Have received the rifle. Interesting. It is likely ex police. Has last 4 serial numbers engraved into the bolt in the same style as the ex police Brno's did.
Through a real shitty Tasco 2-8 scope of the same vintage it shot 60 grn Norma loads into less than an inch.
Four .223's now :) so have to work out which one goes to my second batch of grandsons that are getting keen.
