Today we begin looking at the Turkish-made Kral Puncher Breaker precharged pneumatic (PCP) repeater. The one I’m testing is a .177, but they also come in .22 and .25 calibers. In the caliber I’m testing the magazine holds 14 pellets. The price is the same for all three calibers, at $500, which pits this rifle against the Benjamin Marauder.
The big question
Okay, let’s address the big question that’s on every reader’s mind. Where do they get these outlandish names?!!! Puncher Breaker? Are they kidding? It has to sound better in Turkish, don’t you think?
Kidding aside, the Puncher Breaker Silent Synthetic is a bullpup with a sidelever action. A walnut stock is also available for more money. I tested the full length Kral Puncher Pro for you last year, and the action of this rifle is not much different. However, the rest of this bullpup differs quite a bit.
It weighs just 7.4 lbs. which is light for a repeating PCP. The bullpup design shortens the overall length to just 29 inches, putting all that weight into a small package. A shooter who is unfamiliar with bullpups might think it feels heavier. But trust me — it is light.
Despite the short overall length, the barrel is still 21 inches long. That means we should see good power from this rifle. It is advertised to have 18 foot-pounds in the .177 caliber I’m testing. That would be a 10.65-grain pellet (H&N Baracuda Match) moving 872 f.p.s. I can’t compare this rifle to the Puncher Pro I tested, because that one was a .22.
Kral included a test target that was fired with this rifle. On that sheet they included the velocities of each of the 6 pellets fired, and they ranged from 948 to 960 f.p.s. They don’t mention the weight of the pellet they used, but the graph in the manual says it was a 7-grain RWS pellet. That would be what I would test it with.
I chose the model with the synthetic stock for testing because I tested the walnut stocked model of the Puncher Pro. We saw how nice the woodwork was on that one (the Turks do fantastic woodwork!), plus the walnut version of this bullpup weighs almost a whole pound more, at 8.2 lbs. I wanted the lighter weight.
The synthetic stock has an additional advantage. It has a compartment for a spare magazine inside the front of the forearm. Push a spring-loaded button for access. You don’t get that on the walnut gun.
Single shot tray
The rifle comes with a single shot tray that converts the action to single feed. I will try it for you and see how easily it works. If it works well, I may do some accuracy testing with it installed. Maybe a comparison group with the single shot tray against the best magazine-fed pellet?
The rifle accepts a standard 200 bar/2900 psi fill. That means it’s going to be fairly easy to fill, although because it is a repeater I think you will shoot it a lot more than you might shoot a single shot. I recommend filling from a tank and not a hand pump. Not that it isn’t possible to fill from a hand pump — you’re just going to be filling it a lot, I think.
The Puncher Breaker fills with a proprietary probe. There is no standardization — you must use Kral’s probe or one of identical size. But there is something you need to know about this probe. Kral has been shipping their probes with a set of clear o-rings that are slightly too small to seal the fill port. They sometimes work but usually they don’t. Pyramyd Air sends black o-rings in the parts with the rifle to replace the clear ones, and they seal well.
Power is adjustable via a knob on the right side of the action. There are 5 white marks to indicate power levels, but there are no detents. You can adjust the power anywhere between the minimum and maximum settings. I will test this feature for you in a meaningful way, but nobody will ever live long enough to test every pellet at every possible power setting. Once I establish the parameters of the power range, I will be going for the best accuracy.
The barrel is shrouded but there are no baffles inside the shroud. The end cap is shaped to strip off the excess air, so we will see what the discharge sounds like. The title of the gun is Silent. Let’s see if it is.
Of course the Puncher Breaker comes without sights. The scope base on the rifle is permanent and only accepts Weaver-type scope mounts. I have a new Weaver mount to show you, so perhaps I will use it on this rifle. Whatever I use has to be tall because of the bullpup design.
The forearm has a threaded brass boss that accepts a short Weaver rail for mounting a bipod. The rail is provided with the rifle. I may mount one for the accuracy test, though I do like sandbags better for stability. I’ll have to think about that, because bullpups and bipods don’t go well together, except in the dreams of mall ninjas.
I really like the small size and light weight of this Puncher Breaker Synthetic bullpup. Of course there are key things to establish, such as discharge noise, shot count, power and accuracy. If it holds up, this may be an exciting alternative to consider for those who are looking to enter or to advance in the precharged world.
