There isn't a good kit, in my opinion.
Devcon 10110 Plastic Steel Putty
Popsicle sticks and/or wooden shishkabob skewers
Entire Box of 50 pairs of Nitrile Gloves
Lots of paper towel and/or little rags
Small bowl of mineral spirits
Bottle of NuFinish Car wax
Entire Box of GOOD Q-tips
One straight razor blade and/or an exacto-knife set
A roll of 1" and a roll of 2-3" Blue 3M painter's tape.
A container of Acetone
Kids Modelling clay
Small table fan to blow the fumes from the chemicals away from you
Timer or watch
Electronic reloading scale that can be tared
Dremel tool with appropriate bits to remove stock area to be bedded
Pillars, if desired
Piloted counter-bore bit or forstner bit, if installing pillars
Small flat-bladed optical screwdrivers can be handy
--Wear old clothes.
--Do not attempt this job on your kitchen counter for the first time.
--Do not be stingy with the gloves.
--Do not be stingy with the wax. Do not rush the wax drying.
--Wax and/or tape EVERYTHING you don't want epoxy on.
--Don't mix the epoxy until you're truly ready to go down to the last detail.
--Other than backing the screws off a 1/4 turn at 4 hours, don't touch the rifle for 24 hours after gluing it. Just don't.
The PREP and CLEANUP for this job take about twice as long as the actual process.
Except for the Devcon and the pillars, most of this list should be available between your home town Walmart and hardware store.
