I have two take down .22lrs... a Browning autoloader and a 10/22 Charger in a PMACA chassis that also has a 16" barrel....the Browning is a Grail Gun from my youth... the 10/22 was a proof of concept design for a light, compact, accurate, high volume of fire, that would not deafen or disorient if it had to be fired inside and auto.... the 16" barrel is used as a backup for my Steel Challenge BRN22 in a PMACA chassis... I don't readily change the barrel just to transport
