Let’s Upgrade The Umarex Fusion 2 Air Rifle

HAM readers gained exclusive first news about the Umarex Fusion 2 air rifle a couple of weeks ago. Now let’s take a look at some ways that we can upgrade this interesting new air rifle.

The first and biggest improvement you can make is to replace the bundled 4×32 scope with a better optic. Yes, it can cost you a very large fraction of the original price of the Fusion 2 air rifle, but it’s well worth the cost!

Better optical performance will make you more accurate. We were looking for a sharper image, Adjustable Objective (AO) parallax correction, higher magnification and mil dot reticle. And we wanted to combine that with a compact size and Picatinny rings.

The answer was a Leapers UTG 3-9 x 32 Bugbuster scope. It mounted onto the Fusion perfectly and was just the right size. Perfect!

This Bugbuster scope fitted tightly onto the Fusion 2’s Picatinny rails, with a few thousandths of space clearance for the magazine! It also provided a nice low eyeline, as you can see in the photographs.

Then we decided to make use of the M-Lok slots in the forend of the stock. It looks as if the slots in the sides of the stock could be used, but there’s not room to do so with the 88 Gram CO2 cartridge in place. That ruled-out the side-mounted UTG M-Lok bipod as we fitted to the SIG Air Virtus recently.

However, the M-Lok slots in the underside of the stock DO work. So we installed an 8-slot UTG M-Lok/Picatinny mount adapter, then mounted a UTG Picatinny-mount bipod to that.

The “tactical” bolt handle of the Umarex Fusion 2 is well-shaped and a good size. It’s also well-knurled for grip. It’s even made of steel! All these are good things, but the result was a little rough for our (too delicate?) fingers…

So, we added three rubber O rings into the slots machined in the bolt handle. Now we had a very comfortable, non-slip grip added to our gun with no dismantling required. The O rings simply rolled right over the end of the bolt handle.

So now we have given our Umarex Fusion 2 air rifle a pleasant upgrade that makes it look, shoot and handle better. And nothing we did voids the warranty or is non-reversible. We like it 🙂
