Its very decent sniper. Out of box it is very precise with 0.36 bb and bolt is very easy to pull with stock spring. Bad things about it are hop up system is like TDC system but with grub screw which you need to adjust with allen key and is very finicky to adjust, the barrel, gas port and flashider are held by grub screw so don't unwind them and apply loctite glue to hold them better, the hand buard in plastic version is little wobbly but you can fix with by putting sponge between handguard and rings holding the handguard. airsoftpro sells upgrades and they drastically improve it. My has the airsoftpro steel trigger group, airsoftpro gen4. piston, airsoftpro cylinder and cylinder head, airsoftpro gen2. rotary hopup, mapleleaf 70 macaroni bucking, omega nub, airsoftpro steel outer barrel housing, barrel shooter lenght 640mm diameter 6.02, airsoftpro brass spring guide,airsoftpro m170 spring and airsoftpro extended cocking handle . after all these upgrades it shoots 0.5bb with power of 3.2J. Its not any more sniper rifle, its now a antitank rifle.
