I was quite late to join the Rapid revolution, always resisted the urge to buy one, but since taking a Tyrolean stocked Mk1 as a part ex against a HW100 I've gotten the bug.
My latest purchase is a Mk2 in the .20 cal, which joins my Mk2 FAC along with the Mk1 .22 Tyrolean stock.
This .20 is really impressing, good groups with JSB and super consistency. The rifle came with a period simmons 6-18x40 pro air which i think were a Theoben recommended scope at the time when it was made - 2002.
Is it ultra quiet? - no, does the bolt clank? - yes, is it bit of a lump - yes, but you know what, they are great.
Many of you fellas use them as your main hunting choice?
