I’ve just acquired a shorter barrel for my original finnfire P94s varmint. Does anyone know a reasonably simple and accurate method of changing the barrel.
Thanks

I trust you have the headspace gauges for the correct fitment of the new barrel?
I hope the spare barrel is on your FAC!

I was rather hoping someone may just answer the original post

Easy..... take the action out of the stock, you should find 2 hex screws (5mm I think) clamping the barrel in place. You’ll need a long Allen key to undo those as they’re pretty tight and to give you better control.
Swap the 2 barrels aligning the extractor groove with the bolt. Insert a fired case into the chamber, stick the bolt in and with the assembly vertical and just the weight of your arm on the barrel holding it against the bolt...re-tighten the 2 bolts.
Your arm pressure is enough to headspace it off the rim of the fired case and still give enough feel to the bolt. You ‘might’ have to re-visit if you change ammo manufacturer.
I got a .17mach2 barrel from Richard Pope at Swift Precision but he also does .22’s etc......and I’ve stuck 100’s nay, 1000’s of rounds, through these using this headspace method.
There was a thread years ago where someone had drilled 2 corresponding holes in their stock so they didn’t have to faff about removing the action from the stock.

hi bryn, I have a no go gauge for my finnfire, if you want to borrow it I will send it to you as long as you post it back to me, but changing barrels on a finnfire is a 5 minute job. dave.
Did you get my PM?
Will the standard and varmint barrels fit in the same receiver?
