I dont have the box for it, but if i remember correctly it was 400 fps. It is a single shot with a 15 count magazine. Quite durable, the same model is used for army simulation training. The gun isn't too beat up, i jus checked for chips and cracks. I couldn't find any which is amazing lol
there is no way it is 400 fps unless it is co2 powered witch it is not u said urself it might be 320 max and it uses .12 or .20 gram 6mm airsoft bbs witch u can find at any walmart.
I am putting this on my Watch List. My son is 10 and I am hunting him a most excellent Christmas Gift-he has been wanting one of these and I hope to be able to win it for him-I had a .22 by my 8th (my Dad was Career Army, so I am a TomBoy through and Through!!!) Birthday, so I think this would be OK for a 10 yr old boy!
