impressed with the range i was getting. my shots were more consistent with.28 bbs The kick on the gun (which is why of course I bought it) was great!!! Especially in full auto you can really feel the gun move. The gun did chrono low like 318 out of the box so even though it had good range it took the bb a little too long for my taste to get there. Taking this gun apart sucks!!! because of the way the gun is wired the wires get in the way when taking if apart and putting back together (make sure you have a AR tool makes it eaiser). Gun came with a 11.1 battery but i would suggest buying another one cause my last about a half a day of full play. Overall i'm very happy with the gun and all my friends that have shot it have been impressed. I added a DD rail to mine with kac suppressor. Actually thinking of getting another and having evike install a 120 spring in it.

1 Well made
2 KICK!!!
3 Good range.(I use .28 with mine)

1 Low Fps
2 wiring position
3 no sling adapter

1) Nice look & feel
2) Good Accuracy/FPS/RoF
3) EBB feels great

1) Tappet plate broke on first day of use and jammed the gear box.
2) Bolt cover bent and jammed the gun after 15 minutes of use on the second day

I haven't been able to use it much in the 3 weeks I've owned it, as it has been broken most of the time. When it works, it works well. I hope my experience has been a fluke and isn't reflective of the overall quality from Bolt.
