The Weihrauch HW100 Bullpup was first shown at the 2019 IWA OutdoorClasics trade show in Germany. Now it’s arrived in the USA and we are looking at one of the first guns received by Airguns of Arizona.
Perhaps surprisingly, the Weihrauch HW100 Bullpup is a version of the HW100, with its metal receiver. It’s not based on the more recent HW110 which has a synthetic receiver. It’s available in both .177 and .22 calibers and also in short and long versions.
The carbine version features a shorter barrel, together with a smaller HPA cylinder. This will mean less power and a lower number of shots. However the upside is to be found in the outstanding handling available in this compact package.
For testing, we mounted an MTC Viper Pro 3-18 x 50 scope using Leapers UTG Pro rings. There’s a choice of scope-mounting options. Regular airgun grooves are machined in the top of the receiver. However a separate Picatinny rail is screwed screwed onto it by default. We chose to use this for our scope mounting.
We also attached an UTG TBNR bipod to the short, removable Picatinny rail under the forend.
The Weihrauch HW100 Bullpup has a mid-mounted sidelever action. It’s located – as expected – on the right side of the gun and is conveniently located near to the trigger blade.
The HW100 Bullpup is supplied with a Weihrauch-manufactured silencer permanently-attached to the barrel. It also comes complete with two magazines, a fill probe and degassing tools. The HPA tank is removable – it unscrews like that of other Weihrauch PCPs. The front lower Picatinny rail is also supplied separately, with its fixing screws.
The trigger of the Weihrauch HW100 Bullpup Carbine is a two-stage design. The pull weight averaged just 14.7 Oz in the sample we tested. The first stage was very light. However – despite the light pull weight – the “stop” for the second stage was very easy to feel. Release was then clean and precise.
All bullpup air rifles with a mechanical trigger separate the trigger and sear assemblies with a long rod. This is seen in the photograph below for the Weihrauch HW100 BP Carbine with the HPA tank removed.
Overall, the short length (23 Inches) and compact design make this new air rifle a delight to handle. The Weihrauch HW100 Bullpup Carbine shoulders well and is fast and easy to bring onto aim.
This is enhanced by the molded pistol grip which – like that on other Weihrauch PCPs – is outstandingly comfortable and obviously designed with considerable care. The trigger guard has cut outs on either side. These position the user’s trigger finger safely away from contact with the trigger, yet leave it as close as possible for rapid access when ever a shot need to be taken.
The Weihrauch HW100 BP Carbine is an individualist’s air rifle. It’s not trying to offer the most power, highest shot count or maximum versatility. What it does offer, however, is superlative quality of manufacture, outstanding handling and huge practicality. It combines this with excellent accuracy and enough power for most users. And it does it with great style!
If you’re looking for a light, quiet, compact PCP air rifle that’s “out of the box ready” with the minimum of fuss, the Weihrauch HW100 Bullpup Carbine definitely fits the bill. And it’s available at Airguns of Arizona now!
