I want to thank all the responders to this inquiry for their recommendations.
Since the two V-Block bolts thread into the aluminum receiver body, on
.22LR models anyway, too much "turn it till it won't turn no more" will probably get you a need to buy a new gun to get a new receiver due to
the serial number placement so I hope to avoid that calamity for fear
that the build i have in mind won't cost a couple of hundred more dollars,
what I have in mind will be pricey enough as it is!!
