i have this x-chamber on my model 98 and i am glad i bought it... i
live in
the northern part of new york but i still play all year round... i got
my
model 98 for x-mas along with a new barrel and the ACI 6 stage
expansion
chamber....i had no idea how to install it so i brought it to my local
store
( i also had to buy a vertical adapter-$19.99). i got my gun back the
next
day at the same time i filled my tank... when i went to play at my
neighbors
back yard, the temperture was -5 Celcius... usually i can get about 800
shots off my 20 oz when its this cold out... so i screwed in the tank
and
started playing.... i used 800 balls in about 3 hours and i thought my
tank
would be empty, but that didn't happen...i kept on counting all the
shots i
took after the 800th and there were 300 more! so now i can get 1,100
shots
off my 20 oz and before i could only get about 800... if you live in
states/countries where its really warm all year round or if you dont
play in
the winter, this product is not for you! the 6 stage x-chamber makes
your
gun look kind of goofy cuz it makes the foregrip 2 inches longer than
it was
before... many people say this is the best expansion chamber for all
guns,
and i think thats true...the 6 stages give the liquad the most time to
expand and your gun will not freeze up ( your x- chamber might get
kinda
cold though, so wearing gloves might be a good idea). Also if you use
nitrogen or Compressed Air, then you shouldn't waste your money on an
expansion chamber, cuz it wont have any purpose... You can find this
product
at www.countypaintball.com for $35.00 plus shipping and i think its
worth it
( i payed 50 for mine but i also got it installed for free from my
local
store)... I give this product a 9 out of 10 Splats... If it wouldn't
make my
foregrip so long it would be a 10 deffinately!
