Base rifle is the TM M16 A2, ZEKE M4 metal body kit, Systema Full Tune Up Kit M130, 9.6v 1700mAh battery, TN 6.04mm barrel, FIRST front sight mount base, KM M4 front sling mount, TM M4 scope mount base S II S 3-12 x 40mm A.O. airsoft sniper scope, FIRST sniper camo wrap, KM M16 sling, and KM silencer. I've had the gun for about 8 months and have been upgrading it myself in my spare time. I also modified the selector to only fire in semi-auto only because I don't believe in full auto sniper rifles. I went with the M130 kit because not only of durability concerns, but also that too much power will actually hurt your accuracy. This is the best balance between the 2 that I have found. The gun weighs in at over 12 pounds. Sniper rifles are heavy to add more stability which aids accuracy. Light rifles are good for carrying all day, but you do notice that they "float" around more, especially after running around which raises heart rate/intensity and breathing. I have not actually hung up paper targets and took measurements on groupings, but I do know that I can place every BB in my magazine in the area of a paper plate at 80 paces (I am 6' 2", 36" inseam). The 6.04mm barrel really helped the consistent accuracy and increased my velocity by about 10%. It does make the hop up more touchy though. I purchased a airsoft specific sniper scope for the reason that it is made for the shorter ranges of airguns. When I switch power settings, the target doesn't become blurry and the adjustable objective (A.O.) has lower range settings. It starts at 50 feet and goes to 150 yards. Real steel scopes may be nicer, but they don't work quite as well as the airsoft scopes. The KM silencer does a good job of muffling the the air "pop" but the upgraded mechabox does make quite a bit of noise. We play in some thick foliage so the flora and rustling noises cover up the single shot. The FIRST sniper wrap does an excellent job of camouflaging the gun and breaking up the outline. The gun is virtually invisible and it also helps dampen any vibration noises. Most of my shots are from about 50 paces due to the playing area's thick vegetation. My longest shot was 90 paces, and was a 1 shot deal.
