Take A First Look At The New Umarex 850 M2

The Umarex 850 M2 was among a huge number of new products introduced by Umarex USA at the 2020 SHOT Show in Las Vegas. It’s a CO2-powered, magazine-fed, bolt action repeater.

In fact, this is not a completely new product. The Umarex 850 M2 is an up-graded version of the Hammerli 850 AirMagnum. Both share a lot of similarities, both are made in Germany, however the new Umarex-branded model includes a number of worthwhile improvements.

Both 850s are powered by a 88/90 Gram CO2 cartridge. This is enclosed in a pull-off front cover to the buttstock.

HAM tested the Hammerli 850 AirMagnum in .22 caliber some time back. We liked it lot and it earned a HAM Bronze Award. So we’re glad to have received this Umarex 850 M2 in .177 cal. It’s going to make an interesting comparison in a future test review!

The 850 M2 has a more tactical-style look than the Hammerli version. There’s a selection of short Picatinny rails on the front, suitable for mounting a bipod, flashlights and/or lasers.

We mounted a Leapers UTG TBNR bipod on the lower rail. This worked fine and – somewhat to our surprise – the pull-off forend formed a quite solid mounting point for the bipod.

The 850 has always been known for offering usable iron sights and the M2 version is no different. There’s a hooded front sight with red fiber optic, together with a ramp-type rear sight with green fiber optics. There’s no windage adjustment however.

While some will rejoice at this provision of open sights, The HAM Team immediately mounted a scope! We installed a trusty – and much used – Leapers 3-9 x 40 AO scope with medium rings, thinking this would be typical of the scope chosen by many 850 owners.

Several things became evident from mounting this scope…

Firstly – as we can see above – the 850’s scope mounting rail is unbroken as the rotary magazine is enclosed below rail height. This gives complete freedom of scope ring positioning in a way that is unavailable with most “broken rail” magazine-fed breeches.

Secondly, clearance between the scope bell and barrel was perfect. There’s just a tiny amount of clearance. Although the frear sight did not hinder scope placement, we removed for appearance sake. Just one screw holds it in place.

Mounting the scope also proved the utility of the cheek riser supplied with the Umarex 850 M2. This clips over the buttstock and provides a good cheek weld for scope use.

It’s easy to un-clip too and so can be removed easily if it’s desired to move back to open-sight shooting.

The Umarex 850 M2 incorporates neither a silencer nor shroud. However the barrel nut can be removed to reveal threads for installing an Umarex Compensator. Below we see the barrel nut partially unscrewed.

There’s no question that the Umarex 850 M2 will remain an enthusiast’s choice among air rifles. After all, it costs pretty-well the same as a shrouded, HPA-powered Umarex Gauntlet that’s quieter and much more powerful.

However, there’s a determined group of enthusiast shooters who like CO2-powered air rifles for their convenience and simplicity. With the 850, they can combine this with high-quality German manufacture and a time-proven design.
