Hello again, this is a review i did for Guerrilla as the first person to buy the 850 from them. (sadly Guerrilla website now vanished!)

All above shot well but only the Air Arms Diablo Hunter Fitted the 8 shot magazine perfectly. All others caused jamming problems on quick re-load. So for the remainder of the test I will be using the Diablo Hunter.
Background information.
This is my first C02 riffle, my preference being good quality spring break barrel or a top of the range Pre-charged rifle. With this in mind I was a little apprehensive testing this rifle, but as the vermin & pest control officer for our local golf club I was asked to find a cheaper yet proficient alternative to the more expensive rifles on the market.
First impressions
I received the rifle less than 24 hours after ordering from Guerrilla.
On opening the box I was impressed at how modern and aesthetically pleasing it was too look at. As this was my first “Plastic” rifle I expected it to feel cheap and light. How wrong I was, it felt solid, well constructed, and expensive far beyond it’s sale value. It was heavy but well balanced.
The 8 shot mag and re-load is smooth and fast. (certain makes of pellets may jam and cause probs)
PS I lost a 8 load mag after 3 days a new 1 will cost you £15 so be careful.
Testing
The setting for this was a small wood at Staden Grange farm 2.5 miles outside Buxton In Derbyshire, a still day at 22.C
I set standard Bisly targets at 30 meters (approx 32 yards)
From the box it took less than 10 minuets to zero the scope (see target on pic) I fired 8 shots in total 4 test then 4 into the blue, over 32 pellets I achieved an average grouping of 1.56 inches (39 mm).
During my research of this rifle I read you can get 400 shots from 1 C02, I thought this was a little ambitious, I achieved 300 at full power and a further 50 at 10 meters less range. The accuracy of this rifle diminished over 35 to 40 meters the question is “ok it hits targets is it a hunter” well see pic, this puppy hit a large buck at 29 meters stone dead, I have now fired over 3000 pellets through this rifle & so far so good.
Tips.
Grease bolt and firing pin regularly to prevent future wear
Rating
Looks and feel 9/10
Performance 8/10 needs cheaper air source and increased range
Total performance and price 9.5/10 (I Love it.)
This is now in service as the preferred vermin & pest control rifle for the Cavendish Golf Club Buxton Derbyshire.
please feel free to comment or ask further questions.!
