I just got it and it was astounding. I was wowed when i first shot it. IT was so very acurate. I used my PMI perfect berrel that i used on my TL and its accuracy was comparable to an autococker and the like. The rate of fire was very fast so fast i chopped a ball( the only ball i broke all day) but i was shooting 12 bps on full auto without my revy on (im very stupid about turning things on). The batery life is very long i used it for about 2 weeks tested it and the battery was still overy half way good and it is very easy to replace. This is a blow forward gun not blow back the air comes up through the pnumatic sylinder and blows the bolt forward this I call a blow forward gun. You never have to cock the gun either thats kinda neat
Weaknesses:
not a whole lot the Electronics are a hassle to get to to change modes but thats not really necessary and mine developed an air leak but it was my fault for turning the reg up to high (remember keep it below 350) i cronoed it at 450 wow but it was easily fixable
Conclusion:
This is a great gun for the 450 i paid for it it shoots fantatically and now all my freinds want one. It is compareable to a shoker and much better than a bushmaster. It is a better value than the Impusle becouse you get all the modes like 3 and 6 rnd. burst turbo and full aouto for $450 and the Impuse you have to pay and extra 100 for it but shoots just as good I love it
