ADL to BDL questions

Im putting my ADL style SPS Varmint into a BDL style stock. Im researching all that is needed and some people say you only need the bottom metal and some people say you need the whole conversion kit with the new magazine and spring/follower assembly.

Will my current spring/follower and magazine work in a BDL stock?

Well I found some bottom metal with the mag and spring locally so this question doesn’t concern me anymore. However if someone knows the answer it would be helpful for anyone else searching as I haven’t been able to find anything online.

Call the Wildman. He’ll get you rollin.

I think the mags may be different, depending on the generation of rifle.
