Hi Mick, i do like your design for the spring guide, you have made for your Hw77k, how much would you be wanting, if i asked you to make me one up of the same design ? also, have you taken delivery of the 10x40 Bushnell ? Whats your thoughts on this type of mag scope ? and what sort of ranges are you shooting to with it. ATB John. P.S i still cant move that end block off the Hw35, but then ive not got access to some desent tools or workshop.
