First Look At The Weihrauch HW100 Bullpup

Just arrived in the HAM offices is a new PCP air rifle – the Weihrauch HW100 Bullpup. HAM readers first discovered this compact model  in our coverage of the 2019 IWA OutdoorClasics trade show in Germany.

Now it’s arrived in the USA and we have 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.

We chose the shorter, carbine-length version to review in .22 caliber. HAM Tester Doug Rogers can’t wait to get his hands on it!

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. 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.

 

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. The HAM Team chose to use this for our scope mounting.

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.

Without the HPA tank in place, it’s easily possible to see the trigger blade assembly and bar connecting back to the sear section of the trigger. The screw thread left is where the HPA tank screws into place.
