Couple of months ago I bought a second hand Ruger M77 MKII in 223 from the Skipton Gun Room.
I had a few problems with it, after the gun coming back from the gunsmith (at the shops expense) the problem was still not corrected. Phil (the owner) offered me a full refund or part exchange for any gun in the shop without a seconds thought!
Phil kept the shop open late, so I could drop the gun off after work and on arrival offered me a cuppa. We had a chat and ended up being offered his Remington 700 in 223.
When the variation came back and went to pick up the Remy, he threw in a box of 55gn hornady v-max and again apologised!
Every time I have been to this shop the customer service has been first class and both lads there are true gents, and offer a great service. All the stock is competitively priced and nothing is too much trouble to get ordered in.
I recommend you pay a visit if you are in the area, its hard to find a shop that provides quality customer service these days!
I do not have any affiliation with the shop by the way!!
