Things I liked: its been a year and 7 days since i got it and its survived hell and then some

Things I would have changed: the front sight will not move, making optics useless. also i've looked high and low for quad rail system for this gun, and i simply cannot find one!

What others should know: if you want a base rifle that will hold up, and keep you going... this guns it.

Things I liked: it shoots nice and it didnt need much hop up adjustment out of the box

Things I would have changed: The handguard where the battery goes the spring for the delta ring is very hard to get off but its starting to be easier as i do it more

What others should know: Get a butterfly battrey it fits good with the gun and you only have to take on side of the handguard off

Things I liked: Great RoF, love the sight, mag release, easy to adjust hop up, easily hit targets at 100 ft

Things I would have changed: Sometimes on semi it puts the safety on. but if you switch it to auto then back it fires just fine.

What others should know: I find the best way to open the hand guard for the battery is to wedge a screwdriver in it(This definitely takes off paint, but its the only way you can do it yourself).
