Bought this gun about 5 or 6 (maybe even 8) years ago. I've put millions of rounds through it and it's still my favorite gun!
Any problems I've had, I've caused. I put a 10.8 volt battery in it, which resulted in the piston teeth shredding after the first 10,000 or so rounds (I believe it now has a Guarder piston in it now, which fixed the problem).
-VERY durable, never had an aeg last so long!
-Higher ROF with a 7.2 volt battery than my m15 has with a 10.8
-Relatively easy to disassemble
-Screws strip very, very easily. ONLY TAKE THIS GUN APART IF YOU ABSOLUTELY HAVE TO!!
-Every external upgrade costs a fortune
-Not every single internal upgrade for a version 2 gearbox will work with this gun
