Does any here know if the tac a1 and CTR actions are interchangeable? I have a 16" tac a1 in 308. I am mulling over the idea of buying a 20" stainless CTR with the intention of putting it in the tac a1 chassis and putting the 16" in the CTR stock. I will be suppressing both, so I think the 16" will be handy in the standard stock in the woods and just use the 20" tac a1 on the bench. Thank you in advance for the help.
