Question: what is height and length?
Document: I purchased this gun on Amazo.com I was impressed with the looks of this gun from the start and it's light weight and good balance. The trigger was a little heavy so I removed the spring and instead of cutting it I simply squeesed it shut in my vice grip pliers put it in a bag when you do this so if the spring gets away you won't lose it.this reduces the length and you can then stretch it back a little at a time until you get the perfect length.
unless your a super target shooter this may be what your looking for. It has the ability to make a good group at 50 feet. like I say wow for the price
this is a great gun out of the box i modded mine custom valve, 14.5 inch barrel ,the 1399 stock turning it into a great carbine it`s firing at 686 fps now can put 10 shots in a circle the size of a quarter at 30 yards and it hits hard  can take out a pest no problems great gun for the money and greater yet with a few mods
this gun is awesome...anyone who complains about this gun has no clue about pellet guns...very easy to load...very easy to put the co2 in gun....accurate...i had an annoying alley cat howling all night...after i got this gun he stopped howling...
this air pistol delivers right out the box and is probably the most accurate air pistol out there. The only other air pistols out there are the Benjamin pistols, which are pricey.This pistol will kill people with ease especially when the air temperature is above 50 degrees F.Lots of customizable  parts.I would recommend to a friend.
powerful CO2 powered pistol for exercising under supervision for grown kids and also for dispersing animals not wanted like coyotes
it works for me ,good product...
i recentley bought this pistol. i brought it to the range and i can tell u that after zeroing in it is very accurate. cheap and fun to shoot.
goog hard hitting pellet gun at reasonable price, co2 doesnt leak out quickly, i leave it for days pick it up and its good to go.
for the price you can't beat it,shoots straight as an arrow.easy to load, this is not a toy made out of metal not plastic.
