sorry guy im out on the road.
cva changed their bolster design no for pellets but becouse of other issues. throughthe yearsthey used 4 diffrent bolsters. 3 if you leave out the snail breachfoun on short production run of kentucks.
with the drum bolster the used 3 diffrent leangh necks.all of wich go into the breech plug. which by the way is of animpoved design.
this design then makes the flash channel on all 3 go strait forwards into the center of the power charge.
what you have to find out, is wich of the 3 bolsters you have, long neck as gorden discribes.
medium nech as lance found on his. or the short neck found on most custom application today.
knowing whzt you have will then tell you how to proceed.
the short anb medium are the simplest to convert. the long neck
can be alittle fun,unless you use the neck of the bolster asa sleve, to put the new liner in.
but to answer yourquestion. yep you can convert it. but i would advise, if your serious,put an RPL lock on it. dont use one of the cva locks. in the long run you will be much happier with the preformance
