difference between sub 12ftlbs and FAC

[the Verminator 0]

hi all, thinking of uprating my s410 to fac, i do have a slot on my certifcate for one. do any of the seals or anything need to be changed if it goes up to about 30ftlbs? or is it just a case of upping the power and thats all?

[Guest Scuba1]

Up it and sorted no change of seals needed

easy job as mike has pointed out

 

i think you can get an uprated reg........gives you more consistent power from 1st to last shot....but not silly money.

 

cheers

It needs to be done by a RFD and then registered on your firearms cert and with the local plod. I know someone who could do the work at a reasonable cost. If you pm me i'll give you his number

It depends on the type of S410,,,if it a carbine then there will be VERY few shots at,say,25ft/lbs. The Classic gives a few more but still not enough to warrant upping the power. Also,,the cocking effort goes through the roof,,and the trigger feels awfull compared with the standard S410. Even the S410E,,the FAC level rifle from Air Arms is not very well received. Far better to sell the S410 at 12ft/lbs and buy a Rapid7 allready converted to FAC. The comparative prices won't be too far apart.

youll need to change the exhaust valve,pot,mainspring,probually a bigger tranfer port and hammer

and a different spring guide,easiest thing to do is download internal diagrams of both 12ftlbs and fac and compare the differences between two

And you will still end up with a pigs ear of a rifle. Do the job properly from the start and use a gun that was designed for FAC power from the outset,,ie,,a Rapid.

cheers all, was wondering if it was worth it or not, sounds like not, might get a rapid 7 or something if the price is right? or are there any better rapids?

rapid 7

 

rapid s type

 

or the bsa super ten ( as long as it is blue printed)

 

all worth looking at

 

cheers

Its worth a look on here,,http://www.rapid7ownersclub.com for some good advice on what configuration to go for. A chap called Fluffybuck has some first class data on power levels/barrel length etc. It boils down to sticking between 25 and 30ft/lbs to get the best shot count and not waste air,,with either a 16" or 19" barrel. That way,,you get a reasonable range of pellet sizes/weight that your barrel may like and will stay stable in flight. Higher power FAC air tends to be stuck with Bis Mags which may not suit your purposes. Have a play with ChairGun and see how little trajectory changes once you are running at 26ft/lbs compared with higher outputs. Whichever you choose,,its far cheaper to get a SH air bottle for your rifle,,,to increase shot numbers,,rather than buying a long barrel to do exactly the same.
