Steady grip stock for M2 12 gauge?

[Chesterfield]

I'd like to add a steady grip stock and Burris speed bead to my Benelli M2 12 gauge.  Is this something I can expect to be able to do myself or should I seek the services of a gunsmith?  Thanks for any advice.

Very easy to do yourself.

Thank you for the responses.  I've read that on occasion the fit of the speed bead is not perfect and some customization is required.  I hope that this isn't the case.  I ordered the parts and will give it a try.  Thanks again for the info.
