Spyder MR2 (heavier and louder and more expensive)
Smart parts SP1:
Rap4 extendable M4 stock
16 inch JJ&Ceramic barrel
Hopper with eyes
can run on Co2
Smart Parts doesn't exist anymore.
Basically: Got this thing when i turned 16
It is a very quiet dependable marker. Only ONCE have i had to run with a backup. This gun is virtually indestructible; its been rained on, dirt filled, and still shoots fine.
Accuracy: the stock barrel is okay, but if any paint is in it it will swirl around like nobodies business.
Battery life: This thing will run forever on a battery. I've played literally three 4 hour days in 3 different weekends and never had to change my battery.
Air: This is a personal preference. For the type of paintball i play i really don't care about HPA it costs more and Co2 works just fine. I have it attached straight to the gun, and a 20 lasts me all day long.
Quiet: It is SO quiet. You will think you are low on air with how quiet it is. I have a 16 inch JJ and ceramic on mine and it is almost silent. Smart parts did well with this gun.
Body: It is small and durable, it's not heavy or anything so you don't have to worry about that. If you do have a stock and along barrel on it it can get tangled in brush, etc.
The one thing i don't like is i cannot tell when i'm getting low on air.just because it is a very consistent gun. I have NEVER chopped a ball with this bolt; i actually tested it by putting my finger in there and the MOST damage it will do to a CRAPPY Walmart paintball is DENT it slightly.
Great backup if you are a crazy mil simmer, and a great gun if you just casually play with friends in the woods. Very dependable; never chops, decent little gun. I recommend it to anyone as a backup, especially at this price. I guess now its a GOG gun, but same thing basically.
