none really possibly a new barrel but i like the stock one.
Strengths:
Very accurate,quiet,light,efficient,easy to maintain, and alot prettier if you get the fade purple like me.:) Dont worry, people wont make fun of the purple, it looks cool when you get it
Weaknesses:
Well i only have had it 2 days and my sear is screwed
and it leaks CO2 bad, i used a 20 oz and it ran out in like 25 shots!!
no customer service and very bad 3-peices-of-paper stapled together make up the manual.
Conclusion:
Very good gun your an idiot if you dont buy it it outperforms spyders and pirhanas and even i think the 98c!
