UHC Super X-9 Spring Airsoft Rifle Manual
Super X-9 is the tactical model of the Super 9 and also features the ejecting shell function. When using the shells and rotary magazine, each pull of the bolt ejects the spent casing of the previously fired round. Sending the bolt back forward chambers your next round. With the use of an adaptor, the rifle can be converted to fire from a stick or cart magazine. The benefits of the stick magazine are that it does not cause you to loose any shells, and the capacity is 5 times greater! The rifle is as powerful as it is accurate. You can also add on the scope for additional accuracy.
UHC Super X-9 Double BoltSystem
When the guys at Airsplat asked
me to take a look at this airsoft gun my first feeling was apprehension. At the
same time, I’ve been itching to get my hands on a bolt-action and this
looked like the perfect opportunity. I’ve also been considering a
gas-powered bolt-action but have heard horrible problems about their
performance in cool weather. This I felt was a great time to give a
bolt-action a shot, and this one comes with both gas and spring bolts
The box art work is great and the box itself is well designed. If
you’re planning on storing the airsoft gun in the box when it’s not in use,
then the box seems up to the task.
For this price, you seem to be getting a lot of airsoft gun. The
package includes 2 bolts (a gas and a spring bolt), 10 cartridges, a
spring-loaded tripod with rails, hop up adjustment tool, a pack of bbs
, rail for mounting a scope, 1 mag for use with the cartridges, and a
second 25 round mag for use without the cartridge system.
Materials And Construction
tripod is metal and has springs to assist flipping the legs down, as
well as extending the legs. It includes two rails on either side
for mounting accessories and is secured to the airsoft gun via a short piece of
rail and a screw. It seems pretty solid with only a slight bit of
The cartridges are made from plastic with a rubber o-ring inside to
retain the bb. They are not very realistic in size or material,
but they do look like they would be fun for playing with. The
plastic they are made from seems durable as it doesn’t flex or crack
under moderate impact with a small brass hammer. The o-rings do
appear a bit loose inside the cartridges although I do not believe they
would fall out. We will test retention in a bit.
The magazine for the cartridges is a rotary design much like you’d
see with a real steel Ruger 10/22. The whole housing is plastic
and while fairly sturdy it might not handle a lot of abuse well.
Some flexing was noticed when tapping the mag with a brass hammer.
spring bolt cylinder is metal with a metal cocking handle and a plastic
bolt face. The air seal nozzle at the front end is rubber to
provide a good seal between the bolt and the hop chamber. The
piston assembly inside the bolt is plastic and uses a very basic
plastic cup design for the piston head (similar to department store
airsoft guns). The spring guide is also plastic.
the gas cylinder reveals that it is surprisingly hefty. The face
of the bolt is metal and features a metal air nozzle instead of a
rubber one. The bolt handle wiggles a bit, as the tolerances are
a bit loose. I also noticed they did not put an o-ring on the
fill valve which might cause it to spill propane while filling. I
did note that the packaging said the airsoft gun is compatible with green gas
and CO2 as well. Taking apart the bolt reveals a somewhat crude metal
spring guide and a brass gas cylinder. The cylinder appears well
sealed from leaks from the outside. Taking it apart shows that
the valve inside has 4 large holes and is made of brass with a rubber
o-ring. Given the size of the holes I expect the efficiency to be
fairly high, but wonder if a full mag can be cycled with one fill
of gas. If so, then I wonder if the holes can be tapped a bit
bigger to allow even more flow and increase the FPS of the
system. The cylinder itself is separated into a gas chamber and
an expansion chamber. The expansion chamber is not very well
sealed from the main chamber in that it just uses a rubber o-ring and a
metal plate with a hole in it. I would have rather seen a solid
plate machined into the cylinder, but that level of machining would
have influenced the cost of the airsoft gun as well. We’ll see if there
is considerable cool down due to this design later.
The hop unit is buried in the airsoft gun and is very hard to access.
With it removed I can see the barrel is not designed like an AEG or any
other Airsoft inner barrel. It is actually two pieces at the hop
unit and an odd diameter. The hop rubber is not a standard
length. This might make upgrading difficult.
The trigger housing and much of the trigger system is plastic.
The sear itself does appear to be metal; though I cannot account as to
how strong it is.
Construction of the scope rail seems to be on par with most airsoft guns in this price range with no complaints.
Front and rear swing swivels are attached to the faux wood stock via
the short underside rail in the front and a plastic retainer in the
back. Given the fairly light weight of the airsoft gun, this should be
adequate. The faux wood finish is not very convincing, and I
think it would have been better to have just made it in black.
The stock itself is weighted for realism and made from what appears to
be fiber reinforced resin. It seems pretty durable although I
suspect a very sharp-pointed blow would crack it.
You wouldn't expect a lot of features in a airsoft gun in this price range, but
surprisingly there are quite a few. First off is the ability to
use cartridges that eject when actuating the bolt. That’s pretty
slick. I know there are other airsoft guns out there that do this, but
not in this price range. The catch is that the shells are only
compatible with the spring bolt, as the gas bolt is slightly longer and
lacks the extractor and ejector needed to eject the cartridges.
