It is not recommended that the BullMaster be operated from the left-handed shooting position. The bolt located on the right-hand side of the rifle cycles with each shot fired and may cause injury if operated left handed.

*We do not recommend using Weaver mounts.  Some weaver/Picatinny mounts may not fit the weaver sections on the rail.

Please Note: All  Hatsan semi-automatic airguns are designed specifically for skirted pellets only.  Slugs or other non-skirted rounds will not cycle properly.

The Bullmaster is Hatsan's answer to airgunners who want semi-automatic PCP airguns that combine fast shots, with high maneuverability and penetrating power.

This bullpup's claim to fame is its unique gas operated action (as opposed to electrical) which adds greater reliability and longevity than other semi-auto PCPs on the market. Loaded with features, the Bullmaster includes an 11mm Dovetail/Weaver scope rail and a Weaver accessory rail to mount a laser sight or flashlight. Built for accuracy, the Bullmaster features a rifled and choked barrel which is fully shrouded. These features add up to a gun that’s accurate, naturally quiet, and ideal for backyard target shooting or small game hunting.

Each Bullmaster includes 3 rotary magazines (14-shot .177 and 12-shot .22 caliber) so shooters spend more time shooting instead of reloading. The rubberized stock has 2 magazine carrying slots so the extra mags can be carried on the gun. The stock also features an adjustable comb, and grooved pistol grip and foregrip which houses the built-in pressure gauge. The removable 500cc tank fills to 250 BAR (3,625 psi) via the standard Hatsan fill probe. Power hasn't been sacrificed for size as the Bullmaster can launch .177 pellets at 1,100 fps, .22 calibers at 1,000 fps, and .25 at 900 fps. Each rifle includes a hard case for keeping your gun safe and sound when not in use.

If you want a Bullpup that can deliver fast semi-automatic shots, with ergonomic design and maneuverability, choose the Bullmaster by Hatsan.

Things I liked: Looks are different which I liked but others would say its ugly. Balanced well when shouldered but is on the heavy side. Mine was a .177 cal.

Things I would have changed: Make sure the rifle cycles before it is shipped. Try to lighten it up atleast a couple of pounds. Add a removable airtube.

What others should know: This rifle did not cycle all the time. The mags didn't seat well in the breech. I sent mine back and Pyramydair was awsome to deal with. It was not backyard friendly but then again some backyards are bigger then others.

Things I liked: Semi-auto; unlike some reviews, it works and works well.

Things I would have changed: Add QE to make it more quiet, still not super loud but not quite backyard friendly

Things I liked: I purchased the Bullmaster in .22 caliber back in May (switching from the Gauntlet since it was apparently being chiseled out of stone at the manufacturer) so I've had some time to put well over a thousand rounds through it--and I have to say I'm pretty impressed with the accuracy and the semi-auto function of this bullpup. I've had zero problems with it cycling (or jamming) and I've fired it as fast as I could pull the trigger on multiple occasions.

Things I would have changed: The weight, as others have stated it is extremely heavy, and becomes even more so when you add your optic of choice.I feel sorry for any hunters out there lugging this around, I bought it for target practice and plinking, so at the end of the day it's not as a big of a deal to me. I also have to admit that I didn't care for the magazines. While functional, they are a pain to load, and all three had extremely different tensions in the springs--from so easy I thought it was wore out to "omg I think I have arthritis" after reloading it a few times. An adjustable trigger would have been nice as well, esp. considering the price tag on the Bullmaster (and considering my Gamo Urban came with one and I had only spent 220.00 on that PCP).

What others should know: This PCP is NOT pellet picky. I've added pictures of four different pellets I used, from the very inexpensive Crosman Premier HPs to the H&N Rabbit Magnum II and I would use any of them again (esp. the Diabolos, 5 shots leaving one jagged hole, which is consistent with other shooter's testimonies out there). Since I did spend a thousand dollars on this bullpup, I would be remiss if I didn't point out that the case is useless once you mount an optic, which you HAVE to mount an optic because this platform doesn't come with on-board sights... speaking of the case, that is how P.A. shipped this expensive bullpup, in the case inside a box with zero packaging; so the bolt punched through the foam inside the case and dented it from the inside out. My advice to them is spend a little extra money for packaging. Bottom line, would I buy this again? Absolutely.

  • Ronbow from USA asked:

    How is the accuracy compared to the Gladius? I have the BT65QE, and it is awesome.

    • Tyler from USA:

      The barrels come from the same place, and the accuracy I've seen from these has been comparable to the other hatsan pcp models

  • Lucius from USA asked:

    Your website shows the option to purchase this gun in .25 cal but the product description says its only available in .177 and .22. Which is correct?

    • Tyler from USA:

      The .25 is available, looks like PA just hasn't updated the descriptions on their site yet

  • gol from Japan asked:

    I have problem with my hatsan bullmaster..the magazine will not rotate at all..

    • ROBERT from USA:

      Same here. fired 200 rounds perfect right out of the 201, mag failed to cycle.

    • Samer from USA:

      I have the same problem, only shot through about 3 full magazines. Now its no longer semi auto. Very frustrating, may have to return
