Crosman 30131 TR77 NPS – Guntype

This airgun is powered by nitro piston technology.

Nitro piston technology is one of the few innovations in the air gun world that makes your gun sport more breath-taking.

The caliber (the internal diameter of the bore, measured in diameters) is .177 (4.5 millimeter).

.177 caliber is the most common caliber for target shooting, plinking and small game hunting.

For more on how to choose the right air gun caliber for your game, see this post.

Crosman 30131 TR77 NPS gun type

This gun is a single-shot, break barrel gun with a rifled barrel.

Besides, the barrel is cut shorter than a typical barrel (that’s why the name of this gun is NPS with the letter “S” standing for “Short” and NP representing for “Nitro Piston”) for 2 reasons:

First, it gives the gun an authentic tactical look.

Second, with a short barrel rifle, you are good to go in the tight quarter or when maneuverability is of greatest importance .

Moreover, there is a muzzle brake at the end of the bore that redirects the gas to counter recoil.

A quick note about recoil:

Your rifle kicks back because the gas propels the pellet in one direction and also moves the barrel in the opposite direction,

So if you want to reduce recoil, you have to change the way the released gas goes.

The muzzle brake takes the form of 2 inches tubes screwed onto the muzzle and diverts gas 90 degrees around the barrel.

This is accomplished by the series of small parallel holes drilled in the tube.

The advantages?

Muzzle brake cuts recoil up to 50 percent which is no-brainer for most shooters.

Crosman 30131 TR77 NPS stock

The stock is all-weather synthetic stock.

Unlike woodstock which is heavy and easily affected by the moisture and temperature,

Synthetic stock is lighter and functions perfectly in any type of weather,

So it’s a great choice for young shooters with medium-build and for air gunners who want to own a maintenance-free air gun.

For more in-depth comparison between synthetic and wood stock, see this post.

The stock has a rubber buttplate to reduce recoil.

Besides, the recoil pad is removable to reveal the convenient storage space.

You can store plenty of things in there like pellets, paper targets, lens cleaning cloths etc.

Thus, it comes in handy when you take the gun out to the wood.

What’s special about this stock is its pistol grip: it orients the hand in a forward, vertical orientation, similar to the position one would take with a conventional pistol.

Pistol grips give you plenty of advantages:

First, you don’t need to raise your elbow as in a traditional shooting stance which is used with stock.

Therefore, it’s easy for you to maneuver in a house, stairs, around corners, etc with an air rifle with a pistol grip installed (especially in close quarters),

And it’s effortless to move, crouch, run, and hold it with one hand as well.

Second, it is much more intuitive to find the safety button.

Third, it is more convenient to hold your air rifle with your hand on a grip for a long time if you have a pistol grip.

Your hands will not get tired as fast as with traditional grip.

Also, it reduces strain on your wrist.

Finally, pistol grip allows you to have your hand close to the body and reduces your silhouette which is crucial in a hunting scenario.

In summary, a gun with pistol grip gives you an unfair advantage in the hunting field.


The Crosman TR 77 NPS uses .177 pellets as its only source of ammunition.

.177 pellets are cheaper than other types of pellets.

If you look at the pellet count box, you will see that you’ll get exactly twice as many .177 as .22 for the same price.

Thus, .177 is your best choice for long hours of fun plinking and exciting target shooting.

For more on the differences between .177 & .22 and which jobs they do best, see this post.

Cocking and loading

Cocking the gun:

First, put the gun ON SAFE, hold the gun by your side, then firmly tap the muzzle end to expose the breech.

Let the gun rest on your upper thigh and grasp the muzzle end.

Continue to pull the barrel down to its limitation to perform cocking action.

Loading the pellet:

With the breech opened after cocking, put the pellet (with the pellet’s nose lying forward) into the breech.

Then pull the barrel up to its original position until it locks and you are ready to fire.

Velocity, accuracy and power

Chrony tests give us the result as follows:

This gun delivers 1025 FPS with Crosman Premier Hollow point pellet and 1120 FPS with RWS basic lead pellet.

That’s pretty close to the advertised number and supersonic seeker will be very pleased with this remarkable velocity

For this nitro piston gun, different shooting tests have been conducted by various shooters with positive results.

The common shooting groups are: 1/2″ at 10 yards to 30 yards and dime size at 30-40 yards.

As you can see, this gun is extremely accurate with effective shooting rang up to 40 yards.

Moreover, with supersonic velocity, this rifle hits the target with serious authority

So it can kill crows, turkeys, possums, foxs, groundhogs, and rabbits with ease.

The incredible velocity power and magnum power combined makes this gun a perfect choice for small game hunter and pest exterminator.
