promaster(close but no cigar)
B2K4(not even close)
halo w/victory board
68/4500 pure energy tank/low pressure
not much that I see
Good efficiency and consistancy
good accuracy/with new barrel
easy to maintain
not many upgrades(for now)
Mag bashers don't like it
Picked it up after some of the flaws were worked out by the company and fell in love with it. It shoots like a dream. Stupidly light and tight makes this gun a snapshooters dream. Good accuracy with the stock barrel, but threw on my stiffi and the gun shot darts! As far as upgrades go, I really don't need anything on it. People say the trigger is bad but if you tune it to your liking, then who's to say it's bad. The board has all alot of modes, even though I keep mine at semi. Very fast stock board, but if you like to tweek, then there will be boards out for it soon. Nice feedneck and asa/ regulator. Kinda positions like a direct mount asa, which I love. And best of all, Easy to maintain. Very little parts that can screw up and as long as you have some basic gun knowledge, you'll be fine. If not, go online for all the breakdown/assembly/troubleshooting you could ever need. People may bash it 'cause it's like a Mag, but the automag had everything but speed going for it. Problem solved! If you get it, be ready to let everyone at the field hold it and/or shoot it(depending on how nice ya are). I had two people ask the field owner if he could order some for them after shooting mine.haha
All in all I think this gun rocks! It is at a though price range at around $400, but i have shot most of the guns in this braquet(pmr, Up'd Ion, epiphany,) and to my tastes, the mini is better. I give it a 10 becauseI just can't find a serious reason to give it a lower review.
I have used a stiffi and it works well with it, very accurate but could only be cleaned by silicone/rubber squeegee's. Currently I use a 10 inch Custom Product barrel for the size and easy cleaning, but it shoots just as accurate as the stiffi for half the price.
