The Maruzen series rifles are some of the best in the sport. The APS was pretty much on top of the game until the M24 came along to give competition. You would not be disappointed in the Maruzen rifle.
It is not too hard to upgrade the rifle to 500fps, but it can be costly. Some will tell you to put a spring in it, but you need much more. Durability upgrades (ie reinforced parts) will cost you right now, but it is better than having your gun geek on you at a dramatic moment.
