The very nice man at Merseyside Firearms Licensing gave me the nod on my 17 Fireball project today. I have bought a CZ527 donor in 222, going to mate that with an Archer barrel of about 20mm at the sharp end, threaded M18, then it will be lovingly bedded into a CZ America HS Composite stock and finished off with a Badger Ordnance bolt knob extension . . always wanted a knob extension !!
Will post pics when its born
