kevG Reg for a Rapid 7 0.22

[ColinH]

Hello KevG,
I have a "bog standard" 0.22 Rapid 7 with 15 3/4" 40mm barrel that I bought from new in Feb 1998 Serial No 006586 that I believe is deemed a MK1 and hence does not have a reg fitted.

I have hardly used the gun but it does shoot well with no apparent problems, and would like some further information on your regulator please and in particular:

1. Pros & cons?
2. Cost and timescales?
3. Can the reg be posted and be simply fitted by me with basic tools and no additional special set ups?

Many thanks in advance, C/
