Again, not really a rifle but great for CQB from what I hear, the Well G55 (MP5K) it's a clone of the Maruzen MP5K and a pretty exact one at that. Mags are pretty cheap (25-35$ from what I have found), and it is very efficient on gas, some reviews I have read say that the gas lasts at least 5-6 mags worth of BBs. Insane rate of fire too.

It's very cheap in the US (less than 100$) but it only comes with 1 22 round mag. I would think it would be about 250-300$ here.
