I have a lovely Sako Quad Synthetic for sale. This comes with .17HMR and Mach2 barrels.
This rifle has the black synthetic stock and the Sako key for changing barrels and currently sits with the Mach2 barrel fitted.
It comes with a 5rnd Mach2 magazine and both 5 and 9rnd mags for the HMR.
The barrels are threaded ½UNF and colour coded to the cartridge size and magazines.
You can also find .22LR and .22WMR barrels will fit as well and the magazines are compatible (17HMR/22WMR and 17Mach2/22LR).
You can have the rifle with either .17 barrel for £300 and if you want the other barrel as well its an extra £100. Barrel on it's own is £150 but I'd like to sell the rifle first to give any potential buyer the most options.
I also have ammo for both size barrels available separately if you want it.