Next is the quick change bolt system. If you run out of gas in
the field, or maybe want to change your FPS levels, then you just need
a swap of the bolt. Releasing a lever and the trigger guard under
the airsoft gun allows the shooter to slide the bolt out and swap it with
another.UHC claims it can be done in 30 seconds, and that seems
the back yard plinkers, the mag and shell ejecting system are fine, but
for skirmishing you need a larger mag and no shells. This airsoft gun has a
creative mag that snaps onto the side to allow 25 rounds of ammo to be
fed directly into the airsoft gun without the cartridges or cartridge
mag. This mag is compatible with both the gas and spring system.
Of course we can't overlook the scope and bipod rails on the airsoft gun.
Okay, before we get started lets look at the price point:
$134.95 at Airsplat.com as of the time of this article being
written. That's pretty cheap. It claims to be 450-500 fps
and have a range of 150-170 feet. Lets get started testing.
First the chronograph testing.
Testing was performed using .20g bbs and an Xcortech 3200
chronograph. With the gas bolt installed and the bolt at about 85
degrees Fahrenheit, we achieved 532 fps! Wow. Swapping over
to the spring bolt took just a few seconds. Firing through the
chronograph yielded 349.5 FPS. That's a might bit short of the
estimated 450 fps. I will say that the airsoft gun was considerably
quieter using the spring system over the gas system.
Next up, test the gas system capabilities. Now we know the
FPS, but is it consistent and is it efficient? We fired a full
mag though the airsoft gun on a single fill of propane with an ambient
temperature of about 65 degrees Fahrenheit, and still had enough gas to
fire off 10 more bbs . The efficiency seems good and the airsoft gun was
consistent as the variance in FPS was only +/-2 through until the last
shot. Given the cool temps I expected there to be noticeable cool
down creating a serious drop in FPS, but it stayed steady.
Tapping the holes in the valve might be a worth while venture to
increase FPS (if you feel you need it), given the fact that the airsoft gun is
efficient down to 65 degrees.
Looking back at the gas bolt we had issues with FPS. Testing
consistency yielded a drop in FPS from an initial shot of 360 fps, down
to 340 FPS with the last test shot (each shot declining in fps). Taking
the bolt apart showed that the piston head cup is the culprit.
The edges are a bit ragged and it does not seal well against the side
of the cylinder. Had an o-ring been used with a more traditional
piston head, I think the system would yield more fps. We cleaned
and relubricated the cylinder with some silicone grease (not oil), and
reassembled it. Testing the airsoft gun again on the chronograph returned
375 FPS with a variance of +/- 5 fps.
Range testing was done with both the gas and spring bolts. The
gas bolt was tested using .36g Madbull bbs. The pull on the bolt
was fairly light and short. The airsoft gun tossed them about 165 feet on the
first few shots with a flat trajectory before it began to drop sharply
to the ground. Continued testing showed that the hop unit was
erratic. Often the shot was very straight and flat, but there was
a bizarre flier or no hop effect every 3-4 shots. Taking the hop
unit apart did not reveal any defect in the hop rubber. I do
suspect that if you could fit an aftermarket inner barrel and a new hop
rubber that it would become more consistent. Testing with the
spring bolt and .25g bbs yielded a range of about 160 feet with the
same anomalies. I continue to suspect the hop rubber or hop unit
as the source of the problem.
The pull on the spring bolt was a
bit stiffer but still easy.
Accuracy testing was not done due to increasing poor weather
conditions as it has been raining day after day. What I have seen
from early testing is that when the hop unit is cooperating, hitting a
man sized target at 160 feet is no problem.
This airsoft gun uses nonstandard parts. This makes upgrading difficult,
and future repairs possibly difficult. I have found a few forum
postings on home-brew upgrades. I've tried a few with little to
no change in performance. The slight improvements were often
temporary too. The one home-brew upgrade that caught my eye, was
using an M16 length AEG inner barrel, some tape and a new hop rubber to
upgrade the hop and barrel system. This I have not had a chance
to test, but I feel would make this airsoft gun much more consistent than the
current two piece barrel that is in it.
This airsoft gun packs a lot of value in a very low price point. The gas
system performs very well in cool weather, and the spring system is
very quiet. Overall range is on par with most airsoft guns, as is the
accuracy most of the time. Add in the shell ejecting system and
you've got a great backyard plinker and a great first airsoft gun for someone
new to Airsoft.
With the bipod that is included and the scope rail, the airsoft gun seems to
be a decent entry skirmish airsoft gun. My reservations would be the
impact strength of the stock and the inconsistent hop unit. I do
feel that this is a good first airsoft gun to get your feet wet in the Airsoft
world of sniping before dumping large sums of money into higher end
systems like the Marui VSR-10.
The piston system should have been
better designed. Parts are not compatible with other brands / makes of
bolt-action airsoft guns.
It ejects shells… how much cooler can it get?
While testing nothing failed, I do
question how it would work as a long-term skirmish airsoft gun. For
backyard use it is robust enough, but I would have liked to see a bit
more solid construction in a skirmish ready airsoft gun.
FPS and range were on par with many other airsoft guns. The only real flaw is the inconsistent hop unit.
Even given the inconsistencies and the
lack up upgrade options, for the beginning Airsoft player this is a
great value. More veteran players might want to look at some of
the higher end bolt actions however.
