"I've put maybe 100k BBs down range with this and I love it. Great intermediate gun, out of the box shooting right around 415fps, so a little high for most fields, it did drop a little but not much. I also use either .25s or .28s pretty very good consistency. The fuse did have to be replaced it and it does come with 30A fuse, but you can pick them up at a local auto zone. Slight wobble, no biggie. Iron sights are standard m4 flip ups, they work no issues. All in all, not bad! Definitely recommend.

"I love this gun so much... I really don't know what people are talking about when they say the fuses blew, mine did to, but the gun comes with an extra fuse (30amp), and needless to say... the fuse that is already in the gun is a 20a fuse... so its not going to last with anything above a 9.6v... and if it shoots to hard, buy one of the spare upper gearboxes, then cut the spring down just a little bit, that's what i did, not I have a 427fps gearbox (the stock one) and a 349fps gearbox, also... buy an enlarged stock, because the default one] does not have a lot of battery room... the biggest battery it will hold is an 11.1v 1300 at most... so, 1. replace your fuse with the 30amp right away 2. buy a spare gearbox to experiment with 3. buy the ICS MTR S1 (417/416 style ICS Retractable Stock).

"I love this gun, hasn't failed me once for the last 3 months, I can use it anywhere by just making a few changes on the gearbox... 10/10 and I definitely recommend this gun
