Brent,
When Armalite first made the AR_7,it was fairly good but did have the jamming problem. In ;74 Charter Arms took over the manufacturing rights and managed to have the same problem.
When Henry Rifle took over the rights,they made several significant improvements.
Mine is super reliable with high speed solids. Also it now can hold three magazines. Has better sights. They also offer a good carry case for it and a survival kit which is quite comprehensive
If I don't want to use the HS ammo and want silent plinking,I can use CB Longs and being they will not operate the semi auto action,can manually load and fire.
