Crosman 1077 Repeater Review

Overall Rating

Traditional styling.
Standard sight mounting groove.
Simple, well operating mechanism.
Light and handles pleasantly.
Easily used both lefties as well as righties

Looses power quickly when using the small CO2 capsules.
Horrid standard sight.
Original sight permanent adjustment is nearly impossible.
Trigger pressure is fairly high, which invites jerking.
When rapid firing the weapon jumps ever so slightly.(1.30 to 2.00 o'clock)

After having tried two specimens of the NightStalker variety, I gave up and decided to go with the tried and true 1077 Repeater.
My initial experience was one of pleasant surprise and that lasted until I attempted to adjust the standard sight. The initial grouping at 10 meters was a nice and tight 2 cm and had I not had a regimental dinner the evening before, I might have been able to whittle it down to within a single centimeter or less. I consider this quite satisfactory for a weapon in which the barrel is not threaded into the main mechanism of the rifle.
Then the horror started with adjusting the rear sight. Cheap is hardly the proper designation that applies in this context. It is much worse than that, and after I managed to to get it to finally stick in its desired position, the tightening of the screw caused it to shift again, causing another cycle of adjusting and re-adjusting. Solution to this was my abandoning of efforts to effect adjustment of the original rear-sight, subsequently my headlong dash back to the store and purchase of a cheap telescope sight.
After this, the next vexation reared its ugly head. At 15C ambient air temperature and after about two clips at rapid fire (12 shots at <5 sec), the muzzle velocity dropped considerably to the point of being useless for enjoyable target practice let alone serious application for anything else.
Waiting for about 5 minutes to let the CO2 cartridge warm up and thus repressurize corrected this, but it was either this or discard the less than half used cartridge in favor of a fresh one. In the end I resolved this by purchasing the AirSource adapter. This however, makes the whole contraption rather unsightly, not to mention rather vulnerable to damage. It does not take a Herculaean effort to to break the adapter and certainly when firmly shouldering and holding the rifle while gripping the AirSource capsule, irrepairable damage is very easily done.
In the end I designed an aluminium enclosure for the AirSource capsule that snugly fits the existing stock well enough to allow for proper protection of both the AirSource capsule as well as the exposed parts of the adapter. This contraption gives the rifle a somewhat 'pregnant' look, but it definitely makes for better handling and with the aluminium enclosure acting as a heat-sink, it makes for a very consistent muzzle velocity (and clammy fingers, I might add.).
I am working on piecing together an in-line solution for aesthetical and practical reasons.
As to the functioning of the rifle itself, I have no further adverse findings. It is basically accurate and after about 2500 shots I have encountered no mis-fires or feeding problems that so annoyingly plague the NightStalker.
I have used the basic .177 wadcutter pellets as well as the heavier domed and pointed pellets and found them to all work very satisfactory and accurate without any pellet-jams or mis-alignment issues as experienced with the NightStalker.
The main issue with CO2 rifles, being the condensation of moisture in the barrel is not any better or worse than with any other comparable rifle although the barrel being fully enclosed is subject to some measure of insulation which requires regular cleansing with a dry or barely oil-dampened piece of cloth prior to storage after being done shooting for the day.
The internals are easily and conveniently accessible for whatever cleansing as required and the clip-holder insert has not given any problems.
The experienced 1.30 to 2.00 jumping at rapid-fire takes a tad getting used to, but is easily compensated with a little practice.
On the whole this is a very pleasant and accurate weapon when equipped with even the cheapest of a telescope sight.
It is very easily and accurately handled by my 10 year old son, as well as my 8 year old daughter who are diligently saving their pennies to get one of their own.
I can easily recommend this as a good and affordable entry-level CO2 rifle and as an enjoyable 'plinker' for the more experienced user.
