NEw barrel(stock is alright)
Hopper, i can walk up to 22bps but with the hopper i use it still cant keep up.
Trigger(wobbles side to side)
Grips-There really flimsy, i recomend dye sticky grips 3,(the are meant for this gun and because they dont wrap around the whole handle they dont rip)
I think its a great gun for starters. IF you maintain it(keep it lubed and clean) it should work excellent. Nice speed(with a good hopper) and if you upgrade the barrel its got fairly good accuracy.
I've played with this gone for 3 months+ and i havnt had many balls choped(maybe 5) and with a new barrel have had very little balls breaking.
The clamp neck is awsome because it it metal.
Despite using Co2 ive only had 1 o-ring break and i belive that was because i was shooting blanks for the first week when i got the gun.
Good gun =)
Overall i beleive thats this gun is a awsome starters gun, better than some of the tipp ive used. Accuracy is nice, speed, looks, are all really major attributes to this gun. For the price id highly recommend it.
