Air Rifle FAC conversion.

How to tune a spring air rifle the cheap way !

Strip the gun down and do a de grease then polish the inside piston chamber with wet and dry wrapped round a wooden dowl in the electric drill you need a mirror finnish
Next replace the the piston seal head and the barrel seal then buy an ox mainspring re oil the piston head and put back together depending on the spring you then need to add metal washers inside the piston in front of the spring adding weight to the piston head end and tightening the spring so when compressed it still engages the trigger !

This will bring your air rifle into a whole new league

I put a gas strutt in my air rifle,nicer to shoot,more consistent and accurate and doesnt loose power anywhere as quickly as a spring

Don't do it! HW35 in .177 would be the last springer you would want to uprate to FAC. HW80 is the best and best in .22 or .25. I have a .177 FAC Daystate, it is lethal but is like putting needles through the quarry.

Also if you do get it uprated to FAC you can never have it delisted, even if it is sub 12ftlb.

There is a very limited market for FAC air rifles so the S/H prices are depressed.

It is dead easy to tune your HW35, I have done lots in the past. Tony at Sandwell Field Sports is the man to talk too if you want a super job done on it.

The HW 35 runs at its best in the 10-11 ft lb region, just a matter of making it a bit more smooth.

Also might be a bit pellet fussy.

If you want to go FAC then PCP and the associated hassle.

Yes you can, it`s just not easy. But I do agree with everything else you`ve said above regards FAC

once went lamping in an open back landy, 1 lamping, 2 shooting..me with my 12ft lb air arms pro-sport and the other guy with a .22 rim ... after the first field it was 12 rabbits to the air rifle and 2 to the rimmy......enough said, you don't need a FAC rated air rifle, i was taking rabbits out to 50 yards through the head every shot and the .22 rim guy was saying you can see the pellet in the lamp, my response was 'yes you can see the pellet in the lamp hitting home everytime, with no richo's' for me 12ft lbs is plenty for an air rifle. just my thoughts Lee

To be fair I suspect the count had more to do with the shooter than comparing .22lr to 12ftlb air.

but back on topic.
I shot springers of dubious quality since I was a kid, first one was bought out of the back pages of the Shooting times mail order for £50 I think!
accounted for numerous magpies, pigeons, crows and mice (yes mice!)
I splashed out a couple of years ago on a PCP (177 Falcon FN12 full kit with pump for £300).
wouldnt go back now. Zero recoil, light, as close to silent as you can get, more accurate than I am and will happily knock magpies out of trees at 50+ yds.
due to the nature of the engineering it is very easy to upgrade this to FAC level if required. Personally I cant see the benefit. I wouldnt contemplate doing it to a springer/GasRam. I have shot a Gas Ram Theoben at FAC level and it has more kick than my 243!
if you need to hit harder get a .22lr
If you need more range get an HMR/M2
