I have an excellent condition Winny M70 SA push feed action with .223 boltface. Comes with trigger, bottom metal, mag box with block and follower/spring. Also included is a B-Square allen head action screw set, never fitted.
This action is from my parted out .300/.221 rifle so it really hasn't seen any 'normal' pressure rounds.
I must have a signed in ink FFL from your dealer.
