i bought an mr1 and am pretty happy with it, but there are a few problems. first, the cocking knob obstructs the ability to look down the sights. second, the stock SUCKS! it is cheap plastic and doesn't let you look down the gun. i put a stock attatchment on the co2 tank and it works perfectly. i also put a 29 inch barrel on it and it is amazingly accurate. i plan to get an A-5 and use the MR1 as a sniper

In conclusion, the mr1 can be great (with a few upgrades)
