A SECRET WEAPON FOR 300-BLACKOUT-AMMO

If I am going 300BO, will probably be build for a can and doubtless ten or twelve inch pistol. Is not going to buy just one if the law won't alter or will get a single down the road when money are offered. My quick barreled 308 features a war comp on it just looking ahead to the legislation to alter.Would you say its as very for a 22Lr sub rather?
