considering a suppressor
i have a couple builds planned for the future, i plan on suppressing both of the two new guns im building. I am going for a suppressed SBR (not sure if i am going for standard AR look, ACR, or SCAR) and a ruger 10/22 that i can suppress for varmint near the house (i dont wanna waste .223 or 5.56 ammo on a squirrel when a .22lr will do). my question is, if i were to buy a suppressor (say the gemtech halo), would i be able to swap it back and forth between my 10/22 and my AR? would i need to pay a certain tax for it to go on the 10/22 and a separate one for the AR?
i figure there wouldnt be much caliber issue because the two rounds are so similar in diameter or pressure because the halo is designed for 5.56 so i dont see why it shouldnt be able to work effectively with a .22lr.
basically, once i buy a suppressor (and of course the standard $200 BATF tax stamp) can i put it on whatever gun i own that i care to put it on or do i have to buy a halo and an outback IID?
