The Hatsan BullBoss bullpup PCP includes the Quiet Energy suppressed barrel which has been tested by us and shown to severely reduce the report of the gun. It's quiet enough to fire without disturbing your neighbors if you'd like to practice in the backyard. The BullBoss includes Quattro Trigger that is a two stage fully adjustable match trigger. You'll love the weight displacement of the bullpup design that really distributes the 8.6 lbs of the gun well to make this a joy to shoot and creates a situation where follow-up shots are incredibly easy as you can keep the gun shouldered while operating the smooth side lever of the BullBoss. A lot to love about this new bullpup from Hatsan USA.

Pros
Accurate,light.. good power.can be silenced real good !lol, and price was right!
Cons
Auto safety after every shot , but you can mod it.
Get this gun, well worth it and a blast to shoot, very very accurate, same results on 3 different pellets so far and one of them being the fx slugs, the work great in this gun.
Pros
Awesome gun, very accurate and looks good, I use jsb exact king Diablo 25.39 in 25 caliber and shoot all 4 clips at a quarter size group at 50 to 75 yards and I get 27 shots at 900+ fps and an additional 9 shots (1 more clip) just below 900, high 800s with just a little hammer spring adjustment, turned it counter clockwise about 2/3 rds, you will need a long 4mm allen key (at least a 6" one) for the hammer spring adjustment and an additional 2.5 mm allen key (6" long) for the 3rd screw on the trigger adjustment, hatsan gives you a 1.5mm allen key for the first 2 screws on the trigger adjustment, what else is there to say, gun looks and shoots great, tried the hatsan regulator from Amazon and I was getting only in the low 700s for fps with multiple adjustments, maybe it was a bad regulator, I actually had 2 of them and one would not go all the way in the cylinder so long story short I returned them both, gun works great without it, it's a personal preference, I would highly recommend
Cons
Hatsan should also give the adapter for the filling probe but just make sure to order one from airgun depot when you purchase the gun, also hatsan should also give a 4mm and 2.5mm allen keys for the adjustments
TRUST NO ONE MORE SCAMMERS WORK THIS HOBBY LOOK HOW AMEER WORKS THE DELAY SCAMHES FAIR HES RUINING BOTH COMPANYS
SCHEME
Pros
THE GUN IS GREAT IT JUST NOGOOD WITHOUT PELLETS PYRAMYD AIR HAS AMEERLAZY GUY DONT KNOW HIS JOB CANT KEEP STOCK IN AT AIRGUN DEPOT EITHER THIK MAYBE HE SHOULD ONLY WORK ONE COMPANY INSTEAD OF BANKRUPTING TWO COMPANYS
Cons
SELL THESE GUN WHERE YOU CAN GET AMMO TOO
Easily tunable to achieve incredible accuracy. Very balanced on the shoulder. Very capable of longrange repetitive accuracy. Seems to like pellet or slug ammo without issue. JSB King Heavy, Predator Polymags both produced one hole accuracy at 50 yards.
Pros
Extremely accurate, easily tuned. Compact, Balanced. Great PCP for the price.
Cons
Add Air Regulation.
it loves 33.95gr diablo exact king heavy , sighted at 120' with bug buster scope on 50' small bore target, amazing . It will throw 38gr .254 AVS dish base slugs almost the same without recalibrating the scope ,they chamber a little stiff but are very accurate . These are pricey but real smashers.as one person said "they hit likeThor's hammer." I imported the wood model to Belize for pest control with bipod .this is an awesome deadly weapon . I also have been forced to shoot this weapon left handed because of retinal hemorrhage , not a problem . I love love love these guns. be sure to have a strong backstop.
Pros
everything , I own both plastic & wood stock models in .25 cal.
Cons
plastic stock model has plastic side cocking plate which I broke & had to replace with a metal one. the wood stock model came with an extra side mounting rail for my light .should be the same with the plastic stock .
Pros
Awesome gun very accurate
Cons
Loose screws, and mine did not come with the free sling?
Get plenty of pellets, because the gun is really a blast to shoot.
Pros
Great gun to learn the ins & out of air gunning, fun to shoot, accurate, and easy to work on.
Really good knockdown power, however it seems as if I am getting Flashpup performance as far as the specs of the gun in 25 cal shooting 850 which is a 150 below advertised FPS.
I’m happy with the gun, just wish I could see higher FPS when adjusting the Hammer Spring, I see the loss in power but not the increase.
Cons
Only have seen 850 FPSwhich is under the advertised 1000fps I was using the Baracuda Hunter 27.47gr.
Had to shim my scope, because it was shooting low at the max setting.
Does everything I require from .25 without busting my budget.
Pros
One of the best overall values out there.
for all the right reasons.
Cons
No issues so far.
2500 shots approx.
This was my first airgun I have ever bought. It was not a disappointment, I would highly recommend this to anyone who is just getting into airguns. It is a lot quieter then I expected it to be .
Question?
Login to ask someone who bought this product.Rec'd .25 Bullboss with air cylinder that appears scratched as if from twisting it into the bands when assembling/disassembling. Also, bluing on cylinder is very inconsistent. The rest of the gun looks great. Wondering if this is typical for the Bullboss. Have a Barrage that arrived in mint shape. Thanks!
asked Mike from USAHi my question is in the 177-Cal can you shoot slugs in it or not this may be a silly question but i be told that some of the air rifles can't shoot slugs as i am new to pcp air rifle because i have seen fx have innerliners one for pellets and one for slugs, so has hatsan have the same thing for pellets and slugs?
asked George from United Kingdomcan you put a regulator on the Bullboss?
asked Roy from USAYes I believe huma makes a regular for the bullboss, there is a video of it on YouTube
Manny from USAHow is the acre sAccuracy
asked James from USAOne review mentioned a 3d printed cheek pad and several wishing there was a cheek pad. Is there an adjustable cheek pad available?
asked Edward R from USACan this be filled off a scuba tank?
asked David from USAOF COURSE, WITH THE RIGHT FITTING S
antonbend from USAwhich fill probe is needed for this airgun? why does the at44 qe come with a fill probe and seal kit and not the bullboss? i do not see a hand pump as an option to purchase in the pcp accessories or a fill probe
asked Joe from USAIncludes quick-fill nozzle & air cylinder discharging cap supplied in the box. The quick fill nozzle is the fill probe.
Mark from USACan you shoot slugs 25 cal in this gun?
asked Sonny from USAYes/ They will probably have to be single loaded. They will probably be too long for the magazine.
Mark from USACan you air the rifle up by using a air compressor like one you would use in your garage ?
asked Sonny from USANo.A garage air compressor delivers air at 150 psi. You need air at 3000-4500 Psi. A high pressure compressor.
Mark from USAWhat is the muzzle velocity when using JSB Diabolo Exact King Heavy MKII .25 Cal, 33.95 gr?
asked Simon from USA
I'm most amazed by the length of the barrel, 23" inches long and the overall is just under 37" and I'm getting 4 magazines per fill and it only takes me down to just under 100BAR.
Pros
I love the looks of this PCP, it is sleek and looks tactical! This rifle is very accurate, once sighted in it's almost impossible to miss with this rifle and it hits so hard, that I had a neighbor stop over because he thought I was shooting a .22 powdered rifle, when I showed what he thought was a rifle report, was actually the pellets striking the target, he was amazed.
Cons
Wish it were semi-automatic.
